Explain the role of the carbon cycle in regulating Earth’s temperature.

Which process removes carbon from the atmosphere?

Describe how human activities have altered the natural balance of the carbon cycle.

Using Figure 2 (The Carbon Cycle), identify two processes that increase atmospheric $CO_2$ and two processes that decrease it.

Why is the ocean considered both a carbon source and a carbon sink?

Explain how increased atmospheric $CO_2$ levels affect both the carbon cycle and climate systems.

Use Figures 1 and 2 and your understanding of the carbon cycle to answer: Is the carbon cycle important to global climate change?

Describe one strategy humans can implement to restore balance to the carbon cycle and mitigate climate change.
