Three common volcano forms are: Shield volcano Shield volcanoes have a broad, flattened dome-like shape created by layers of hot and runny lava flowing over its surface and cooling. 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, …
