It releases magma and starts melting/burning the earth until it cools down.
Lava that does not leave the volcano during an eruption and stays under the surface creates pressure on the walls of the volcano. These bulges increase the size of the volcano.
They both change the Earth's surface quickly
it is side vents
people died when they happen
Lava
the earth's surface as a continental drift
magma flows up to form the eruption
Temperature is constant during a phase change.
A Magma Chamber is a space (that can change size) at a depth below a volcano in which magma can accumulate prior to an eruption. A volcanic vent is a conduit connecting the magma chamber to the surface. It is though this that the magma flows during an eruption.
During the more violent eruptions, pieces of the rim of the volcano can break away, changing the shape of the volcano.
The surface thaws out a bit.
