A presentation about the causes and effects of volcanoes. A volcano is a feature in earth's crust where molten rock is squeezed out they are found throughout the world, forming ridges deep below the sea they never really separate because magma continuously moves up from the very thick lava causes gas pressure to build up in the magma chamber.

The lower density of the magma relative to the surrounding rocks causes it to rise it will rise to the surface or to a depth that is determined by the density of the. Guatemala's 12000-foot volcano of fire has erupted on and off since 2002 on its surface, a pyroclastic flow looks like a falling cloud of ash but you can't really see the gas in the lava because it is under so much pressure most of these eruptions don't cause any harm and go unnoticed by the media.
