Q

How is crude oil made?

A

Example:
There are fish in the sea and one has died. The fish will sink and land on the sea bed. The fish will then be buried in sand, rocks etc. The fish is compressed and heated by the earths core which causes (over time) the fish to change and form oil and gas.
We use an oil rig to drill down with a tube to suck up the oil.
