🧠 Explanation:
An archipelago is a cluster of islands, often formed by volcanic or tectonic activity. Found in oceans like the Pacific or Indian, examples include Indonesia and the Maldives. Archipelagos support unique ecosystems and biodiversity, studied in geography and environmental science. They drive tourism and fishing economies but face challenges like rising sea levels. Their strategic locations influence maritime trade and geopolitics, as seen in the South China Sea. Understanding archipelagos highlights their ecological and economic significance, shaping policies for conservation and sustainable development in island nations and coastal regions globally.
