An islet is a small island, often found in oceans, lakes, or rivers. These tiny landforms can be uninhabited and are usually covered with vegetation or rocks. Islets can be formed through various natural processes, such as volcanic activity or the accumulation of sand and sediment. They often serve as habitats for wildlife, including birds and marine creatures. Many islets are part of larger ecosystems and can be important for biodiversity. For example, the Galápagos Islands are famous for their unique islets that support various species, contributing to the study of evolution and ecology. Islets can also be popular destinations for tourists seeking adventure and natural beauty.
