One-day weather temperature change curve

Question 1:C

Question 2:C

Question 1: According to Figure 1, the temperature difference between day and night indicated by curve A is small, while that indicated by curve B is large; Curve A represents cloudy days and cloudy nights, and curve B represents sunny days and sunny nights. The small temperature difference between day and night indicated by curve A is due to the weakening effect of clouds on solar radiation during the day, and the heat preservation effect of the ground atmosphere at night is mainly affected by ① and ③.

Question 2: Through low-carbon economy and low-carbon life, human beings reduce the content of carbon dioxide in the atmosphere and weaken the anti-radiation effect of the atmosphere.
