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.
How do clouds affect earth's energy budget?
Clouds can have a cooling albedo effect, reflecting incoming energy. They can also have a warming effect, when they prevent energy escaping into space.
Which planetary property does not play a role in determining a planet's atmospheric temperature a distance from the Sun b its albedo c the greenhouse effect d None of the?
All of the above play a role in determining atmospheric temperature: the planet's distance from the sun, its size, albedo, and greenhouse effect.The answer to this homework question is: ALL OF THE ABOVE:)
How does altitude affect the composition of clouds?
The greenhouse effect is weak for low altitude clouds, so their albedo effect dominates and they cool the Earth's climate. In contrast, cold high altitude cirrus clouds may either cool or warm the climate.
What is Reflectivity of the Earth's surface called?
Albedo
Same and differences of albedo and insolation?
The albedo effect is how a darker material gets hotter faster than a lighter material. Insolation is the solar radiation from the sun.
How does the albedo effect keep the polar regions cold?
it reflects the radiation because the snow is white
Mars has an albedo magnitude of?
The albedo of Mars is .15; you can see the albedo of all of the planets and moons in the solar system at the Nine Planets web site, linked below. "Albedo" is a measure of how reflective a body is. The higher the number, the more reflective the surface. So a high albedo says that a planet or asteroid reflects most of the light that hits it, while a low albedo indicates that most of the light is absorbed. Albedo can make calculations about climate change difficult. A planet with a high albedo reflects much of the Sun's light and heat, causing it not to heat up as much. A low albedo means that all of the solar radiation is absorbed and turned into heat. A warmer world will have less snow and ice cover, and thus a lower albedo, resulting in higher temperatures. On the other hand, a warmer world might have more clouds, which would increase Earth's albedo, reflect more sunlight, and reduce the heating effect. However, clouds also act to trap heat, sort of like a blanket. Whether the albedo effect would offset the "blanket" effect of clouds would depend on the type and height of the clouds and where they are located. Cloud effects are among the most important sources of uncertainty in modeling future climate change.
The fraction of incident light that a body reflects is known as its?
" albedo "
Which cause more light reflection albedo 2 or albedo 3?
Albedo is a measure of reflectivity; it is a measure of the percentage of light reflected from a surface. A perfect mirror would have an albedo of 1, while white snow has an albedo of about 0.9. Charcoal has an albedo of about 0.04.An albedo higher than 1 is impossible.
The surface reflectivity of a planet or moon is called?
Albedo. The albedo of the Earth is 0.367. When Vangelis released his album, Albedo 0.39, that was what the albedo of Earth was in 1976.
What is the importance of albedo?
The albedo effect reflects the sun's radiation helping to slow the effects of global warming (like sea ice, white ice caps and glaciers). If (or when) these melt, then the reflection will stop and the warming will speed up!
What is the albedo of Neptune?
The average overall albedo of Earth, itsplanetary albedo, is 30 to 35%, because of the covering by clouds, but varies widely locally across the surface, depending on the geological and environmental features.
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.
How do clouds affect earth's energy budget?
Clouds can have a cooling albedo effect, reflecting incoming energy. They can also have a warming effect, when they prevent energy escaping into space.
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.
When did Albedo Anthropomorphics happen?
Albedo Anthropomorphics happened in 1983.
