Why do Volcanoes Erupt? | #aumsum #kids #education #science?

Volcanoes erupt when melted rock inside the Earth pushes its way out to the surface.

Imagine you have a big jar filled with hot soup, and it's sealed tight. The soup is like magma, which is melted rock deep in the Earth. When the soup gets too hot and pressurized, it starts to bubble up, just like when you open the jar and the steam and soup rush out.

Magma moves upward because it’s less dense than the solid rock around it, kind of like how oil floats on water. As the magma rises, it can collect in a chamber, which is like a big underground bubble.

Sometimes, the pressure gets so high that the top of the volcano cracks open, BOOM! The magma rushes out as lava, and rocks, ash, and gas go flying, just like when you shake up a bottle of soda and then pop the cap off!

When this happens, it’s like a big party inside the Earth, and we get to see the fun from outside!
