The diagram below shows the formation of a supervilcano and the stages involved. Summarise the information by selecting and reporting the main features, and make comparisons where relevant. Write at least 150 words.

The diagram illustrates a process, which includes four stages, of how supervolcanoes are formed. It is shown, that Earth has a layered structure that consists of mantle,

magma

and

crust

. The formation begins when

magma

fills the hole in the

crust

, which is called a

remained untouched. After

magma

takes up all the space in the

magma

chamber it still proceeds to flow from underneath, exerting great pressure on the

crust

and that in terms causes fissures to form. Moving on to the next stage,

magma

is pushed out with a huge speed through the cracks in the

crust

right to the surface, where lava and smoke make their way out and cause volcanic eruptions.
