mid-ocean ridge
Sea floor spreading causes several chains of underwater mountains. They are sometimes called seamounts. They are also called mid ocean ridges.
A massif
Underwater mountains are called seamounts. They are elevated underwater mountains that do not reach the water's surface. Seamounts are formed by volcanic activity or tectonic forces and can support diverse marine ecosystems.
Underwater mountains that rise above the surface of the water are called islands. These formations are the result of volcanic activity or tectonic movements that cause them to breach the water's surface.
The tallest underwater mountains in the world are called seamounts. They can be found in all of the world's oceans, with some of the largest concentrations in the Pacific Ocean.
Mountains and hills underwater can be bigger than the mountains and hills on land.
underwater peak with round or irregular top
Underwater mountains, also known as seamounts, are volcanic formations that rise from the seafloor. They provide a unique habitat for a diverse range of marine life due to their topographical complexity. Seamounts can also influence oceanic currents and nutrient cycling in the water column.
Underwater volcanoes and mountains can form at both convergent and divergent boundaries.
