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. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, … WebA volcano is a vent in the earth crust that lets out hot lava, gasses, rocks, volcanic ash and steam from a magma chamber underneath the earth’s surface.
