Why are the sun’s UV rays more harmful in the afternoon than in the morning or evening?

412 viewsOtherPlanetary Science

I always hear that we should avoid the sun or make sure to put on sunscreen in the afternoon when the sun is the most intense. Why is the sun’s rays more harmful when it is directly overhead vs in the morning soon after sunrise? Either way, the sun is shining directly on me so not sure what causes the difference in intensity.

Take a piece of bread, put a dot in the center. Try to touch from either side (morning/evening) then try to touch it from the top. 

The amount of bread you push through is the same as the air the light has to “push” through.
