Volcanos

Volcanoes are located at the edge of tectonic plates. Volcanoes are made when two plates move away from each other leaving an opening. Or two plates could collide causing one to go underneath another. only a few are formed like this but those are the most destructive.

The magma, which is called magma on the surface comes from the mantle. The earth has three layers, the core, the outer core and the mantle. The outside is the crust. The magma gets out by finding cracks in the crust and pushing up. Active volcanoes are dangerous and could erupt at anytime. Dormant volcanoes are volcanoes that haven't erupted for a long time but there is still a chance. After 10 000 years of no activity the volcano is then extinct.
