Volcanoes are mountains that have vents where lava sometimes flows off or just blows up.Sometimes the lava flows off when the lava increases. When 2 plates crash the magma rises quickly from the magma chamber, then it erupts.
Some volcanoes ooze lava out, and some explode. Volcanoes change land forms by adding crust and removing some land.
