A volcano is an opening in the surface of the Earth from which hot magma flows out. The following are the structural features of a volcano: Vent: It is an opening from which hot magma flow out to the surface of the Earth. It is a circular pipe-like structure. Crater: It is a bowl-shaped opening or a mouth of a volcano. Magma chamber: It is here that the hot magma is stored beneath a volcano.
