A submarine mountain, also known as a seamount, is a large underwater topographic feature that rises from the ocean floor and reaches the surface. Seamounts can take different shapes and sizes, and they are often associated with volcanic activity. Other synonyms for submarine mountains include undersea mountains, oceanic mountains, and bathymetric ridges. Some seamounts are even more specific in their names, such as guyots, which are seamounts with a flat top, and tablemounts, which resemble a plateau. Seamounts are fascinating and important geological structures that contribute to the ocean's diversity and play a crucial role in supporting marine ecosystems.
