A volcano is like a mountain that can breathe fire, while a geyser is like a spring that can burst out like a fountain.
Imagine you have two friends: one is a shy kid who sometimes lets out a big shout when they’re excited, and the other is a bubbly friend who always jumps up with lots of energy. The shy kid is like a volcano, it stays quiet most of the time, but when it gets full of hot lava from deep inside the Earth, it can suddenly erupt with fire and smoke.
The bubbly friend is like a geyser, it’s always churning with water that gets heated up by the Earth. When the water gets hot enough, it pushes up through a hole in the ground, making a big splash of water and steam into the air.
How They Work Differently
- A volcano erupts because molten rock (lava) comes out from inside the Earth.
- A geyser bursts because hot water is pushed up by pressure from underground heat.
Examples
- A volcano is like a fire engine, while a geyser is like a soda bottle that pops when it gets too hot.
- Imagine a volcano as a dragon breathing fire, and a geyser as a frog jumping out of a pot.
