C)Rayleigh scattering.
D)atmospheric absorption.

Question

Quizplus · Accepted Answer

The blue color of the sky in the middle of the day is due to Rayleigh scattering, which occurs when the sun's radiation interacts with gas molecules in the Earth's atmosphere. This scattering process causes shorter wavelength colors (like blue) to be scattered more, making the sky appear blue to the human eye. Nonselective scattering, atmospheric transmittance, and atmospheric absorption can affect how much light reaches the Earth's surface, but they do not directly cause the blue color of the sky.
