Scientists define an active volcano as one that has erupted in the last 10, years. Based on this definition, the earth has around 1, active volcanoes spread across the globe.
Around 75 percent of those are located along the pacific ring of fire — a region that spans the perimeters of landmasses on the Pacific ocean. All volcanoes form through the basic process of magma working its way up through the earth's mantle and crust. As the magma works its way through to the surface, it eventually breaches and starts to harden. This hardening of magma over and over causes the formation of a taller or wider volcano. The source of this magma comes from deep within the earth.
It's so hot near the earth's core that rocks melt and become a thick flowing substance, what we know as magma. As the rocks melt into magma, its density actually changes to become lighter than the solid rocks around it.
This causes the magma underground to rise like bubbles in the water. This magma rises under the earth's harder rock layers, collecting in magma chambers. When the rock strata under the crust of the earth is weaker in certain areas, the magma can heat through these different pathways creating lava tubes and fissures, often all the way up to the surface.
Where the underground magma breaks through the surface, an eruption occurs. Some eruptions are explosive while others ooze slowly out.
This is due to caps being formed over time, where lava seals off a particular magma tube, only for pressure to build up and eventually cause an explosion.
