Why does Volcanoes erupt?
There is a layer called the mantle underneath the Earth's crust. The mantle is made of up plates that are always moving and shifting. When the plates separate, it creates heat and causes the mantle to melt into magma. The magma comes up through the crack between the plates. The magma pushes upward, melting more rock. The hot magma collects under the surface of the Earth. If the pressure is high enough or a crack opens in the crust, the magma spews out.
