An undersea mountain range, or mid-ocean ridge, refers to a series of underwater mountains formed by tectonic plate movements and volcanic activity along divergent plate boundaries. These ranges are typically characterized by a continuous ridge of underwater volcanoes and are often shaped by the process of seafloor spreading, where magma rises from the mantle to create new oceanic crust.
