WATCH: How does a volcano explode?
Have you ever wondered exactly how a volcano explodes?
Magma flows 2900 km below the earth’s surface. Cracks in the earth’s crust allows magma to rise closer to the surface, creating magma chambers.
When these chambers are full, magma climbs up vents of the volcano. Gasses then build up and create volcanic explosions.
While volcanoes are dangerous, they play a vital role on earth.
