– The Andaman & Nicobar Islands are primarily island arcs formed by the collision of the Indian and Burmese tectonic plates (part of the Sunda Arc). While volcanic activity exists in the region (e.g., Barren Island, Narcondam Island), the archipelago as a whole is not solely of volcanic origin in the same way as a hotspot island like Reunion.
– Lakshadweep Islands and Maldives are coral atolls, formed on submerged volcanic foundations but the visible landmass is due to coral growth.
