Explanation: Lakshadweep is a group of islands located in the Laccadive Sea off the southwestern coast of India, specifically off the coast of Kerala. The islands are part of the Indian Union Territory of Lakshadweep and are known for their unique geographical features and ecological significance.
The formation of the Lakshadweep Islands is a fascinating process that involves the growth of coral reefs over a long period. Coral atolls are ring-shaped coral reefs that encircle a lagoon. They are formed when coral polyps grow on the submerged edges of a volcanic island or seamount. Over time, the central volcano may subside or erode, leaving the coral reef as the only visible structure above the water. This process can take thousands of years, and the resulting atoll is a unique ecosystem that supports a variety of marine life.
In contrast, volcanic islands are formed by the eruption of volcanoes, either on land or underwater. The lava and ash from these eruptions can build up to form islands. Examples of volcanic islands include the Hawaiian Islands and the Galápagos Islands. The misconception that Lakshadweep is of volcanic origin might arise from the general association of islands with volcanic activity, but this is not the case for Lakshadweep.
The other options in the question are correct and refer to specific mountain ranges and their highest peaks in India. The Western Ghats, Eastern Ghats, and Nilgiris are all significant mountain ranges in India, each with its own unique geological and ecological characteristics. Anamudi peak in the Western Ghats, Aroma Konda in the Eastern Ghats, and Doddabetta in the Nilgiris are the highest peaks in their respective ranges and are well-known geographical landmarks.
Understanding the formation processes of different geographical features is crucial for comprehending the diverse landscapes of India and the world. The distinction between coral atolls and volcanic islands is particularly important in the context of Lakshadweep, as it highlights the unique geological processes that shape our planet's surface.
