How Volcanoes are Formed - Free Essay Example

A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. The highest active volcano is Ojos del Salado. This volcano is located in South America. The effects of The volcano erupting are stuff getting burnt down and a lot of people dying because of the lava. Hawaii is one of the places to have a known volcano to erupt.
