Many clouds have albedo?
Yes, everything has albedo. Albedo refers to the reflectivity of any object or substance. White clouds have a high albedo - they reflect a lot of light. Dark clouds have a lower albedo; they don't reflect as much.
What is meant by 'albedo' of a planet?
Albedo is the fraction of sunlight that hits a planet that is reflected back out into space. A bright white planet that's full of ice would have a high albedo.
What is the percentage of solar radiation reflected from a surface?
This is called the "albedo." It is the ratio of reflected light compared to incident light, and depends on the surface material and its condition (e.g. snow, grassland).
As the amount of sunlight you see reflected increases what does it increase?
This is a question where the meaning isn't totally clear. Perhaps it's a reference to "albedo". Albedo is a measure of the fraction of light reflected by planets, etc. The more sunlight that is reflected, the higher is the object's albedo. For example, the brilliant planet Venus has a very high albedo.
What objects reflect almost all of the light?
Mirrors do an excellent job. White painted surfaces also have a higher albedo. Ice, frost, and snow reflect a lot of light.
Why are light surfaces colder than dark surfaces?
Light surfaces are colder than dark surfaces due to an object's albedo. Albedo is the amount of incoming radiation (energy) that an object either absorbs or reflects. Light surfaces have a high albedo, thus reflecting more of the incoming radiation. Dark surfaces have a low albedo and will absorb more radiation. Because it is absorbing more radiation, the object heats up due to an increase in sensible heat (i.e. more energy). This theory explains the urban heat island effect, identifying why urban (city) areas are typically warmer than surrounding areas. The black pavement and rooftops in a city give the city a lower albedo than surrounding vegetated areas and thereby increase the temperature of urban areas by 2-3 degrees Celsius.
Does moisture greatly affect the albedo of surfaces or objects?
Ofcourse it does u idiot

Where is there high albedo?
Actually the very highest Albedo is from fresh snow which reads .8 to .9 (1 being the highest possible on the Albedo scale)
What has the lowest albedo?
Albedo means reflectivity. The higher the albedo, the more light (and heat) is being reflected. Generally, the darker the color, the lower the albedo : most of the energy is absorbed. Snow has a fairly high albedo, as do clouds. Black tar roofs have a very low albedo.
What is something that has low albedo?
An object that has a high albedo is one that is highly reflective, but a poor absorber. An object that has a low albedo is one that does not reflect well, therefore, is a good absorber. This means that a black object has low albedo.
What has the author Shaharuddin Ahmad written?
Shaharuddin Ahmad has written: 'The albedo of agricultural and urban surfaces in the Leeds area'

How do you use albedo in a sentence?
Astronomers deduced that Pluto was probably covered with ice due to it's relatively high albedo.
Does earth's surface absorb thermal energy at the same rate?
No! Different surfaces absorb and reflect differing amounts of radiation from the sun. The degree of reflectance is known as "albedo". Some materials reflect much more energy than others. For example snow fields reflect a very large proportion of solar radiation (they have a high albedo) whereas materials like tarmac (which is black and so reflects very little radiation, and conversely absorbs the majority of it) has a low albedo. This is why tarmac (and other dark surfaces) can become very hot on a sunny day.
Which Earth material has the highest albedo?
Probably snow, if your Earth includes the totality of items found on the planet. Some clouds would have an albedo almost as high - but only in parts. If you wish to limit your answer to earth solids, then perhaps milky quartz, and marble would have a high albedo.
What are 3 examples of a high albedo?
snow, white paper
