Answer to Question 1

Rayleigh is the differential scatter of visible light due to the presence of atmospheric gases and particulates smaller than the wavelengths of most visible light. As a result, mostly light in the blue and violets wavelengths are scattered, given the sky on a clear day it's blue color.

Answer to Question 2

Albedo is the reflective quality of a surface. Lighter objects have higher albedo; darker objects have lower albedo.For instance, white sand dunes have a higher albedo than a rainforest canopy.
