Carbon Cycle and Fossil Fuels

The video tutorial covers part B of the carbon cycle gizmo, focusing on human activities and their impact on the carbon cycle. It explains the formation of fossil fuels like coal and petroleum, and how natural gas is formed. The uses of fossil fuels and their contribution to atmospheric carbon dioxide are discussed. The video also explores the cement industry's role in the carbon cycle. Students are encouraged to find additional pathways and uses for extra credit.

What is the primary effect of burning fossil fuels on the atmosphere?

• Decreases oxygen levels
