underwater volcano
Seafloor magma vent
An underwater volcano is a volcanic vent or mountain on the ocean floor that erupts magma into the surrounding water.
Most volcanic activity on Earth occurs underwater along mid-ocean ridges, where tectonic plates spread apart.
When underwater volcanoes build up enough material to break the surface, they form volcanic islands: The Hawaiian islands were created by underwater volcanoes.
