Archipelago is a group or chain of islands located close to each other. These islands may be spread out or clustered together. An archipelago can include many islands of different sizes. Some are volcanic, while others are made of coral or rock.

Archipelagos are found in oceans and seas around the world, such as Indonesia in Southeast Asia. They formed over long periods through natural processes. Archipelagos can include ecosystems and human communities. Many people live across these island groups.
