Write the name of those islands which is formed by flow?

The Andaman and Nicobar Islands located in the Bay of Bengal is formed by flow. They are believed to be an elevated portion of submarine mountains, unlike the Lakshadweep Islands group which is believed to have been formed from coral reefs. The volcanic origin of the Andaman and Nicobar Islands is evidenced by the fact that India’s only active volcano is found on Barren island in this archipelago.
