Maybe Sean mixed up the questions on the test. Anyway, here's my #29, along with my answer.
29 (5 points)
Describe the effect of increased cloud cover on the growth of coccolithophorids and explain the sequence of events that occurs with regards to coccolithophorid growth and cloud formation following increased cloud cover.
The more clouds there are, the more sunlight is reflected away from the planet, causing fewer of the sun's rays hit the ocean. This directly affects the amount of CCN that is created. Clouds are formed when water vapor in the atmosphere freezes or condenses around the CCN's. The more clouds there are, the less CCN is created; the fewer clouds we have, the more of the sun's rays hit the water, which causes a greater amount of CCN to be released, which in turn causes more clouds, etc. And the cycle goes on.
Score: 2.5 / 5
Did you get a "5" on this question? If so, what is the answer??
Thanks for helping!
