What is Peninsula?

From the plains of Ganga and the Indus by a mass of mountains and hill ranges varying from 460-1220m in height, the Peninsula Plateau is marked off. The prominent among them are Aravalli, Vindhya, Satpura, Maikala and Ajanta.  The Deccan plateau (the Peninsula shield) is flanked on the east by Bay of Bengal and Eastern Ghats with an average height of 610m and on the west by Arabian Sea and Western Ghats with a height of 915-1220m (rising in some places to 2440m). Nilgiri Hills is the southern point of the plateau and the meeting place of both the Ghats.
