7. Structures of Volcano

8. Other Geologic features of a
volcano:
•Magma Chamber is a region beneath the vent of a
volcano where molten rock or magma is deposited or
stored before eruption.
Main Vent is the main opening or outlet on the
surface of a volcano that emits lava, gases, ash or
other volcanic materials.
Conduit is an underground central tube-like or
pipe-like structure of a volcano that connects the
magma chamber to the crater through which the
magma travels.

9. •Side Vent is a smaller outlet through
which magma escapes.
•Crater is the mouth of the volcano which
is a funnel-shaped or bowlshaped hollow
at the top of the vent from where magma,
ash and gas comes out.

10. •Lavais a molten rock which is given off
onto the surface of the Earth when a
volcano erupts.
•Ash and Gas Cloud is a of mixtures of
rock, minerals, glass particles and gases
expelled or pushed out of the volcano
during volcanic eruption.
