How were the Lakshadweep Islands formed?

The Lakshadweep Islands are primarily coral atolls that originated from volcanic activity.12

According to the subsidence theory originally proposed by Charles Darwin, these islands represent the final stage of reef growth around a sinking volcanic island. As the volcanic foundation subsided over time, the coral reef continued to grow upward to remain near the surface, eventually leaving behind a ring-shaped reef that encloses a central lagoon once the volcanic peak was completely submerged.34

While the islands are of volcanic origin, their current surface features are composed of sandy soil derived from the coral. Additionally, the Lakshadweep atolls are part of the submarine Maldive Ridge, a geological structure that extends into the Indian Ocean.125
