What typically escapes from a volcano?

Volcanoes are ruptures in the Earth's crust that allow hot, molten rock, ash, and gases to escape from below the surface. They are often found where tectonic plates are diverging or converging. The study of volcanoes, called volcanology, has greatly enhanced our understanding of Earth's interior and geological processes.
