A volcano is a crack or opening in Earth’s outermost crust where molten rock called magma and gases can escape, spilling or falling to the surface. Geologists generally group volcanoes onto a spectrum of behavior that can be summed up by four principal types: cinder cones, stratovolcanoes, shield volcanoes and lava domes. Let's take a peek at each one.
