What are surfaces with high albedo and low albedo?

Albedo is the measurement of a surfaces ability to diffuse and reflect oncoming radiation, scores range from 0 ( an ideal blackbody that absorbs any and all incident radiation) to 1 ( an ideal white body that completely diffuses and reflects all incident radiation). A simple way to think about this concept is in the terms of sunlight, a black or darkly colored surface will always absorb much more of the heat (radiation) than a white or lighter colored one, for the lighter objects reflect the sun's energy much easier.

This effect is nothing other than the reflection of solar radiation when it affects the planet. Light surfaces have more albedo reflecting most of the radiation and dark surfaces less albedo since they absorb radiation.

Explanation:

The albedo of all these combined surfaces is called the planetary albedo. The planetary albedo of the earth is approximately 0.31. That means that about one third of the solar energy that reaches the earth is reflected back into space and only about two thirds is absorbed. The albedo of the moon is 0.07, which means that only 7% of the energy that reaches it is reflected. The albedo of distant planets, so distant that they are difficult to study with telescopes, could be very helpful for scientists trying to determine what a planet is made of.

This effect is much greater the clearer the surface; for example, on snow or ice surfaces, up to 90% of the incident radiation can be reflected and therefore the UV rays would bounce continuously between the snow and the atmosphere. This effect is therefore a source for example of the thaw after glacial times, where with so much white surface the world temperature overheats and the glacier season ends.

The albedo effect is very significant for the human being, and more now when many of the defenders of the theory of global warming, come to their reasoning to explain how if the poles melt and there are less and less glaciers the earth by natural order is It will start to reheat faster.

a = p(1 + rt) . . account balance after time t at rate r starting with principal p

3000 = 2500(1 + 0.0202t) . . filling in the given numbers

1.2 = 1 + 0.0202t . . divide by 2500

0.2 = 0.0202t . . . subtract 1

0.2/0.0202 = t ≈ 9.901

it will take about 9.9 years for the account balance to reach $3000.
