The region is characterised by senile topography.
But The Eastern Ghats stretch from Mahanadi Valley to the Nilgiris in the south. The difference between these two rock types is: basalt rock forms on eruption of lava, that is, on the surface either out of a volcano, or through massive fissures—as in the Deccan basalts—in the ground , while granite forms deep within the Earth. Only Sutlej, another trans-Himalayan river and a tributary of Indus flows for its major cause through India, while Beas, a tributary of Sutlej, remains in India throughout its journey in the plains.

The Deccan Plateau, which is roughly of a triangular shape, extends from the Satpura hills in the north to Kanyakumari, the southernmost tip of India ending in the Indian Ocean. It is considerably broad in the west and becomes narrowed to the east. The Deccan Trap is of volcanic origin.
The Vindhyas and its eastern stretches enclose the one situated to the north on one region. Rakaposhi steepest peak in the world. The Deccan plateau is part of the Peninsular Plateau.

The Chhota Nagpur Plateau is the eastern extension of the Central Highlands. The plateau's forests are moist deciduous, dry deciduous, and tropical thorn. The area has been carved into a rolling plain by the erosional work of the Banas river and its tributaries. The administrative headquarters of Lakshadweep is at Kavaratti island.
This land extends from below the Northern plains to South of India above Western Ghats. The erosional activity of these rives make the plateau top appear like a rolling plain. The altitudes range from 100m in the North up to 1000 m in the South. And together they from the world's largest and perhaps the most fertile delta in Indo - Bangladesh region. The Aravali hills extend from Gujarat to Delhi in a south-west to north-east direction.
