Consider the following which can be found in the ambient atmosphere

Consider the following which can be found in the ambient atmosphere:
1. Soot
2. Sulphur hexafluoride
3. Water vapour
Which of the above contribute to the warming up of the atmosphere?

(a)

1 and 2 only

(b)

3 only

(c)

2 and 3 only

(d)

1,2 and 3

Explanation

All three elements mentioned in the question contribute to the warming of the atmosphere and therefore, the correct answer is option 4. 1. Soot: It absorbs sunlight and warms up the atmosphere. Soot particles can also become embedded in snow and ice, reducing their reflectivity and increasing melt rates. 2. Sulphur Hexafluoride: It is an extremely potent greenhouse gas. It is over 23,000 times more warming than carbon dioxide (CO2). Even in small amounts, Sulphur Hexafluoride contributes significantly to global warming. 3. Water vapour: It is the most abundant greenhouse gas in the atmosphere and plays a crucial role in Earth’s climate. It traps heat from the sun and contributes to the warming of the Earth`s surface. Each option only partially acknowledges these contributors, whereas option 4 correctly includes all three.
