Answer:
B. The temperature increases by about 12°C and then decreases by about 12°C.
Explanation:
Antartica is a region known for its very low temperatures and its cold and inhospitable environment. However, this temperature in Antartica tends to vary with a certain frequency, in response to the environment around the world. As we know, planet Earth has gone through several moments of freezing, followed by moments of global warming. This happened around 440000 to 340000 years ago, when the land was still in its primitive state. During this period, Antartica presented a temperature change, increasing by around 12ºC and decreasing by 12ºC soon afterwards.
