Seafloor features refer to the various geological formations found on the ocean floor. These include structures like mid-ocean ridges, which are underwater mountain ranges formed by tectonic activity, and trenches, which are deep, narrow depressions created by the subduction of tectonic plates. Other features include seamounts, which are underwater volcanoes, and continental shelves, the submerged edges of continents. The seafloor is also home to unique ecosystems, such as hydrothermal vents, where heated water supports diverse marine life. Understanding these features is essential for studying oceanography and the Earth's geological processes, as they play a crucial role in ocean circulation and biodiversity.
