Carbon dioxide in the atmosphere
I can explain how changing factors in the carbon cycle affects the amount of carbon dioxide in the atmosphere over time.
Lesson details
Key learning points
- Burning fossil fuels adds more carbon dioxide to the atmosphere.
- Carbon dioxide produced from a combustion reaction may eventually spread throughout Earth’s atmosphere.
- Increased ocean temperatures reduce the quantity of carbon dioxide that is dissolved in them.
- The difference between the rates of addition and removal of carbon dioxide changes its overall levels in the atmosphere.
Common misconception
Plants can absorb all excess carbon dioxide.
There are limits of carbon dioxide absorption by plants.
Keywords
