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.
Unless the water is very shallow, the lava will quickly form a hard crust that temporarily stops the lava from moving. The lava then breaks out, crusts over again and the cycle repeats. This process forms deposits of what is called pillow lava. Over many years the rock can pile up to reach the surface of the water and form a new island.
A fringing reef (forms around an island in the tropics) forms leading to a barrier reef, to the last stage an Atoll (the island eventually disappears beneath the surface, but not the coral remains at the surface as an atoll)
It releases nutrients into the water and the lava cools. It can Also cause a tsunami. A tsunami is a giant wave that washes away entire cities. >:o
It will erupt and the lava will cool and become an igneous rock.
The Tectonic Plates rumble and can cause Tsunamis and Earthquakes. But then again, it also depends on big the volcano was, and how big of a explosion it made. :P
what happen if a volcano erupts under the sea
it creates an island usually. :)
The tectonic plates shifting is what causes an underwater volcano to erupt. Plate shifting is also the cause of tsunamis and earthquakes.
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.
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
AnswerRight now, Kiluea has erupted non-stop for at least 30 years.

because they were formed under the sea so when they erupt the can form tsunamis
Yes. If this did not happen we would not have volcanic islands.

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.
they erupt just like they do above water

No, geysers send up fountain like jets of water and steam. Volcanoes erupt lava.
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.
under water volcanoes move the oceanic plates and spread them
