How are these fires burning underground? - Emma Bryce?

These fires are burning underground because heat and fuel stay deep inside the ground, just like when you leave your campfire going all night.

Imagine you have a big pile of leaves, logs, and dirt, that’s what's happening under the surface in some places. When there’s a fire on top, it can heat up everything below, like how your hot chocolate warms up your hands even if it’s not touching them. This heat makes the fuel underground start to burn too, but since it’s deep down, you can’t see it, just like when you hide your toys under the bed and they’re still there, even though no one can see them.

Sometimes, this underground fire is like a slow-burning candle in a dark room. It doesn't light up the whole place, but it keeps burning because there's still fuel around, like more leaves or logs hiding below. The fire moves slowly, just like how your favorite snack can last all week if you take only one piece each day.

So even though we don’t see them, these fires are quietly burning deep down, keeping warm and ready for the next big flame!
