These are narrow coastal strips, running along the Arabian Sea on the west and Bay of Bengal on the east.
These are known as western coast and eastern coast of the coastal plains.
The western coast is sandwiched between the Western Ghats and the Arabian Sea.
It is a narrow plain and consists of three sections. The northern part of the coast is called the ‘Konkan’, the central is called ‘Kannad Plain’ and the southern part is called the ‘Malabar Coast’.
The plains along the Bay of Bengal are wide and level.
In the northern part, it is called Northern Circas, while the southern part is known as Coromandal Coasts.
Large rivers such as the Mahanadi, the Godavari, the Krishna and the Kaveri form extensive deltas on the eastern coasts.
Lake Chilika is also located on the eastern coast. It is the largest salt water lake of India.
