How Volcanoes Work?

Volcanoes are vents in the Earth's surface where hot molten rock (magma), ash, and gases come out. They work by magma building up pressure beneath the Earth's crust, causing it to rupture and release the magma and gases. This eruption can release lava or ash, which can be dangerous to people and the environment. Volcanoes are formed by the movement of tectonic plates or hotspots in the Earth's mantle.
