This gap, which completely intersects the Ghats, is about 20 m.
The Eastern Ghats have an average elevation of 1500 ft.
On the eastern side of India, the Ghats form a series of spurs and buttresses for the elevated inner plateau, rather than a continuous Eastern mountain wall.
They are traversed by a number of Ghats.
The drainage has therefore to make its way across India to the eastwards, now turning sharply round projecting ranges, now tumbling down ravines, or rushing along the valleys, until the rain which the Bombay sea-breeze has dropped upon the Western Ghats finally falls into the Bay of Bengal.
