Okay, kiddo, have you ever seen a fire burning in a fireplace or on a camping trip? Well, imagine a really big fire burning underground in a mountain! That's what we call a burning mountain or a coal seam fire.
Now, how does this happen? You see, sometimes there are layers of coal deep below the Earth's surface. These coal layers can catch fire if they come into contact with oxygen and get really hot. This can happen naturally, like when lightning strikes, or it can happen because people have been mining coal for energy and left some underground.
When the fire is burning, it can cause the mountain to heat up and release a lot of smoke and gases. Sometimes, it can even cause the ground to crack or shift! This can be dangerous for people living nearby, so it's important that experts monitor these fires and make sure they don't spread.
Now, burning mountains might sound cool, but they're actually not good for the environment. They release a lot of carbon dioxide into the air, which is a greenhouse gas that can contribute to climate change. That's why we try to put out these fires or prevent them from happening in the first place.
