Q

How is Oil/Natural Gas formed?

A

Millions of years ago, small plants and animals fell to the bottom of the sea. Layers of mud and sediment were washed over them, putting them under lots of pressure on the decaying organic matter. This pressure, along
with the heat from surrounding rocks, changed the material into crude oil and gas.
