Crude Oil is a product that is found in the sea. Crude Oil is found in the Earth's crust. Millions of years ago small animals and plants died and fell to the bottom of the sea. Their remains were covered by mud.
Other rocks above the oil were impermeable. The oil could not float upwards through these rocks and so it gets trapped underneath it. Geologists - rock scientists - can often tell where oil may be trapped.
Oil companies can drill down through the impermeable rocks to get it out. They are then able to turn it into products we can use.
Materials like crude oil and coal which formed from living things many years ago are called fossil fuels. Crude oil takes millions of years to form, so when we have used it all, we cannot quickly get more.
This is why we call crude oil a non-renewable or finite resource.
Our supplies will run out in about 50 years' time.
