Underwater volcanoes have several means of formation: so called 'hot spots' in the Earth's mantle in which case magma oozes through the oceanic crust; plate subduction, where the denser oceanic plate moves under the less dense plate and melts upon contacting the mantle, and volcanism created by diverging oceanic plates.

What causes underwater volcanoes?
the earths core ozes out magma and then throw the underwater volcano
Can volcanoes occur underwater?
Yes and a great many of the earth's volcanoes are underwater.
What happens underwater to cause a tsunami?
The most common underwater causes of tsunami are earthquakes and volcanoes. The event causes a large column of water to be displaced and moved out from the source. See the related question about the causes of tsunami for more detail about this question and about other causes of tsunami that may not start underwater.
What causes an underwater volcano erupts?
Volcanoes underwater erupt in much the same way as those on dry land. They erupt when pressure builds up. The difference between these two types of volcanoes is that the lava produced in an underwater volcano cools dramatically faster than the lava on land.
What are Underwater volcanoes called?
Underwater volcanoes are called submarine volcanoes. They form in a similar way as their continental counterparts, that is close to plate boundaries.
How are underwater volcanoes different from volcanoes that are above sea level?

How do underwater volcanoes start?
with a bang
Why are island made?
underwater volcanoes
Is forming underwater mountains and volcanoes convergent divergent or transform?
Underwater volcanoes and mountains can form at both convergent and divergent boundaries.
How do underwater volcanoes affect marine life?
Underwater volcanoes introduce substances into the water that bacteria can feed on. These bacteria are the source of nutrition for miniature ecosystems that emerge around such volcanoes.
What magma forms underwater mountains?
Volcanoes
Do people name underwater volcanoes?
Yes.
