What is the name of the mountain range that is on the bottom of the ocean?

The largest and best known undersea mountain range is a mid-ocean ridge, the Mid-Atlantic Ridge. It has been observed that, “similar to those on land, the undersea mountain ranges are the loci of frequent volcanic and earthquake activity”.

What is a volcanic mountain that rises above the surface of the water?

an island that is the top of a volcano that extends above the surface of the sea. seamount. A volcanic mountain rising from the floor that doesn’t reach the surface.

How many mountains are underwater?

What are undersea mountains called?

A seamount is an underwater mountain. A rise is an underwater mountain range located where tectonic plates are spreading apart. A rise is also known as a mid-ocean ridge.

Why are undersea mountains flat?

When an undersea volcano grows high enough to be near or breach the ocean surface, wave action and/or coral reef growth tend to create a flat-topped edifice. In addition, the erosive effects of waves and currents are found mostly near the surface: the tops of guyots generally lie below this higher-erosion zone.

Where are the mountains of the deep sea?

By: Eva Gruber. Entire mountains and mountain ranges lay submerged beneath the surface of our oceans. These underwater mountains, called seamounts rise thousands of feet from the sea floor, and stand waiting, as they have for millions of years, to be explored.

Are there mountains that broke the surface of the Earth?

If they broke the surface, they would be islands much like Hawaii or the Aleutian Islands. In fact, the highest mountain on Earth, Mauna Kea, was a seamount that broke the surface and now makes up the Big Island of Hawaii.

Are there any volcanoes that broke the surface?

Many of them are actually extinct volcanoes. If they broke the surface, they would be islands much like Hawaii or the Aleutian Islands. In fact, the highest mountain on Earth, Mauna Kea, was a seamount that broke the surface and now makes up the Big Island of Hawaii.
