Volcanoes
Volcanoes are formed by a fissure in the earth's crust through which molten lava and gases erupt. These formations are usually found on diverging or converging tectonic plates or above mantle plumes, in places called hotspots. There are numerous types of volcanoes: fissure vents, shield volcanoes, cinder cones, stratovolcanoes, cryptodomes, submarine volcanoes, supervolcanoes and many more.
On a climate change scope, man-made emissions can make the consequences of volcanic eruptions much more severe.
