The surface of the Deccan plateau slopes down from west to east. On the western side lies a range of high cliffs running south to north leaving a narrow strip pf plain between it and the sea.
It is called the Western Ghats, which rises up to 3,000 feet. The plateau is higher in the south being about 2000 feet in the Mysore region and about half of that in the Hyderabad. The Eastern Ghats, consisting of groups of low hills, is marked by several gaps through which many peninsular rivers join the Bay of Bengal.
The hills going southwards gradually receding from the sea turn westward to join the Western Ghats at the Niligiri. The plain between Eastern Ghats and the sea is wider than that of Western Ghats.
