What is an underwater mountain formed by a volcano?
Furthermore, how are underwater volcanoes formed?
The way that underwater volcanoes are formed, is very similar to the ones on dry land. Normally, underwater volcanoes form near the tectonic plates. The pressure of the magma builds up and when it finds a weak spot on the crust, it rips it open and starts an eruption.
Furthermore, what is an underwater mountain range called? Undersea mountain ranges are mountain ranges that are mostly or entirely underwater, and specifically under the surface of an ocean. In contrast, if formed by past above-water volcanism, they are known as a seamount chain. The largest and best known undersea mountain range is a mid-ocean ridge, the Mid-Atlantic Ridge.
Keeping this in view, what is a seamount and how is it formed?
They are formed primarily by rapid undersea buildups of basalt, a dark, fine-grained rock that is the main component of the ocean's crust. Seamounts form by submarine volcanism. After repeated eruptions, the volcano builds upwards into shallower water.
Can volcanoes exist in the ocean?
The greatest number of the Earth's volcanoes occur on the ocean floor. ROV Jason gets a close view of magma explosions and lava flows on West Mata volcano. Volcanic eruptions occur only in certain places and do not occur randomly.
