Question

The oldest landmass of India is ……………………
A. The Peninsular Plateau
B. The Himalayan mountains
C. The Coastal Plains
D. The Indian Dessert

Answer 1

Hint: The term landmass can be described as a large area of continental crust. Such masses of land are often surrounded by any water body like the ocean or sea. Examples of landmass include continent, large island, etc.

Complete Answer:
The ancient supercontinent Pangea was divided into two parts, which are known as Gondwanaland and Angara land. The Peninsular plateau of India is located in the south of the Northern Plains and it is bordered by Hill Ranges on all sides.
The part of Gondwanaland further day assembled into many parts and broken down into different parts. Around 180 million years ago, this disassembly occurred. The block of the peninsular plateau is one of the landmasses into which the Gondwanaland has drifted away.
The Collision of the Indian landmass and Eurasia occurred between 40 and 50 million years ago. This has resulted in the formation of the mountain ranges of the present-day Himalayas. So, option B is incorrect. Coastal plains are meant by low lying flat areas observed adjacent to any seacoast. Coastal plains were formed very a few years back. So option C is incorrect.
The Indian desserts which are often known as marusthalis were formed around 70,000 years ago. Hence, this desert is not considered the oldest landmass of India. So option D is incorrect.
We can infer that the oldest landmass of the Indian subcontinent is the peninsular plateau.
So, the correct answer is Option A.

Note: The theory of plate tectonics describes the phenomenon by the virtue of which the various landforms are formed across the different regions of the globe. This branch of Geography is known by the name of Geomorphology.
