DUST Beauty

Without dust, there would be less rainful and sunset would be less beautiful. Rain is formed when water molecules in the air collect around particles of dust. When the collected water becomes heavy enough, the water droplets fall to the earth as rain. Thus water vapor could be much less likely to turn to rain without dust particles. The water vapor and dust particles also serve to reflect the rays of the sun. At sunrise and sunset, when the sun is below the horizon, the dust and water vapor molecules reflect the longer red wavelengths of light such that we can see them more for more time- starting earlier(in the case of sunrise) and lasting longer(in the case of sunset)than any other wavelength. The more dust particles in the air, the more colorful the sunrise or sunset.

Be aware, in Calama, a town in the Atacama Desert in Chile, it has never rained.
