Imagine a giant, invisible pressure cooker deep inside the Earth. A volcano erupts when this pressure cooker becomes too full and bursts open. The hot goo inside, called magma, pushes up through cracks in the ground and comes out like boiling water from a lid that’s been lifted off. This is how a volcano really erupts!
Examples
- Lava flows from a volcano just like water coming out of an overflowing tap.
