Instructions: Identify the word or group of words being referred to in the following statements.
_________________ 1. It occurs when particles absorb light and scatter it in all directions.
_________________ 2. This color is being scattered the most by the particles in the atmosphere.
_________________ 3. It is the scattering of light that depends on the relative size of the particles
and the wavelength of light.
