Islands are a landform that can be found in oceans, lakes, and rivers. An island is an area of land not connected to a continent and completely surrounded by water.
Small islands are sometimes called cays, keys, or islets.
A group or chain of islands is often called an archipelago.
An atoll is a ring-shaped coral reef, island, or series of islets. An atoll surrounds a body of water called a lagoon. Sometimes, atolls and lagoons protect a central island
You can google more pictures of an atoll – they look pretty cool!
There are two main types of islands: continental islands and oceanic islands. Continental islands are part of a continental shelf. For example, Great Britain and Sicily are islands that sit on the continental shelf of Europe. Oceanic islands are islands that don’t sit on a continental shelf. Oceanic islands are mainly formed by undersea volcanoes like Iceland in the Atlantic and Hawaii in the Pacific Ocean.
