AQA A-Level Geography carbon cycle unit of work revision notes. I updated these revision notes throughout my two years studying for Geography. I achieved an A grade in Geography (August 2019).
These notes are comprehensive, easy to read revision notes ( 9 pages) - I recommend using these notes and putting them into your own words for optimum use!
- Global distribution, and size of major stores of carbon – lithosphere, hydrosphere, cryosphere
- Factors driving change in the magnitude of these stores over time and space, including flows and transfers at plant, sere and continental scales. Photosynthesis, respiration, decomposition, combustion, carbon sequestration in oceans and sediments, weathering.
- Changes in the carbon cycle over time, to include natural variation (including wild fires, volcanic activity) and human impact (including hydrocarbon fuel extraction and burning, farming practices, deforestation, land use changes).
- The carbon budget and the impact of the carbon cycle upon land, ocean and atmosphere, including global climate.
