GEOLOGY

Detailed explanation-1: -Although most of the active volcanoes we see on land occur where plates collide, the greatest number of the Earth’s volcanoes are hidden from view, occurring on the ocean floor along spreading ridges.

Detailed explanation-2: -Submarine Volcano. From Hawaii to Indonesia to Iceland, hundreds of islands across the globe have been formed by submarine volcanoes. Submarine volcanoes are exactly what they sound like-volcanoes located beneath the ocean’s surface.

Detailed explanation-3: -The total number of submarine volcanoes is estimated to be over 1 million (most are now extinct) of which some 75, 000 rise more than 1 km above the seabed. Only 119 submarine volcanoes in Earth’s oceans and seas are known to have erupted during the last 11, 700 years.

Detailed explanation-4: -Also known as seamounts (underwater mountains), submarine volcanoes can be just as violent and in some cases larger than those on land.

Detailed explanation-5: -Scientists believe that 80 percent of the volcanic eruptions on Earth take place in the ocean. Most of these volcanoes are thousands of feet deep, and difficult to find. But in May of 2009, scientists captured the deepest ocean eruption ever found.
