As the lava or magma rises up to the surface, it cools. Thus, causing the hot lavaor magma to cool and start to harden. As it starts to harden it leaves a trail from bottom to top of the ocean or sea of which it is in. When it is at the top of the surface it forms a big mound or pile of lava or magma. As this mound cools and the lava or magma keeps building up, the trail settles to the bottom of the sea or ocean. When it finally sinks to the bottom, and you can see it, it has formed an island.

How can volcanoes errupt under water?
Volcanoes can erupt underwater when magma rises to the surface through a weak spot in the Earth's crust on the ocean floor, known as a mid-ocean ridge or a hotspot. When the magma reaches the cold ocean water, it can cause the water to heat up rapidly, leading to explosive eruptions and the formation of underwater volcanoes.
Are all volcanoes destructive?
Volcanoes are only destructive to people and property when they erupt. Volcanoes can lie dormant for decades before they erupt. The Hawaiian Islands were all formed from eruptions of volcanoes in the ocean.
Can a volcano erupt under water?
The tectonic plates move under the earth causing an eruption. This is the same basis for both under water and above water volcanoes. These volcanoes are officially called submarine volcanoes. They account for 75% of all magma produced by volcanoes. AND BOOOOOM
Under water volcano?
One of the most active areas for volcanoes found under the sea is known as Pacific Rim of Fire. This area has many volcanoes that could have a devastating effect if they erupt on areas including the Philippines.
Are there any volcanos under water?
Yes, there are underwater volcanoes known as submarine volcanoes. These volcanoes are located on the ocean floor and can be active, creating new seafloor as they erupt. They are often associated with mid-ocean ridges and subduction zones.
Why do some volcanoes erupt in under water?
because they were formed under the sea so when they erupt the can form tsunamis
Can volcanoes erupt under water?
Yes. If this did not happen we would not have volcanic islands.

How long has ocean pollution been around?
As long as there has been an ocean. Some pollution happens without the assistance of mankind. That includes volcanoes that erupt underwater, and oil deposits that leak out of the ground under or near water.
How do underwater volcanoes erupted?
they erupt just like they do above water
Are geysers volcanoes?
No, geysers send up fountain like jets of water and steam. Volcanoes erupt lava.

What happens in sea floor spreading?
under water volcanoes move the oceanic plates and spread them

How can a volcano erupt under the ocean?
A volcano is not like a forest fire. Oceans have no affect on volcanoes. The heat within the Earth that drives volcanoes is too great to be extinguished by surface water. See related link for video.
