card C: Location of South China, during the time of the Late Carboniferous, South China was about 10°S (South) but today, it is about 20°N (North). This means that today, South China is a little further from the equator than during the Late Carboniferous. Since South China is further from the equator today, the prevailing winds push the ocean currents further from the equator, which makes it colder because the ocean currents are carrying less energy. During the Late Carboniferous, since South China was closer to the equator at that time, the ocean currents had more energy than they do today, which caused the air temperature to be warmer. As we have learned in lesson 1, latitude can tell us much about the air temperature already. The further from the equator you are, the colder it will be. But in Lessons 2 and 3, we learned that a change in prevailing winds could change the direction of ocean currents. The more energy an ocean has, the closer to the equator it is, but also the warmer it will make the air temperature.
