Presence of residual mountain ranges such as the Veliconda hills and Mahendragiri hills 3. Deep, V-shaped river valleys formed by fast-flowing rivers Select the answer using the code given below:

  1. 1 only
  2. 1 and 2
  3. 2 and 3
  4. 3 only

Answer

Correct Answer

1 and 2

Explanation

The Peninsular Block is an ancient and relatively stable geological region, but parts of its western coast have experienced submergence associated with tectonic and geological processes. Residual or relict ranges such as the Veliconda Hills and Mahendragiri Hills are also associated with Peninsular India. Deep V-shaped valleys formed by rapidly flowing youthful rivers are more characteristic of the Himalayan region, so statement 3 is incorrect.
