Seamount! how much of the mountain can you really sea?

Seamounts are underwater mountains that rise hundreds or thousands of feet from the seafloor. They are formed by volcanic activity and once thought to be nothing more than hazards to submarine navigation. Nutrients are carried up from the depths of the oceans toward the surface, which then provides food for creatures ranging from corals to fish to crustaceans.

They are commonly found near boundaries of Earths tectonic plates and mid plate near hotspots.

Seamounts encompass about 28.8 million square kilometers of the Earth's surface.

They are generally extinct volcanoes that created piles of lava that sometimes break the ocean surface.

The highest mountain on Earth is a seamount- Hawaii's Mauna Kea, a dormant volcano that is more than 30,000 feet tall measured from its base on the seafloor 18,000 feet beneath the surface.

Seamounts attract an abundance of marine life and are productive fishing grounds more than 80 commercial species worldwide.
