When the sun's rays enter Earth's atmosphere, they are ______ than they are when they are leaving Earth's atmosphere.

A. traveling faster
B. traveling at the same speed
C. less energetic
D. longer wavelengths



Answer :

Final answer:

Sun's rays are more energetic when entering Earth's atmosphere compared to when leaving. Difference in radiation wavelengths creates the greenhouse effect.


Explanation:

When the sun's rays enter Earth's atmosphere, they are more energetic than they are when they are leaving Earth's atmosphere.

The sun emits shortwave radiation mainly in the ultraviolet and visible wavelengths, while Earth emits infrared radiation with longer wavelengths due to its cooler temperature.

This difference in wavelengths of incoming solar radiation and outgoing radiation creates the greenhouse effect, affecting energy absorption in the atmosphere.
