On the basis of prominent relief features, the peninsular plateau can be divided into three broad groups:
Let’s take up these divisions one by one:
1. The Central Highlands
2. The Deccan Plateau
3. The Northeastern Plateau:
Most of the hills in the peninsular region are of the relict type (residual hills). They are the remnants of the hills and horsts formed many million years ago (horst: uplifted block; graben: subsided block).
The plateaus of the Peninsular region are separated from one another by these hill ranges and various river valleys.
1. The Aravalli Mountain Range:
2. Vindhyan Ranges:
3. Satpura ranges:
4. Western and Eastern Ghats:
Note: The Western Ghats are continuous and can be crossed through passes only. There are four main passes which have developed in the Western Ghats. These are:
For the geographical location of these passes, see the following map:
Now that we are done with this part, let’s try to attempt some questions from the past UPSC examinations:
