                                           Facts about Volcanoes

Volcanoes can be defined as openings in the earth’s surface from which gas, hot magma, and ash can escape. The term volcano has been derived from the Roman name ‘Vulcan’ who is the Roman god of fire. Volcanoes are generally found at meeting points of tectonic plates. There are mainly four types of volcanoes which are Shield Volcano, Composite Volcano, Cinder Cone, and Lava Dome. The hot liquid rock is known as magma when it is inside the volcano and known as lava once it leaves the volcano. Common volcanic gases are water vapor, carbon dioxide, hydrogen chloride, sulfur dioxide, hydrogen sulfide etc.
