Question

how is a volcana in water formed?​

Answer 1

When the mantle rocks melt, the water dissolves into the magma. As the magma rises towards the surface and cools, pressure is reduced, crystals form and the water is released and emitted as vapour through volcanoes. ... This means there is a balance between the water in the oceans and that stored up in the mantle.
