Volcanoes
A volcano is an opening in Earth's crust where melted rock, called magma below ground and lava once it reaches the surface, can escape along with gas and ash, sometimes gently and sometimes in a violent eruption. Most of the world's active volcanoes, about three out of every four, are found along the Pacific Ring of Fire, a horseshoe-shaped belt where several tectonic plates meet.
