(GEOGRAPHY)

1. Island

An island is a piece of land completely surrounded by water on all sides. Islands can be found in oceans, seas, rivers, and lakes. They vary greatly in size, from tiny uninhabited landforms to large islands like Greenland and Madagascar. Islands are formed through various geological processes such as volcanic activity, coral growth, or the separation of land from continents. Many islands have unique ecosystems with plants and animals found nowhere else. Islands are important for tourism, fishing, and biodiversity conservation. In India, the Andaman and Nicobar Islands and Lakshadweep are famous examples of island groups.

2. Peninsula

A peninsula is a landform that is surrounded by water on three sides and connected to the mainland on one side. Peninsulas often have long coastlines, making them important for trade, transportation, and fishing activities. They may be formed by geological processes such as tectonic movements, erosion, or rising sea levels. The Indian Peninsula is one of the largest peninsulas in the world and is bordered by the Arabian Sea, the Bay of Bengal, and the Indian Ocean. Peninsulas often support diverse ecosystems and large populations. Their strategic coastal location makes them important for economic and cultural development.
