Volcanoes
Why did volcano erupt? Hot lava erupted out from the Earth up to the Earth surfaces. Actually this lava is hot melted rock called magma. It’s just underneath the Earth crust is a layer called the mantle, which is made out of plates that are always moving. Sometimes it’s separate. That makes heat and causes the mantle to melt the magma. The magma comes up through the crack between the plates. It spreads out and cools down and it becomes rock again. The solid magma stays beneath the Earth surfaces.
