Carbon Cycle Assessment Notes
- Photosynthesis is indicated by the process represented by the purple arrow, converting carbon dioxide into organic matter using sunlight.
- Volcanic eruptions release carbon dioxide dissolved in magma into the atmosphere, illustrating the transition from the geosphere to the atmosphere.
- An example of a transition from the biosphere to the geosphere is depicted in Image D, representing carbon movement from living organisms to earth materials.
- Multiple processes contribute to the addition of methane (CH4) in the atmosphere, and all listed processes are effective in increasing atmospheric methane levels.
- If the atmospheric carbon reservoir's inputs and outputs are maintained as described, the total carbon in the atmosphere is projected to reach 780 gigatons of carbon (GtC) over ten years.
