Geologically, which of the following physiographic divisions of India is supposed to be one of the most stable land blocks?
Show answer & explanation
Correct answer: C
Explanation
The correct answer is option 3 i.e. The Peninsular Plateau.
The Peninsular Plateau is considered Earth's most stable land block due to its ancient geological history. Formed primarily from crystalline igneous and metamorphic rocks dating back billions of years (Precambrian era), it's a remnant of the supercontinent Gondwana. Unlike the young, seismically active Himalayas, the Peninsular Plateau has experienced minimal tectonic activity, folding, or faulting in recent geological times. This long period of stability has resulted in a rigid, denuded landscape with rounded hills and shallow valleys, signifying its resilience to significant geological upheavals.
