A seamount is an underwater mountain that rises from the ocean floor but does not reach the water's surface. These geological formations are typically formed by volcanic activity and can vary in height and shape. Seamounts are often found in chains or clusters and can be significant for marine ecosystems, providing habitats for various marine life. Seamounts can influence ocean currents and nutrient distribution, making them important for fishing and biodiversity. They are often associated with other underwater features, such as ocean ridges and trenches, and can be found in all of the world's oceans, contributing to the complexity of oceanic landscapes.
