Describe the stages of a volcanic eruption from the formation of cracks in the earth’s crust to the outpouring of lava.

Before the start of a volcanic eruption, volcanic earthquakes occur and cracks form in the earth’s crust. The eruption begins with the release of gas, volcanic ash and volcanic bombs. Along the cracks and through the crater of the volcano, magma rushes upward with force – a complex composition of fiery liquid melt of substances from deep layers. The magma poured onto the surface of the Earth is called lava. Lava quickly cools down, turning into solid rock.
