A volcano is an opening, or rupture, in a planet’s surface or crust, which allows hot magma, ash and gases to escape from below the surface.

There are different types of volcanoes.

  • Composite volcano or stratovolcano: is a tall, conical volcano built up by many layers (strata) of hardened lava, tephra, pumice  and volcanic ash. Stratovolcanoes are characterized by a steep profile and periodic, exp0losive eruptions.

  • Shield volcano: s a type of volcano built almost entirely of fluid lava flows.

And remember, be free as the volcanoes.
