Fracking, or hydraulic fracturing, is a way to get natural gas and oil out of the ground. It's like when you squeeze a juice box to get all the juice out.
First, people drill down into the ground, really deep, like playing Minecraft, but in real life. When they reach the layer of rock underground that has gas or oil trapped in it, they make a hole in it.
Then they pump water mixed with sand and chemicals (like soap or disinfectant) into the hole at really high pressure to help crack or break the rock open. Kind of like blowing up a balloon until it pops. This is called "fracking."
The sand helps to keep the cracks in the rock open, so the gas or oil can flow out. The chemicals help to clean the gas or oil and stop bacteria from growing inside the well.
Finally, the gas or oil is pushed up through the well to the surface, where it can be collected and used for things like heating homes or powering cars.
Overall, fracking is a way to get more natural gas and oil out of the ground, which can be useful for our daily needs, but it also has some risks to the environment and people's health if not done carefully.
