yes most volcanos start under water as over 70% of the earth is water from soulesance =D
No, they are under water but not under ground. There is no ground above them.
a volcano that starts and erupts under water
if you are right above it properly yes but if you at the surface of the water it would have cooled down by the time it gets to you
It could be land masses that were already there, it doesn't always have to volcano made. Or, It could be land that was under ground that was exposed when water levels went down
ummm neither.... they live under water..............
a volcano
the term for under water is ''ground water ''.
ground water
land
A seamount.
So that the water doesn't drain out of the pool and so the pool doesn't fall over. I agree with the answer above but I have a more detailed answer. In a round above ground pool the water puts even pressure on the pool walls, and if the ground is not level one side will get more pressure. The imbalance will cause the pool to collapse under the strain.
When techtonic plates collide and go apart magma from the mantle come up to the crust. Then after a long time of that happening the lava cools and forms new ground which builds up into a volcano. A volcano could be on land or under water.
