What are ash plumes?

Ash plumes are big clouds of ash that come out of a volcano when it erupts.

Imagine you have a giant jar full of tiny bits of charcoal and sand. When the volcano erupts, it’s like someone shakes that jar really hard and throws all its contents into the air, making a big, puffy cloud. That's an ash plume!

When a volcano erupts, it sends out hot gas, rocks, and ash from deep inside the Earth. The ash is like super-fine dust made of broken-up rock and glass. It can rise really high into the sky, sometimes as high as airplanes fly!

Ash plumes can make the air look gray or even black, just like when you're cooking and smoke fills the kitchen. If you're far away from the volcano, the ash might fall back down as ashfall, covering everything in a thin layer of ash, kind of like a light snowstorm, but with tiny bits of rock instead of snowflakes.
