WebUnderstanding Albedo. Understanding Albedo. This activity teaches students about the albedo of surfaces and how it relates to the ice-albedo feedback effect. During an experiment, students observe the albedo of two different colored surfaces by measuring the temperature change of a white and black surface under a lamp. Click to View. WebAlbedo is the portion of solar energy reflected from the surface of the Earth back into space. It is a reflection coefficient and has a value of less than one. When the solar radiation passes through the atmosphere, a certain amount of it is scattered, reflected and absorbed. The reflected sum of radiation is called the albedo of the earth. WebReview albedo with students and explain that the blacktop feels hotter because it has a lower albedo and absorbs more of the energy from the Sun. This is the same reason a black shirt feels hotter on a hot day than a white shirt. The white shirt has a high albedo. harwich catholic church

WebNov 10, 2024 · Albedo is part of the energy from the sunlight that casts back into the atmosphere. These rays have a significant effect on our climate. When the albedo rises, the universe reflects light more and consequently, higher levels of radiation are sent back to space so the Earth cools down. Albedo determines the level of heat on the Earth.
