Albedo is a measurement term used by astronomers of the amount of sunlight reflected by a planetary surface. Albedos arrange 1 for complete reflection to 0 for complete absorption. The Albedo of Earth’s is 0.33, while ice and clouds can lie near 1.0, the ocean is measured less than 0,2. Vegetation usually has a lower albedo than the average planetary. This happens because leaves evaporating water. Snow and ice melt and disappear as a result of global heating and lead to greater absorption of sunlight, which creates even more general heat.
