Step-by-step explanation:
The main parts of a volcano are:
The magma chamber: is a hollow that stores the molten rock, better known as magma.
The conduit: Over there ascends the magma and the gases that will be released outward during an eruption. Volcanoes can have only one, or have several conduits.
The Vent: It is the opening in the surface of the volcano where lava and other materials are emitted. In the same way of conduits, volcanoes can have multiple vents, but there is only one main vent, this is the one that is connected to the main conduit.
The Crater: Is a bowl-shaped depression surrounding the main vent. There are formed when explosive eruptions occur.
