Question

what is the coastal plain ​

Answer 1

$\huge\star\mathfrak\red{{Answer:-}}$

India is blessed with a long coastline extending for approximately 7500 km. It lies to the western and eastern part of the Peninsula. Its western and eastern coastlines show remarkable dissimilarities. 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. Rivers originating from 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. Because of the gentle slope of the land, rivers flow at lower velocities and deposit the sediments brought with them at the coast. As a result, deltas are found along this coast.

Answer 2

A plain adjacent to a coast is called coastal plain.
