Describe the event(s) that limited the amount of sunlight to reach Earth's surface during the K-Pg
extinction?

he movement of air through earth's or any planet's atmosphere is called wind, and the main cause of earth's winds is uneven heating by the sun. this uneven heating causes changes of atmospheric pressure, and winds blow from regions with high pressure to those with low pressure.

i hope this : )

and after water is usually warmed by the sun the water temperature raises and then evaporates .
