Answer:
A volcano is a mountain that has lava (hot, liquid rock) coming out from a magma chamber under the ground, or did have in the past. Volcanoes are formed by the movement of tectonic plates. The Earth's crust has 17 major, rigid tectonic plates. These float on a hotter, softer layer in its mantle.

Answer:
The term volcano also refers to the opening or vent through which the molten rock and associated gases are expelled. Driven by buoyancy and gas pressure the molten rock, which is lighter than the surrounding solid rock forces its way upward and may ultimately break though zones of weaknesses in the Earth's crust.
