The correct answer is Along the Western and Eastern Ghats respectively. Important Notes: • India has a coastline of 11098.81 Indian islands] touching 13 States and Union Territories (UTs). • On the basis of the location and active geomorphological processes, it can be broadly divided into two: • the western coastal plains; • the eastern coastal plains. • Extending from the Gujarat coast in the north to the Kerala coast in the south, the western coast may be divided into following divisions – the Kachchh and Kathiawar coast in Gujarat, • Konkan coast in Maharashtra, • Goan coast and in Karnataka, • Malabar coast Kerala. • The western coastal plains are narrow in the middle and get broader towards north and south. • The rivers flowing through this coastal plain do not form any delta. • The Malabar coast has got certain distinguishing features in the form of ‘Kayals’ (backwaters), which are used for fishing, inland navigation and also due to its special attraction for tourists. • Every year the famous Nehru Trophy Vallamkali (boat race) is held in Punnamada Kayal in Kerala. • Eastern coast extends from the Subarnarekha river along the West Bengal-Odisha border to Kanyakumari. • This plain is known as the Northern Circars between the Mahanadi and the Krishna rivers and Carnatic/Coromandel between the Krishna and the Cauvery rivers. • As compared to the western coastal plain, the eastern coastal plain is broader and is an example of an emergent coast. • There are well developed deltas here, formed by the rivers flowing eastward in to the Bay of Bengal. • These include the deltas of the Mahanadi, the Godavari, the Krishna and the Kaveri. • Because of its emergent nature, it has less number of ports and harbours.
