Answer the following in one or two sentences:

What is a Volcano? Mention its major components.

A volcano is a place where gases, ashes and/or molten rock material i.e., lava escape to the ground. The layer below the solid crust is a mantle. It has a higher density than that of the crust. It is from this that the molten rock materials find their way to the surface. The material in the upper mantle portion is called magma. When the magma is out from the volcanic mountain then it is termed as Lava. It may also happen when the plates move apart.

The volcano has the following major components. They are

• Chamber: A large pool liquid rock found beneath the crust

• Vents: It is an opening of the volcanic mountain, where the air and smoke are being out.

• Volcanic cone: it is the shape of the cone where magma is ejected from the vent.

• Carter: it is the bowl-shaped depression found at the top of the volcano
