How do volcanoes happen?

Peoples quotes: "Deep below the Earth's crust, the temperatures and pressures are great enough to melt rock. When this molten rock blasts to the surface, the result is a volcano - and for the inhabitants of the place, it's as if Hell has been let loose." (Natural Disasters, Readers Digest,1996)
