How are volcanoes formed?

Volcanoes are formed when molten rock, called magma, rises to the surface of the Earth. This magma is generated by the melting of rocks in the Earth's mantle. As the magma rises, it can create cracks and weak spots in the Earth's crust, allowing it to reach the surface. Once the magma reaches the surface, it is called lava and it erupts, forming a volcano.
