What is oil

Oil is formed from the dead animals that died along time ago

Oil is nonrenewable. It cannot be reproduced.

This is used for fuel,but it causes harm to the environment and air. This is found all over the world. We drill this resource out of the Earth by working in oil fields. Oil is expensive all over the world.

This is a useful but harmful.
