An archipelago is a group of islands clustered together in a body of water. These islands can vary in size and shape, and they may be formed through volcanic activity, erosion, or rising sea levels. Archipelagos can be found in oceans, seas, and even large lakes, and they often host diverse ecosystems. Some well-known examples of archipelagos include the Hawaiian Islands, the Philippines, and the Galápagos Islands. These regions are significant for their unique wildlife and natural beauty, attracting tourists and researchers alike. Archipelagos can also play important roles in local cultures and economies.
