Sea mounts are underwater mountains formed by volcanic activity. They rise from the ocean floor but do not reach the water's surface. These geological features can vary in height and size, and they often create unique ecosystems that support diverse marine life. Many sea mounts are hotspots for biodiversity, attracting fish, corals, and other organisms. They provide habitats and feeding grounds, making them important for both ecological balance and fishing industries. Some well-known sea mounts include the Hawaiian Islands and the Mid-Atlantic Ridge, which are significant for their geological and biological importance.
