== Underwater volcanoes are formed at 'hot spots' in the Earth's mantle, as in the Hawaiian Island chain, or in deep sea trenches, where oceanic crust is subducting under oceanic crust, melting when it reaches the mantle, then erupting as a volcano.

∙ 10y agoMost of the time, underwater volcanoes are created due to a subduction zone. A subduction zone is where two convergent plates come together and the denser one ends up being slid underneath the other plate. Because of this, as the denser plates gets closer and closer to the mantle, the crust starts to melt, creating magma. This magma floats up and creates volcanoes, under and above the water.

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.
ARE volcanoes found only in islands?
No, some volcanoes are underwater and when they erupt the magma gets higher and higher and forms on the ocean which is land. (that is how Hawaii was made)
Is forming underwater mountains and volcanoes convergent divergent or transform?
Underwater volcanoes and mountains can form at both convergent and divergent boundaries.
Why does magma aften form at the boundary between separating tectonic plates?
It is because volcanoes form by two tectonic plates which when both collide and they form volcanoes which a magma rock forms when it explodes.
What is the difference between Compare volcanoes that form on land with volcanoes that form in the ocean.?
Land Volcanoes eat lamas and underwater volcanoes eat camals
What magma forms underwater mountains?
Volcanoes
What causes underwater volcanoes?
the earths core ozes out magma and then throw the underwater volcano
When does magma form?
when volcanoes erupt
How do they Hawiians Island form?
Underwater volcanoes
How do under water volcanoes explode?
When tectonic plates meet underwater. They crash into eachother and the magma underneath comes out and an underwater volcano starts.

Will the sea drain away in an underwater volcanic eruption?
No, because as the magma rises from underwater volcanoes it heats the water causing it to rise. The magma then solidifies. Therefore when the volcano is active it is always heating the water around it. When the magma stops flowing then the volcano will solidify.
Why are there no volcanoes in chelmsford?
There are no volcanoes in chelmsford because it isn't on the edge of a technonic plate so the magma can't escape to form volcanoes.
