(i) The eastern coast borders the Bay of Bengal. It has been formed as a result of depositional work of rivers.
(ii) Many east flowing rivers rising from the Western and Eastern Ghats after travelling a long distance join the Bay of Bengal at this coast.
(iii) Because of the gentle slope of the land, rivers flow at lower velocities and deposit the sediments brought with them at the coast.
Therefore, this coast is comparatively wider than the west.
(iv) As a result, deltas are found along the eastern coast of India.
