A volcano erupts when pressure builds up inside the Earth and then suddenly escapes. Imagine a bottle of soda with a lid on it, if you shake it up, the bubbles can’t escape, but when the lid pops off, all that fizz comes rushing out in one big burst! The Earth’s lava is like that fizzy soda, and the volcano is the lid.
Examples
- When a balloon pops, it's like the rock breaking during an eruption.
