Oil sands are deposits of a dark, thick, sticky substance called bitumen. Bitumen is a kind of oil that is trapped in rocks and sand. It looks a bit like mud or peanut butter. People use oil to make things like gasoline, plastic, and makeup.
Getting oil from oil sands is tricky. First, workers have to dig a big hole in the ground to get to the oil sands. Then they scoop up the sand and put it in a big truck. They mix the sand with hot water to separate the bitumen from the sand.
After that, they use big machines to turn the bitumen into a kind of liquid oil. Then, they put it in trucks and take it to a factory where they clean it up and turn it into usable oil products.
Oil sands are important because they have a lot of oil - more than most places in the world. But it can harm the environment because getting the oil can cause pollution and harm to animals and plants.
