An archipelago is a group or chain of islands that are clustered together in a body of water. These islands can vary in size and can be found in oceans, seas, or lakes. Archipelagos can be formed through volcanic activity, erosion, or rising sea levels, and they often host unique ecosystems and diverse wildlife. Some well-known examples of archipelagos include the Hawaiian Islands, the Philippines, and the Aegean Islands. Each of these groups of islands has its own distinct geography, culture, and history, making them popular destinations for tourism and study. Archipelagos can also play important roles in maritime navigation and trade.
