What Fossil Fuels Represent?
Fossil fuels represent carbon storage areas. Carbon that is locked in these fossil fuels does not cycle through the Earth. When humans burn fossil fuels, the stored carbon is released into the atmosphere as carbon dioxide.
The Carbon Cycle
All living things are made of carbon. Carbon is also a part of the ocean, air, and even rocks. Because the Earth is a dynamic place, carbon does not stay still. It is on the move!
In the atmosphere, carbon is attached to some oxygen in a gas called carbon dioxide.
