Write geographical reason.
There are dissimilarities between the eastern and western coasts of India.
The western coast borders the Arabian Sea. It is by and large a rocky coast. At places, spurs taking off from the Western Ghats have extended right up to the coast. Its width is also less compared to the east coast. Rivers originating from the Western Ghats are short and swift, and hence they form estuaries and not deltas.
The eastern coast borders the Bay of Bengal. It has formed as a result of depositional work of rivers. Many east flowing rivers using from the Western and Eastern Ghats meet this coast. Since the slope of the land is gentle, rivers flow at lower velocities and deposit the sediments brought with them at the coast. As a result, deltas are found along this coast.
