GEOGRAPHY Chapter 2: Physical Features of India
(1) PHYSICAL FEATURES OF INDIA 02 Physical Features of India We find various types of landform features in India because its geographical extent is very vast. While the eastern part of our country is uneven, rugged, and hilly, the Ganga– Brahmaputra region has vast stretches of plain lands. Formation of the Land Forms • Several factors such as the presence of different types of rocks, geological formations, weathering, erosion and deposition have influenced and affected the land features of India. • Geologists have forwarded various theories regarding the formation of the physical features of the Earth. • One of the most probable theories is the ‘Theory of Plate Tectonics’. This theory postulates that the crust of the Earth has been formed out of seven major and some minor plates. • The movement of the plates beneath the surface of the Earth creates tension, resulting in folding, faulting and volcanic activities. • Plate movements are broadly categorised into three different types. When the plates come towards each other, they form convergent boundaries. When the plates move away from each other, they form divergent boundaries. Transform boundaries are formed when the plates horizontally move past each other. • All these movements of the plates have gradually changed the size and the position of the continents over millions of years.
