Scattering:
A) is responsible for the redness of sunsets.
B) prevents nearly half of incoming solar radiation from reaching the surface of the earth.
C) is the primary mechanism of heat transfer in the atmosphere.
D) changes the wavelength of light.

Question

Quizplus · Accepted Answer

Scattering is responsible for the redness of sunsets because the atmosphere scatters shorter, blue wavelengths of light more strongly than longer, red wavelengths, causing the red hues to become more visible during sunset. However, option B is also partly correct as scattering does play a role in reducing the amount of solar radiation that reaches the surface of the earth. Option C is incorrect as convection is the primary mechanism of heat transfer in the atmosphere. Option D is partially correct as scattering does change the path and direction of light, but it does not change the actual wavelength.
