Carbon Cycle Assessment

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.
