1. 5 pts. Use charts A, B, and C to answer the following questions L What are the slopes (with their units) of the trendlines for the 3 charts? In words, what does each slope mean? 2' Which of the charts shows the highest correlation? What can you say about that relationship? 3. which of the charts shows the lowest correlation? 4' Do you think that because the C01 concentration and the temperature are correlated means that the increase in CO; concentration necessarily causes the rise in temperatures? 5, The correlation can be a starting point for scientic research. What are somethings that scientists might study after considering the relationship between the increasing CO: concentration and the Increase in temperature? C. CO2 vs. Year A.
