Science: Hazard Research - Volcanoes

Volcanoes created more than 80 percent of the earth's surface, laying that foundation that allowed life to thrive. their explosives forces crafted mountains as well as craters. lava rivers into the bleak landscapes of earth. but as time flies by, the elements break down these volcanic rocks, liberating nutrients from their stone prisons and creating fascinating fertile soils that had allowed civilization to burst into existence. volcanoes are located everywhere, even in the Antarctic one of the coldest places on earth. some of the 1,500 volcanoes are still considered potentially active around the whole world today.

Most of the majority of the volcanoes in the world form along the boundaries of the planet's tectonic plates. tectonic plates are massive expanses of earth lithosphere which constantly shifts, as the plates bump into each other. when the tectonic plates collide, one often sinks deep below which is also known as the subduction zone. magma is formed by the descending landmass sinking while the pressure and temperatures climb, releasing water from rocks. The water slightly reduces the melting point of the overlying rocks, this forms magma. As magma climbs its way to the surface, the spark of life to reawaken a slumbering volcano.

The are two types of volcanoes are split into different groups, by eruption type and their volcanic shape.  there are there basic cone shapes. Cinder cones, shield cones, and composite also know as stratovolcanoes
