  • Foreign Policy Watch: India – EU

    Europe as a valuable strategic partner

    op-ed snap | International Relations | Mains Paper 2: Bilateral, Regional and Global Groupings and agreements involving India

    Context

    Last week’s in-person summit in Delhi was with the Danish prime minister, Mette Frederiksen.

    Europe as a valuable partner

    • Few Asian countries view Europe with strategic suspicion. Many in Asia see Europe as a valuable partner.
    • As the deepening confrontation between the US and China begins to squeeze South East Asia, Europe is widely seen as widening the strategic options for the region.
    • The perspective is similar in Delhi, which now sees Brussels as a critical element in the construction of a multipolar world.
    • Cultivate Europe: As External Affairs Minister Subrahmanyam Jaishankar puts it, India’s strategy is to “engage America, manage China, cultivate Europe, reassure Russia, bring Japan into play”.
    • EU’s Strategy for India: The EU outlined a strategy for India in 2018 to focus on four themes — sustainable economic modernisation, promotion of a rules-based order, foreign policy coordination, and security cooperation.
    • At the summit in Portugal in May this year, the EU and India agreed to resume free trade talks and develop a new connectivity partnership that would widen options for the world beyond the Belt and Road Initiative.
    • Rebalancing the international system: Above all, there is a recognition in both Delhi and Brussels that the India-EU strategic partnership is crucial for the rebalancing of the international system amidst the current global flux.

    Possibilities with smaller European countries

    • Europe looms so large in the Indian diplomatic agenda today and smaller European states draw unprecedented political attention from Delhi.
    • That Denmark, a country of barely six million people, can establish a significant green partnership with India, is a reminder that smaller countries of Europe have much to offer in India’s economic, technological, and social transformation.
    • Luxembourg brings great financial clout, Norway offers impressive maritime technologies, Estonia is a cyber power, Czechia has deep strengths in optoelectronics, Portugal is a window to the Lusophone world, and Slovenia offers commercial access to the heart of Europe through its Adriatic sea port at Koper.
    • As India begins to realise this untapped potential, there are new openings with the 27-nation EU headquartered in Brussels.

    EU’s important role in Indo-Pacific

    • The EU’s Indo-Pacific strategy is likely to have a much greater impact on the region more immediately and on a wider range of areas than military security.
    • Area’s of impact range from trade and investment to green partnerships, the construction of quality infrastructure to digital partnerships, and from strengthening ocean governance to promoting research and innovation.
    • Defence and security are important elements of the EU’s Indo-Pacific strategy that “seeks to promote an open and rules-based regional security architecture, including secure sea lines of communication, capacity-building and enhanced naval presence in the Indo-Pacific.
    • Whatever the specific circumstances of the AUKUS deal and its impact on France, the US wants all its partners, especially Europe, to contribute actively to the reconstitution of the Asian balance of power.
    • Working with Quad: The EU strategy, in turn, sees room for working with the Quad in the Indo-Pacific, while stepping up security cooperation with a number of Asian partners, including India, Indonesia, Japan, the Republic of Korea, Singapore and Vietnam.
    • India is conscious that Europe can’t match America’s military heft in the Indo-Pacific.
    • But it could help strengthen the military balance and contribute to regional security in multiple other ways.

    Consider the question “Delhi knows that Europe could significantly boost India’s capacity to influence future outcomes in the Indo-Pacific. It would also be a valuable complement to India’s Quad coalition”. Comment.

    Conclusion

    It was Russia that defined India’s discourse on the multipolar world after the Cold War. Today, it is Europe — with its much greater economic weight, technological strength, and normative power — that promises to boost India’s own quest for a multipolar world and a rebalanced Indo-Pacific.

  • Foreign Policy Watch: India-China

    Explained: Patrolling Points along LAC

    | International Relations | Mains Paper 2: Bilateral, Regional and Global Groupings and agreements involving India

    The standoffs between Indian and Chinese troops in Ladakh on the Line of Actual Control (LAC), where initial steps towards disengagement have taken place, are around a number of patrolling points or PPs in Galwan, Hot Springs and Gogra areas.

    What exactly are Patrolling Points?

    • PPs are patrolling points identified and marked on the LAC, which are patrolled with a stipulated frequency by the security forces.
    • They serve as a guide to the location of the LAC for the soldiers, acting as indicators of the extent of ‘actual control’ exercised on the territory by India.
    • By regularly patrolling up to these PPs, the Indian side is able to establish and assert its physical claim about the LAC.

    Are all the Patrolling Points numbered?

    • Some of the PPs are prominent and identifiable geographical features, such as a pass, or a nala junction where no numerals are given.
    • Only those PPs, where there are no prominent features, are numbered as in the case of PP14 in Galwan Valley.

    Are all on the Patrolling Points bang on the LAC?

    • Mostly, yes. Except for the Depsang plains in northern Ladakh, where PP10, PP11, PP11A, PP12 and PP13 – from Raki Nala to Jivan Nala – do not fall on the LAC.
    • These are short of the LAC, on the Indian side.

    Are these Patrolling Points not manned?

    • The PPs are not posts and thus not manned.
    • Unlike on the Line of Control (LoC) with Pakistan, the border with China is not physically held by the Army all along.
    • They are just physical markers on the ground, chosen for their location and have no defensive potential or tactical importance for the Army.

    If the Patrolling Points are not manned, how is the claim actually asserted?

    • The claim is asserted by the Army or joint Army-ITBP patrols as they show more visible presence in these areas.
    • This is done by physically visiting PPs with a higher frequency, as the deployment has moved closer to the LAC and due to improved infrastructure.
    • As the Chinese may not see when the Indian patrols visit these PPs, they will leave come cigarette packets or food tins with Indian markings behind.
    • That lets the Chinese know that Indian soldiers had visited the place, which indicates that India was in control of these areas.

    Who has given these Patrolling Points?

    • These PPs have been identified by the high-powered China Study Group, starting from 1975 when patrolling limits for Indian forces were specified.
    • It is based on the LAC, after the government accepted the concept in 1993, which is also marked on the maps with the Army in the border areas.
    • But the frequency of patrolling to PPs is not specified by the CSG – it is finalised by the Army Headquarters in New Delhi, based on the recommendations made by the Army and ITBP.

    What is this frequency?

    • The frequency of reaching various PPs are given in the annual patrolling programme.
    • Based on the terrain, the ground situation and the location of the LAC, the duration for visiting each PP is specified – it can vary from once a month to twice a year.

    Major friction area: Hot Springs

    • Hot Springs lies in the Chang Chenmo River valley, close to Kongka La, a pass that marks the Line of Actual Control.
    • India’s Patrolling Point 15, it is not a launchpad for any offensive action though the area did see action before and during the 1962 war.
    • China’s unwillingness to pull back its platoon-sized unit from Hot Springs is a sign of the difficulties that lie in normalising the situation.
    • The PLA has traditionally had a major base east of Kongka La.
    • The pass also marks the border between two of China’s most sensitive provinces — Xinjiang to the north and Tibet to the south.

  • Nobel and other Prizes

    Economics Nobel for Natural Experiments

    Prelims Only | Trivia | Mains Paper 3: Inclusive Growth & Issues

    The 2021 Nobel Prize in Economic Sciences was awarded to three US-based economists.

    Do you know?

    The Nobel Prize is officially called as Sveriges Riksbank Prize!

    Who are the awardees?

    • Nobel Committee awarded half the Prize to David Card for his “empirical contributions to labour economics”
    • Other half to Guido Imbens and Joshua Angrist “for their methodological contributions to the analysis of causal relationships”

    What makes this year’s award special?

    • This is the first time the economic prize has been divided in this fashion with one half going to one awardee and other half divided across two awardees.
    • In the past, prize money was divided equally between the awardees even if the prize was for different topics as is the case this time around.
    • It may appear that the Nobel Prize has been given for two different contributions, but there is a common theme: “natural experiments.”

    What are Natural Experiments?

    • Economists are often interested in causal questions such as the impact of education on incomes, impact of COVID-19 on poverty and so on.
    • They are also interested is understanding the direction of causality.
    • Economists have used two kinds of experiments to study these causality and direction of causality questions: random experiments and natural experiments.

    (I) Random experiments

    • Under randomized experiments, the researchers allocate say medicines to a treatment group and compare the effect of the medicine with the control group which is not given the medicine.
    • In 2019, the Nobel Committee gave awards to three scholars for their contribution to the field of randomized experiments.
    • However, one cannot randomize experiments to study issues such as why certain people and regions are more unequal or have fewer educational opportunities and so on.

    (II) Natural experiments

    • In natural experiments, economists study a policy change or a historical event and try to determine the cause and effect relationship to explain these developments.
    • The trio used such natural experiments to make some landmark contributions to economic development.
    • Natural experiments are more difficult for two reasons. The first is to identify what will serve as a natural experiment.
    • Second, in a random experiment, the researcher knows and controls the treatment and control groups which allows them to study the cause and effect of medicine.
    • But in natural experiments, such clear differentiation is not possible because people choose their groups on their own and even move between the two groups.
    • Despite the limitations, the researchers could use the natural setting to answer some big policy questions.

    Natural experiments conducted by David Card

    • One question of interest for policymakers is to understand the impact of higher minimum wages on employment.
    • Earlier studies showed that increasing minimum wages leads to lower unemployment.
    • Economists were also not sure of the direction of causation between minimum wages and employment.
    • Say a slowdown in the economy leads to higher unemployment amid lower income groups.
    • This could lead to lower income groups demanding higher minimum wages. In such a case, it is higher unemployment which leads higher minimum wages.

    Contribution of Angrist and Imbens

    • Angrist and Imbens showed how natural experiments can be used to identify cause and effect precisely.
    • We have discussed above how natural experiments make it difficult to separate control and treatment groups. This makes it difficult to establish causal relations.
    • In the 1990s, the duo developed a methodology – Local Average Treatment Effect (or LATE) – which uses a two-step process to help grapple with these problems of natural experiments.
    • Say, one is interested in finding the impact of an additional year of schooling on the incomes of people.
    • By using the LATE approach, they showed that effect on income of an additional year of education is around 9%.
    • While it may not be possible to determine individuals in the group, one can estimate the size of the impact.

    What is the importance of the award today?

    • Earlier it was difficult to identify natural experiments and even if one identified them, it was difficult to generate data from these experiments.
    • With increased digitalization and dissemination of archival records, it has not just become easier to identify natural experiments but also get data.
    • Economists have been using natural experiments to help us understand the impact of past policies.
    • As the 2020 pandemic struck, economists used the natural experiments approach extensively to analyse how previous pandemics impacted different regions and tried to draw policy lessons.

    India context

    • The methodology date back to the early and mid-90s and they have already had a tremendous influence on the research undertaken in several developing countries such as India.
    • For instance, in India, too, it is commonly held that higher minimum wages will be counterproductive for workers.
    • It is noteworthy that last year, in the wake of the Covid-induced lockdowns, several states, including UP, had summarily suspended several labour laws.
    • This included the ones regulating minimum wages, arguing that such a move will boost employment.
    • The main learning is that minimum wages can be increased in India without worrying about reducing employment.

  • ISRO Missions and Discoveries

    [pib] Indian Space Association

    PIB | Science Tech | Mains Paper 3: Effects Of Liberalization On The Economy, Changes In Industrial Policy and their effects on Industrial Growth

    The PM has launched the Indian Space Association (ISpA), an industry body consisting of various stakeholders of the Indian space domain.

    Indian Space Association (ISpA)

    • The ISpA is a premier industry association of space and satellite companies, which aspires to be the collective voice of the Indian space industry.
    • It will be headed by retired Lieutenant General AK Bhatt, who will be its Director General.
    • It will target to undertake policy advocacy and engage with all stakeholders in the Indian space domain. It will engage with the government and all its agencies.

    Why is the formation of ISpA significant?

    • Million-dollar industry: Governments across the world have poured millions of dollars to push the envelope in term of exploring the edges of the space.
    • Collaborated research: With time, governments and government agencies collaborated to explore newer planets and galaxies in search of life forms that exist outside Earth.
    • Private players involvement: In the recent past, private sector companies such as Elon Musk’s SpaceX, Richard Branson’s Virgin Galactic, and Jeff Bezos’ Blue Origin have taken the lead in spaceflight.
    • Easing workload on ISRO: Though India too has made significant strides in space exploration over time, state-run ISRO has been at the centre and front of this progress.

    What does ISpA aim to achieve?

    • Supplementing space research: One of the main goals of the organisation is to supplement the government’s efforts towards making India a global leader in commercial space-based excursions.
    • Commercial space exploration: ISpA said it would engage with stakeholders across the ecosystem for the formulation of an enabling policy framework which fulfills the government vision of leading commercial space exploration.
    • Establishing global linkages: ISpA will also work towards building global linkages for the Indian space industry to bring in critical technology and investments into the country to create more high skill jobs.

    Who are the stakeholders in this organisation? How will they contribute?

    • ISpA will be represented by leading domestic and global corporations that have advanced capabilities in space and satellite technologies.
    • It has taken off with several Indian and international companies betting on it as the next frontier to provide high-speed and affordable Internet connectivity to inaccessible areas as well.
    • This includes SpaceX’s StarLink, Sunil Bharti Mittal’s OneWeb, Amazon’s Project Kuiper, US satellite maker Hughes Communications, etc.
    • OneWeb, for example, is building its initial constellation of 648 low-earth orbit satellites and has already put 322 satellites into orbit.

    Why is satellite-based Internet important in India?

    • The expansion of the Internet in India is crucial to the Modi government’s dream of a digital India where a majority of government services are delivered directly to the customer.
    • The government aims to connect all villages and gram panchayats with high-speed Internet over the next 1000 days through BharatNet.
    • However, internet connectivity in hilly areas and far-flung places of Northeast India are still a challenge.
    • To overcome this, industry experts suggest that satellite Internet will be essential for broadband inclusion in remote areas and sparsely populated locations where terrestrial networks have not reached.
    • Satellite communications remain limited to use by corporates and institutions that use it for emergency use, critical trans-continental communications and for connecting to remote areas with no connectivity.

    WTO raises 2021 goods trade outlook

    IOCR | Economics | Mains Paper 3: Indian Economy

    The World Trade Organization (WTO) has upgraded its world merchandise trade growth outlook to nearly 11 percent for this year, higher than 8% estimated in March.

    About WTO

    • The World Trade Organization (WTO) is an intergovernmental organization that regulates and facilitates international trade between nations.
    • Governments use the organization to establish, revise, and enforce the rules that govern international trade.
    • It officially commenced operations on 1 January 1995, pursuant to the 1994 Marrakesh Agreement, thus replacing the General Agreement on Tariffs and Trade (GATT) that had been established in 1948.
    • The WTO is the world’s largest international economic organization, with 164 member states representing over 96% of global trade and global GDP.
    • The WTO facilitates trade in goods, services and intellectual property among participating countries.
    • It prohibits discrimination between trading partners, but provides exceptions for environmental protection, national security, and other important goals.

    Report on Global trade

    • According to a WTO, global goods trade is expected to grow by 10.8 per cent compared to the forecast of 8 per cent in March, but with varied recovery, depending on the region.
    • The report said export volume growth in 2021 will be 8.7 per cent in North America, 7.2 per cent in South America, 9.7 per cent in Europe, 7 per cent in Africa, 5 per cent in West Asia and the highest for Asia at 14.4 per cent.
    • On the other hand, imports are expected to grow at a faster pace as compared to exports. Inbound shipments into North America are set to grow by 12.6 per cent.
    • It will be 19.9 per cent in South America, 9.1 per cent in Europe, 13.1 per cent in CIS, 11.3 per cent in Africa, 9.3 per cent in West Asia and 10.7 per cent in Asia.

    Key highlights for India

    • Exports from India have been rising consistently over the last few quarters, after plummeting for a few months as the outbreak of Covid-19 disrupted global trade.
    • India’s exports to its top trading partners such as the US, European Union, nations in West Asia, among others, are expected to rise.
    • Exports data during the first six months of the current fiscal year is emblematic of the fact that external demand has been robust.
    • Besides, supply-side disruptions can also be exacerbated by the rapid and unexpectedly strong recovery of demand in advanced and many emerging economies.

    Competing with China

    • Experts said with rising global demand, India should be able to compete in various segments vis-a-vis China.
    • Currently, China is facing supply-side as well as demand-side issues owing to several internal challenges (energy, debt crisis).
    • Therefore, India is in a good position to increase its exports, and can become a substitute for China across various product categories or sectors.
    • India can take advantage of the increasing global demand, which can ultimately translate into demand for Indian exports.

  • Tax Reforms

    Explained: Global Minimum Tax Deal

    IOCR | International Relations | Mains Paper 2: Bilateral, Regional and Global Groupings and agreements involving India

    A global deal to ensure big companies pay a minimum tax rate of 15% and make it harder for them to avoid taxation has been agreed by 136 countries.

    What is the news?

    • The OECD said four countries – Kenya, Nigeria, Pakistan and Sri Lanka – had not yet joined the agreement.
    • However, the countries behind the accord together accounted for over 90% of the global economy.

    Why a global minimum tax?

    • With budgets strained after the COVID-19 crisis, many governments want more than ever to discourage multinationals from shifting profits – and tax revenues – to low-tax countries.
    • Increasingly, income from intangible sources such as drug patents, software and royalties on intellectual property has migrated to these jurisdictions.
    • This has allowed companies to avoid paying higher taxes in their traditional home countries.
    • The minimum tax and other provisions aim to put an end to decades of tax competition between governments to attract foreign investment.

    How would a deal work?

    • The global minimum tax rate would apply to overseas profits of multinational firms with 750 million euros ($868 million) in sales globally.
    • Govts could still set whatever local corporate tax rate they want.
    • However, buif companies pay lower rates in a particular country, their home governments could “top up” their taxes to the 15% minimum, eliminating the advantage of shifting profits.
    • A second track of the overhaul would allow countries where revenues are earned to tax 25% of the largest multinationals’ so-called excess profit – defined as profit in excess of 10% of revenue.

    What happens next?

    • The next step is for finance ministers from the Group of 20 economic powers to formally endorse the deal, paving the way for adoption by G20 leaders at an end October summit.
    • Nonetheless, questions remain about the US position which hangs in part on a domestic tax reform the Biden administration wants to push through the US Congress.
    • The agreement calls for countries to bring it into law in 2022 so that it can take effect by 2023, an extremely tight timeframe given that previous international tax deals took years to implement.
    • Countries that have in recent years created national digital services taxes will have to repeal them.

    What will be the economic impact?

    • The OECD, which has steered the negotiations, estimates the minimum tax will generate $150 billion in additional global tax revenues annually.
    • Taxing rights on more than $125 billion of profit will be additionally shifted to the countries were they are earned from the low tax countries where they are currently booked.
    • Economists expect that the deal will encourage multinationals to repatriate capital to their country of headquarters, giving a boost to those economies.
    • However, various deductions and exceptions baked into the deal are at the same time designed to limit the impact on low tax countries like Ireland, where many US groups base their European operations.

    Back2Basics: Base Erosion and Profit Shifting (BEPS)

    • BEPS refers to corporate tax planning strategies used by multinationals to “shift” profits from higher-tax jurisdictions to lower-tax jurisdictions.
    • It thus “erodes” the “tax base” of the higher-tax jurisdictions.
    • Corporate tax havens offer BEPS tools to “shift” profits to the haven, and additional BEPS tools to avoid paying taxes within the haven.
    • It is alleged that BEPS is associated mostly with American technology and life science multinationals.

  • Animal Husbandry, Dairy & Fisheries Sector – Pashudhan Sanjivani, E- Pashudhan Haat, etc

    Using Paddy Straw as Cattle Feed

    | Enviro & Biodiversity | Mains Paper 3:

    Punjab has now proposed to use the paddy crop residue as fodder for animals, especially cattle.

    Why such a move?

    • In Punjab, the total availability of paddy straw is about 20 million tones per annum.
    • The total value of this straw is Rs 400 crore approx., calculated on an average rate of Rs 200/quintal. Almost all of it is burnt in fields.
    • This accounts for economic loss apart from the loss of 77,000 tonnes of nitrogen and 5.6 million tonnes of Total Digestible Nutrients (TDN) which could be used for ruminant production.
    • Also nearly 30.4 per cent of rice straw is used for animal feed in Southeast Asia, Mongolia and China.

    Economics behind paddy straw

    • High silica and lignin content reduces its digestive properties.
    • Higher selenium content in paddy straw also limits its use as fodder in animals as compared to wheat straw.
    • However, if given in moderate quantities (up to 5 kg per animal per day), selenium poses no health hazard to the animal.
    • Paddy straw also contains oxalates (2-2.5%) which leads to calcium deficiency so mineral mixture should always be fed along with the straw.

    Treatments for feeding paddy straw to animals

    • Paddy Straw cannot be directly fed to animals. It has to undergo some treatments.
    • Two of them are: Urea-only treatment and urea plus molasses treatment.

    [A] Urea treatment of paddy straw

    • 14 kg of urea is dissolved in 200 litres water and spray on chopped paddy straw.
    • The fermented straws have soft texture with 6.0-8.0 per cent crude protein, 3.0-4.0 percent DCP and 55-60 per cent TDN.
    • This involves a combination of physical, chemical and biological treatments.
    • The paddy straw is chaffed and moistened (physical) with urea solution (chemical).
    • The breakdown of urea release ammonia gas, a part of which is utilised by microbes (biological) for their proliferation (enriching the straw with microbial protein).
    • This in turn results in breakage of lingo-cellulosic bonds making cellulose and hemi-cellulose assessable for utilization by microbes in the rumen.
    • The digestibility of cellulose increases from 40-45% in untreated paddy straw to 70-75 per cent in fermented wheat straw.

    [B] Urea plus molasses treatment

    • Also called “Urea-Molasses impregnated straw”, this method involves treating paddy straw with urea and molasses.
    • Urea 1 kg and molasses 3 kg was mixed thoroughly and mixed with water 10 kg. This is mixed with chaffed paddy straw and fed to animals on same day.
    • The experts however clarify that for maintenance of body weight in animals, paddy straw alone is not sufficient.
    • Minerals and green fodder supplementation is required.

    How does the nutritional value of paddy straw increase after urea treatment?

    • The TDN values in urea treated paddy straw increased manifold as compared to untreated straw.
    • Crude protein (CP) increased from 4.5% to 8%, digestible crude protein (DCP) from 1.5% to 4% and total digestible nutrients (TDN) from 40% to 55%.
    • The feeding of urea treated straw (6 kg/day) to lactating buffaloes giving about 10 kg milk/day can result in saving about 60 per cent of oilseed cake in the ration.
    • Feeding of paddy straw should be mixed with berseem, cowpea or Lucerne as it forms a maintenance ration.
    • The straw should be fed with concentrate mixture and additional DCP or limestone should be given to the animals to reduce the effect of oxalates.
    • Oxalates also interfere in carbohydrate metabolism perhaps due to non-availability of calcium as cofactor.

    What are the potentially harmful effects?

    • The intake of siliceous forages has been associated with urinary siliceous calculi in drier regions where water may be limited.
    • There have been no definitive studies in India, but urinary calculi are associated with rice straw consumption.
    • It has high selenium (0.5 to 4.5 % ) content which can cause serious health problems in dairy animals.

    Indian meteorite helps study Earth’s formation

    Prelims Only | Science Tech | Mains Paper 3: Awareness in various sc and tech fields

    The researchers from the Geological Survey of India collected about 30 meteorite fragments with the largest weighing around a kilogram near the town of Katol in Nagpur in 2012.

    Significance of meteor study

    • Now, by studying the composition of these meteorite fragments, researchers have unraveled the composition expected to be present in the Earth’s lower mantle which is at about 660 km deep.
    • Studying the meteorite could also tell us more about how our Earth evolved from being a magma ocean to a rocky planet.

    Key component of the Meteor: Olivine

    • Initial studies revealed that the host rock was mainly composed of olivine, an olive-green mineral.
    • Olivine is the most abundant phase in our Earth’s upper mantle.
    • Our Earth is composed of different layers including the outer crust, followed by the mantle and then the inner core.

    How to study a meteorite?

    • The researchers took a small sample of the meteorite and examined it using special microscopy techniques.
    • The mineralogy was determined using a laser micro-Raman spectrometer.
    • These techniques helped the team identify, characterise the crystal structure of the meteorite and determine its chemical composition and texture.

    What does the new study show?

    • The international team of scientists examined a section of this highly-shocked meteorite. It resembles to the first natural occurrence of a mineral called bridgmanite.
    • The mineral was named in 2014 after Prof. Percy W. Bridgman, recipient of the 1946 Nobel Prize in Physics.
    • Various computational and experimental studies have shown that about 80% of the Earth’s lower mantle is made up of bridgmanite.
    • By studying this meteorite sample, scientists can decode how bridgmanite crystallized during the final stages of our Earth’s formation.

    Bridgmanite: On Earth vs. on Meteorite

    • Katol meteorite is a unique sample and it is a significant discovery.
    • The bridgmanite in the meteorite was found to be formed at pressures of about 23 to 25 gigapascals generated by the shock event.
    • The high temperature and pressure in our Earth’s interior have changed over billions of years causing crystallisation, melting, remelting of the different minerals before they reached their current state.
    • It is important to study these individual minerals to get a thorough idea of how and when the Earth’s layers formed.

    How does it help understand evolution of Earth?

    • The inner planets or terrestrial planets or rocky planets Mercury, Venus, Earth, and Mars are formed by accretion or by rocky pieces coming together.
    • They were formed as a planet by increased pressure and high temperature caused by radioactive elements and gravitational forces.
    • Our Earth was an ocean of magma before the elements crystallised and stabilised and the different layers such as core, mantle were formed.
    • The heavier elements like iron went to the core while the lighter silicates stayed in the mantle.
    • By using the meteorite as an analog for Earth, we can unearth more details about the formation.
