Here is my weekly weather quiz question for the last time. What are “Crepuscular Rays?” Here is the correct answer. Crepuscular Rays are the alternating bands of light and dark (rays and shadows) seen at the earth’s surface when the sun shines through clouds. I’ll have a new weekly weather quiz question for you starting Monday. The first person to post the correct answer as a comment on this page will win a week of free personalized weather forecasts tailored to your needs. Good luck.
