What are explosive eruptions?

Explosive eruptions are when a volcano blows up really hard, sending out lava, rocks, and ash high into the air.

Imagine you're blowing up a balloon with your mouth, it gets bigger and bigger until BOOM! it bursts. That’s like an explosive eruption. The balloon is like the inside of a volcano, filled with hot gases and rock. When the pressure gets too much, everything comes rushing out in a big, loud explosion.

Inside a volcano, there's lots of magma, that’s hot, melted rock. Sometimes, gas builds up inside the magma, like air trapped in a soda bottle. When the gas suddenly escapes, it pushes the magma and rocks out with whoosh!, that’s the eruption.

After an explosive eruption, you might see ash falling from the sky, like snow but black. Big pieces of rock can fly far away, and sometimes even lava comes pouring out. It’s a real-life version of a firework show, just way bigger and messier!
