उत्तर और व्याख्या · explanation in English
Answer: (b) 1 और 2
The Peninsular Block is an ancient, rigid landmass whose western edge has partly sunk beneath the sea and whose hills are old, worn-down remnants such as the Veliconda and Mahendragiri ranges. Its river valleys are shallow, so deep V-shaped valleys belong instead to the young Himalayan mountains.
- ✓ 1. NCERT describes the Peninsula as a rigid block since the Cambrian, except for part of its western coast that lies submerged beneath the sea, with other parts altered by tectonic activity.
- ✓ 2. The Peninsula mostly consists of relict and residual mountains, and NCERT lists the Veliconda hills and the Mahendragiri hills among them.
- ✗ 3. Peninsular river valleys are shallow with low gradients. Gorges and V-shaped valleys are marks of the young, fast-flowing rivers of the Himalayan mountains.
Remember · Peninsular Block: ancient rigid block, submerged western coast, relict and residual hills (Aravali, Nallamala, Veliconda, Mahendragiri), shallow valleys. V-shaped valleys are Himalayan.
