The Eastern Ghats is an irregular range of mountains cut through by the four major rivers the
Godavari,
Mahanadi,
Krishna, and
Kaveri. It broadly covers three regions, the southern Orissa highlands,
Chittoor and
Cuddapah districts of the Rayalaseema region in
Andhra Pradesh and the uplands and the
Nilgiri region of
Tamil Nadu. The hill ranges of
Cuddapah District in the Rayalaseema region form the central portion of the Eastern Ghats.
The average elevation of the range is about 600 m. The maximum elevations are at the northern and southern ends. This ghat parallel to the Bay of Bengal is not as high as the Western Ghats.
