oceanic ridge

An oceanic ridge is a submerged mountain range located in the ocean, formed by tectonic plates pulling apart. As the plates separate, magma from the Earth's mantle rises to fill the gap, creating new oceanic crust. This process is known as seafloor spreading. Oceanic ridges are key features of the Earth’s geology and are home to unique ecosystems. The Mid-Atlantic Ridge is a well-known example, running down the center of the Atlantic Ocean, where it contributes to the growth of ocean basins and plays a vital role in the Earth's geological processes.
