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.
Which has a greater heat capacity--water or land?
One way that land and water differ when it comes to absorbing and losing heat is that water can do so by way of phase change - freezing, melting, evaporating, or condensing. Land tends to stay solid. Water also tends to be much more reflective than land - not always, but in general it is. Land tends to be both a better absorber and radiator of heat.
Does water or land reach a higher temperature?
Water (oceans) is slower than land to warm up, and also slower to cool down.
Why is the sufrace of land is usually warmer than the surface of a nearby body of water because the water?
has a higher density
Why does water stay cooler than land?
The thermal capacity is higher for water than land, therefore the land is able to cool faster than the water. The water takes a longer time to heat up and cool off than the land.
A higher albedo means there will be what?
A higher albedo means that a higher percentage of incoming light is reflected.
What does A higher albedo mean?
A higher albedo means that more of the incident radiation is reflected, and less of it is absorbed.
Does a lake make a difference to micro climate?
Yes lakes can make a difference to micro climate. This is because the albedo value for water is much higher then that of the surrounding land, meaning it will absorb much more solar radiation. This will make the water warmer then the land, and create a micro climate.
Does farmland have higher albedo than ice?
Few things have higher albedo than ice - farmland is lower, but still higher than the forest which it probably replaced.
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.
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.
Which has a higher albedo sea ice or soil?
naturally sea ice would have the advantage of having a greater albedo
Would A higher albedo result in an overall cooler climate?
A higher albedo would mean that more energy would be returned to space. This would mean a cooler climate.

Why does the South Pole have a higher albedo than the North Pole?
There is more ice on Antarctica to reflect the sun's rays back into space -- albedo, than there is in the Arctic Ocean.
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.
Does the land area or water area of Earth's surface absorb more solar energy?
Short Answer:Since there is so much more water than land, one expects that most of the solar energy absorbed by Earth is absorbed into the oceans. That is correct.Crudely, twice as much energy is absorbed by the oceans as the land since there is roughly a bit more than twice as much ocean as land.More Technical (Albedo):The characterization of how much solar energy is absorbed by a portion of the surface of the Earth is something called the albedo of the surface. Some surfaces, like dirt, forests and the ocean absorb most of the Sun's energy. Others, like Snow reflect most of it. Deserts are in between.The albedo of a surface is the fraction of light it reflects. (The term "reflects" does not mean like a mirror but rather means scatters or causes to light bounce back to distinguish "reflection" from the process where light is absorbed.) Normally, one refers to sunlight when quoting an albedo, but if a different or specific wavelength range is being considered, there are different values of the albedo that are defined for different parts of the electromagnetic spectrum.On average, the ocean surface has a low albedo meaning it absorbs most of the light that gets to it.The same is true for bare soil and most forests.Though the albedo is variable, 70 or 80 % of the light is absorbed.Desert areas typically have high albedos and can reflect most of the light.Most land areas are in an albedo range of 0.1 to 0.4, so 90% to 60% of the light is absorbed.The average albedo of the Earth is about 0.3, somewhat higher than typical of oceans or much of the land area primarily because of the contribution of clouds.Clouds reflect light very effectively, absorbing little.
