A volcano is like a bottle of soda that’s been shaken up. When the pressure inside gets too high, it explodes! The Earth has hot rocks and gas deep inside, when they get pushed up to the surface, they pop out as lava and smoke.
Examples
- A soda bottle that’s been shaken up and opened suddenly erupts with fizz.
- When you blow up a balloon too much, it bursts, like a volcano erupting.
- A pressure cooker popping open is like a small volcano exploding.
