UPPCS Indian Geography Gap Sheet: Islands of India.
UPPCS has asked 20 of these. 15 have not been asked yet. Lock the first list, then read the second: it holds what UPPCS has not used yet.
First, the concept
The Andaman and Nicobar Islands are the tops of a drowned mountain chain, an extension of the Arakan Yoma of Myanmar. Two of them are volcanoes: Barren (active) and Narcondam (dormant).
Lakshadweep is built of coral: 36 small islands, many of them atolls (a ring of coral around a lagoon).
Channels are named by the latitude they lie on: Ten Degree (Andaman | Nicobar), Nine Degree (Minicoy | rest of Lakshadweep), Eight Degree (Minicoy | Maldives).
