Hey mate, here is your answer :

Although there are several factors triggering a volcanic eruption, three predominate: the buoyancy of the magma, the pressure from the exsolved gases in the magma and the injection of a new batch of magma into an already filled magma chamber.

Answer 2

when we study about our earth then we find that , in our earth crest many types of plates are present which further breaks and form tectonic plates . due to high temperature of heat the gases are formed and it makes high pressure. The pressure formed inside the earth crust want to come out then it found the way where the soil means plates are loosely packed. like inside oceans. so it comes out from the earth crust .
when volcano come on that time many metal from the earth crust come outside.
it also a reason for the waves of our oceans.
