Crude oil is a naturally occurring fossil fuel - meaning it comes from the remains of dead organisms.
Crude oil is made up of a mixture of hydrocarbons - hydrogen and carbon atoms.
It exists in liquid form in underground reservoirs in the tiny spaces within sedimentary rocks. Or it can be found near the surface in oil sands.
It is often found alongside natural gas and saline water.
Crude oil is often interchangeably referred to as petroleum. This is because petroleum includes both the unrefined crude oil as well as refined petroleum products.
It is non-renewable - once it’s gone it’s gone and cannot be easily replaced.
The movement of water on and above the earth's surface is called the hydrologic cycle, or the water cycle. Hope this helps!
