A volcano is an opening in the Earth’s crust that allows magma, hot ash and gases to escape.
Volcanoes can look like mountains or small hills, depending on what type they are.

When magma reaches the surface of the Earth it is called lava and comes out of the volcano as a volcanic eruption, along with gases and ash.
