Which of the following geographical features or phenomena is/are associated with the Peninsular Block of India ? 1. Submergence of parts of the western coast due to tectonic activity 2. 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 :
A
1 only
B
1 and 2
Correct answer
C
2 and 3
D
3 only
Explanation
The Peninsular Block is a stable shield of ancient rocks. Parts of it subsided along faults, which is why the western coast is described as a submerged coastline, and it carries worn-down residual ranges such as the Aravallis, Nallamala, Veliconda, Palkonda and Mahendragiri hills. Deep V-shaped valleys cut by fast-flowing rivers belong to the young Himalaya. Peninsular rivers flow in broad, shallow, mature valleys, so 3 is wrong.
