A volcano erupts when pressure builds up inside it. Imagine a soda bottle that’s been shaken and capped, when you open it, the soda explodes out because of all the bubbles. A volcano is like a giant soda bottle full of hot rock and gas. When the pressure becomes too much, poof! The lava, ash, and smoke shoot out into the air.
Examples
- A soda bottle exploding after being shaken is like a small volcano erupting.
- A lava lamp bubbling and rising shows how hot rock can move inside the Earth.
