Answer the 5 questions below:
1. (5 points) There are many examples/proof that global Climate Change is happening. Choose two of the 4 processes listed below and explain the evidence available as to how this process is relevant to global climate change. The evidence can be an explanation of how it is correlated to global Climate Change or you can statistics number, charts or scientific studies count as evidence depending on A-D below.
A. Sea level rise
B. Increase in atmospheric CO2
C. Ocean acidification
D. Increase in atmospheric temperature
2. (5 points) Geologic research has shown that, historically, atmospheric CO2 concentrations have increased when oceanic ridges are spreading quickly, and atmospheric CO2 concentrations have decreased when oceanic ridges are spreading slowly.  Today, oceanic ridges are moving slowly.  So why is CO2 higher today than historical records?
3. (5 points)
A. What would happen to the global temperature if spreading rates decreased? You must explain WHY for full credit and mention spreading rates decrease in your answer. Hint: Refer to question 2 and link CO2 to global temperature.
B. What would happen to the global temperature if spreading rates increased? You must explain WHY for full credit and mention spreading rates increase in your answer. Hint: Refer to question 2 and link CO2 to global temperature.
4. (5 points) Explain two ways you benefit from primary production in the ocean. Then, explain one way that you are negatively affected by primary production in the ocean.
5. (5 points) How does the Biological Carbon Pump differ from the Physical Carbon Pump? (Both must be explained well for full credit).
