Imagine a volcano is like a giant pressure cooker. When hot rock melts and becomes lava, it builds up inside the volcano like steam in a pot. Eventually, the lid pops off with a big Boom!, that’s an eruption! The loud noise happens because the air gets pushed out really fast, making a sound like a shout from deep underground.
Examples
- A pot of boiling water on a stove hissing loudly when it starts to overflow
- A balloon popping with a loud snap! after being stretched tight
- Thunder during a storm, which is caused by the rapid expansion of hot air
