Island is a piece of land that is completely surrounded by water. Islands can be large or small and may have mountains, forests, or beaches. Some islands are part of larger groups, while others stand alone. They can be found in oceans, seas, lakes, or rivers.
Islands are found worldwide, such as Madagascar in Africa and Japan in Asia. They formed over long periods through natural processes. Islands can support plants, animals, and human populations. Many people live on islands around the world.
