how are volcanoes formed?

Volcanoes are formed when the mantle (a thick layer of solid rock under the surface of the earth) melts into liquid magma and rises to the surface.
When the magma rises it erupts through cracks between the tectonic plates becoming lava.
Also, there are hotspots in the middle of some tectonic plates causing pieces of the mantle to rise up above the surface. When this happens sometimes the center of the pieces melt into magma forming a volcano.

What causes volcanoes to erupt?
