1 : reflective power specifically : the fraction of incident radiation (such as light) that is reflected by a surface or body (such as the moon or a cloud) — compare reflectance.View full answer
Similarly one may ask, What does the word albedo mean?
Albedo, fraction of light that is reflected by a body or surface. It is commonly used in astronomy to describe the reflective properties of planets, satellites, and asteroids. It is an important consideration in climatology since recent albedo decreases in the Arctic have increased heat absorption at the surface.
Then, What is an example of albedo?. Albedo is the measure of the reflectivity of a material. ... An example of a high albedo material is snow and ice. One of the reasons why snow and ice can hang around for a long time after they have fallen in winter is that they are white (and so absorb no or little sunlight) and have a reflective quality as well.
Also asked, What is the albedo of the earth?
The average albedo of Earth is about 0.3.
What has the highest albedo on Earth?
Snow and ice have the highest albedos of any parts of Earth's surface: Some parts of Antarctica reflect up to 90% of incoming solar radiation.
A value of 1 means the surface is a "perfect reflector" that reflects all incoming energy. Albedo generally applies to visible light, although it may involve some of the infrared region of the electromagnetic spectrum.
When sunlight hits pale colored surfaces, much of it is reflected, bouncing back out to space. When sunlight hits dark colored surfaces, very little of it is reflected. Most of it is absorbed. The amount of energy reflected by a surface is called albedo.
Here on Earth, the albedo effect has a significant impact on our climate. The lower the albedo, the more radiation from the Sun that gets absorbed by the planet, and temperatures will rise. If the albedo is higher, and the Earth is more reflective, more of the radiation is returned to space, and the planet cools.
Remember that albedo is calculated by dividing the reflected radiation by the incoming radiation: Albedo = reflected light/incoming light; You can calculate the albedo of any surface.
Notice how the highest albedo values are in regions where Earth is mostly covered by snow and ice, or clouds, or both. The lowest albedo values occur in forest-covered landscapes or open ocean.
Albedo is the reflectivity of a surface. A surface that has a high albedo reflects a lot of solar radiation from the sun back into the atmosphere, whilst a surface that has a low albedo reflects little solar radiation, absorbing it instead.
Is Albedo a good character in Genshin Impact? From what we know so far, Albedo is a fairly middle of the road five-star character. He's a support character that uses the Geo element and a single-handed sword. ... Despite a cool design and great voice actors, there's nothing outstanding about Albedo just yet.
Snow, ice, and clouds have high albedos (typically from 0.7 to 0.9) and reflect more energy than they absorb. Earth's average albedo is about 0.3. In other words, about 30 percent of incoming solar radiation is reflected back into space and 70 percent is absorbed.

Albedo sentence example
Water formation as cloud droplets: Clouds are efficient cleansers of atmospheric pollution and clouds contribute to an increased global albedo . albedo features with very low relief. albedo change on drought in semi- arid regions.
The higher the albedo, the more the surface reflects light. Snow and ice have high albedos; a dark rock would have a lower albedo. ... Snow and ice have high albedos; a dark rock would have a lower albedo. The higher the albedo, the more the surface reflects light.
Light surfaces reflect more heat than dark surfaces. This is called the albedo effect. When the Earth's temperature dropped because of its position in orbit around the Sun, and the tilt of the axis, the ice sheets grew. This in turn caused more heat to be reflected and the ice sheets to expand further.
Albedo is the fraction of solar energy that is reflected back from Earth to space. ... Deserts, ice and clouds, however, have high albedos; they reflect a large portion of the sun's energy. The high albedo of ice helps to insulate the polar oceans from solar radiation.
The color a person perceives indicates the wavelength of light being reflected. White light contains all the wavelengths of the visible spectrum, so when the color white is being reflected, that means all wavelengths are being reflected and none of them absorbed, making white the most reflective color.
