Island

An island is a landmass entirely surrounded by water, smaller than a continent. It can form through volcanic activity, sediment accumulation, or rising sea levels. Islands vary widely in size, from tiny islets to large landmasses like Greenland. They often host diverse ecosystems, influenced by their location and climate. Islands can be inhabited or uninhabited and serve important ecological, cultural, and economic roles, such as providing habitats for unique species or supporting local communities. Their formation and characteristics are shaped by geological processes, making each island a distinct item on Earth's dynamic surface.
