Suppose Earth Were to Cool Down a Little

question 117

Multiple Choice

Suppose Earth were to cool down a little. How would the carbon dioxide cycle tend to restore temperatures to normal?

• A) Cooler temperatures lead to slower formation of carbonate minerals in the ocean, so carbon dioxide released by volcanism builds up in the atmosphere and strengthens the greenhouse effect.
• B) Cooler temperatures cause volcanoes to become more active, so they release more carbon dioxide into the atmosphere than they do when temperatures are warmer.
• C) Cooler temperatures allow carbon dioxide to form rain and rain out of the atmosphere.
• D) Cooler temperatures mean more ice and more erosion, which somehow makes the planet warm up.
