What are stratovolcanoes?

A stratovolcano is a big mountain made from layers of rock and ash that pile up over time.

Imagine you're building a tower out of blocks, some are small, like the ones you use to make your house, and others are bigger, like the ones you stack high. A stratovolcano works kind of like that, but instead of blocks, it uses lava, ash, and rock from big eruptions.

Every time a stratovolcano erupts, it sends out hot lava and clouds of ash. These materials cool down and harden, creating new layers on top of the old ones, just like adding another floor to your block tower. Over thousands of years, these layers build up, making the mountain taller and steeper.

Think about a stratovolcano like Mount Fuji in Japan or Mount St. Helens in the United States. These mountains look smooth from far away, but if you get close, you can see the different colors and textures of the layers, just like how your block tower might have different colored blocks stacked on top of each other.

Stratovolcanoes are like nature's slow-motion building project, one layer at a time!
