Carbon Dioxide and the Carbon Cycle

Interactive visualization that provides a basic overview of the Earth's carbon reservoirs and amount of carbon stored in each, CO2 transport among atmosphere, hydrosphere, geosphere, and biosphere, and a graph comparing global temp (deg C) and atmospheric CO2 levels (ppm) over the past 1000 years.

Teaching Tips

Educator should have more background information regarding questions that these images will likely bring about. It would also be good to consider using this resource as a way for students to be introduced to the carbon cycle before launching into a larger lesson on the carbon cycle.

Educators will want to consider the residence time for carbon in these different sources and sinks and how the movement of carbon more quickly or more slowly from one place to another affects the cycle.
