what causes different colors to appear in the sky? the absorption of light by air molecules the reflection…

Brief Explanations:

The different colors in the sky are mainly due to the scattering and reflection of light by dust particles and air - molecules. Air - molecules scatter shorter - wavelength light (like blue) more, which makes the sky blue during the day. At sunrise and sunset, light has to travel through more of the atmosphere, and longer - wavelength light (like red and orange) is more visible as shorter - wavelength light is scattered away. Dust particles also contribute to the scattering and reflection of light, affecting the color appearance. Absorption of light by air molecules is not the main cause for the visible colors in the sky. Reflection of light by bodies of water is not relevant to the color of the sky itself. The greenhouse effect in Earth's atmosphere is related to heat trapping and not to the color of the sky.

Answer:

the scattering and reflection of light by dust particles
