Submarine Volcanism

Submarine volcanism refers to the eruption of magma beneath the ocean's surface, forming underwater volcanic features. These eruptions occur at tectonic plate boundaries and volcanic hotspots, releasing lava, gases, and ash into the ocean. As the magma cools rapidly upon contact with seawater, it creates new crust, often in the form of seamounts, mid-ocean ridges, or volcanic islands. Submarine volcanism plays a critical role in Earth's geology, contributing to seafloor spreading, influencing ocean chemistry, and creating habitats for unique marine life. Despite being hidden beneath the waves, these eruptions are vital for understanding Earth's dynamic interior.
