Coastal Plains & Island Groups of India GK Questions & Answers
India's coastline spans 7,516.6 kilometres, bounded by distinct Western and Eastern Coastal Plains and two major offshore archipelagos. The Western Coastal Plain is a narrow, submerged littoral strip between the Western Ghats and the Arabian Sea, divided into the Konkan Coast (Maharashtra-Goa), Kanara Coast (Karnataka), and the Malabar Coast (Kerala), the latter famous for backwater lagoons termed 'kayals', notably Vembanad Lake. Conversely, the Eastern Coastal Plain represents an emergent coastline characterized by broad, fertile deltas formed by the Mahanadi, Godavari, Krishna, and Cauvery rivers. It is physiographically divided into the Northern Circars in the north and the Coromandel Coast in the south, hosting significant brackish water bodies like Chilika Lake and Pulicat Lake. Offshore, the Andaman and Nicobar archipelago in the Bay of Bengal comprises over 500 islands of volcanic and tectonic origin—representing the submerged extensions of the Arakan Yoma range—where the Ten Degree Channel separates the Andaman group from the Nicobar group, and Barren Island hosts South Asia's only active volcano. In the Arabian Sea, Lakshadweep constitutes 36 coral atolls governed from Kavaratti, divided by the Eight Degree and Nine Degree Channels.
