Study Notes
Carbon and the Carbon Cycle
- Carbon is an element and the basis of life on Earth.
- Carbon is found in rocks, oceans, and the atmosphere.
Human Impact on the Carbon Cycle
- Fossil fuels release stored carbon very slowly.
- Burning fossil fuels and other organic materials releases additional carbon into the atmosphere.
- This increased carbon dioxide in the atmosphere contributes to global warming.
- With fewer plants, less CO2 is removed from the atmosphere.
Understand the basics of the carbon cycle, its importance in life on Earth, and how human activities like burning fossil fuels affect the environment and contribute to global warming.
