Exploring Volcanoes

A volcano is a feature in Earth’s crust where molten rock is squeezed out onto the Earth’s surface. It is formed when molten rock, called magma, rises to the surface.

Magma is molten rock beneath the Earth's surface, while lava is magma that has erupted or flowed out of a volcano.

Volcanoes release gases, ash, and solid rock along with lava.
