Light is reflected from surfaces based on their texture and color. The amount of light reflected is called the reflectivity of the surface. Reflectivity is important in determining our climate on Earth. Things like oceans, trees, ice, and deserts greatly affect how much of the sun’s light energy is reflected and how much heats the Earth.
