Question

1. which factor causes wind chill to make temperatures feel colder?

a. rising temperatures
b. lower humidity
c. increased wind speed
d. low sunlight

Explanation:

Wind chill is the sensation of coldness due to the combined effect of air temperature and wind speed. As wind speed increases, it removes the warm layer of air around the body more quickly, making it feel colder. Rising temperatures (a) would make it feel warmer, lower humidity (b) relates more to heat index in warm conditions, and low sunlight (d) doesn't directly cause wind chill's cooling effect. So increased wind speed (c) is the factor.

Answer:

c. Increased wind speed
