View the video on the right and answer the questions below. 1) Carbon is found in the atmosphere as 2) Carbon is not found in 3) Movement of carbon across the many places it is found in is called the 4) The process that traps carbon, from the atmosphere, in the form of plant matter is called 5) What process does not release carbon back into the atmosphere 6) Fossil fuels are 7) Carbon dioxide can move between 8) Aquatic organisms make their hard shells from carbon they absorb from 9) Levels of carbon dioxide in the air have increased significantly over the last 100 years. This is largely due to 10) Explain how carbon dioxide contributes to climate change. |

Above is a simplified diagram of the amount of carbon stored in different carbon sinks and the amount that cycles between the carbon sinks in gigatons. The white writing represents carbon in carbon sinks while the yellow represents the flow of carbon between carbon sinks each year. The image above was obtained from http://genomics.energy.gov. |
