Islands and Archipelagos

Islands are land masses surrounded by water, while archipelagos are groups of islands clustered together. These geographical features can be formed by volcanic activity, erosion, or the rising of land above sea level.

Islands can be large, like Greenland, or small, like the many tiny islands in the Caribbean. Archipelagos, such as the Hawaiian Islands, provide diverse habitats for plants and animals, showcasing unique ecosystems due to their isolation.
