What is meant by 'albedo' of a planet?
Albedo refers to the measure of how well a surface reflects sunlight. It is a unitless quantity, usually expressed as a percentage. A high albedo means a surface reflects a lot of sunlight, while a low albedo means it absorbs more sunlight.
What is a planet's reflectivity called?
A planet's reflectivity is called its albedo, which is a measure of how much sunlight is reflected by the planet's surface. A high albedo means more light is reflected, while a low albedo means more light is absorbed. Albedo can affect a planet's climate by influencing its temperature.
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 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).
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.
Would snow have a low or high albedo value?
Snow would have a high albedo value. Albedo is a measure of how well a surface reflects solar energy. Snow reflects a high percentage of sunlight, which is why it appears bright, giving it a high albedo value.
Does a high albedo increase temperature?
No, a high albedo does not increase temperature. Albedo refers to the amount of sunlight reflected by a surface, so a high albedo means more sunlight is reflected and less is absorbed, which can help to keep temperatures lower.
Does snow have a high or low albedo?
Snow has a high albedo, meaning it reflects a lot of sunlight back into the atmosphere.
Does ice possess a high albedo?
Yes, ice possesses a high albedo, meaning it reflects a high percentage of sunlight that hits its surface.
What does a high albedo indicate about a surface's ability to reflect sunlight?
A high albedo indicates that a surface has a strong ability to reflect sunlight.
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 the differences in the amount of solar radiation absorbed by surfaces with high versus low albedo?
Surfaces with high albedo reflect more solar radiation, while surfaces with low albedo absorb more solar radiation.
What are the differences in the amount of solar radiation absorbed and reflected between surfaces with low albedo and surfaces with high albedo?
Surfaces with low albedo absorb more solar radiation and reflect less, while surfaces with high albedo reflect more solar radiation and absorb less.
Does a mirror have a low albedo?
No, a mirror does not have a low albedo. Albedo refers to the reflectivity of a surface, with values ranging from 0 (absorbs all light) to 1 (reflects all light). Mirrors typically have a high albedo as they reflect a significant amount of light.
What is meant by 'albedo' of a planet?
Albedo refers to the measure of how well a surface reflects sunlight. It is a unitless quantity, usually expressed as a percentage. A high albedo means a surface reflects a lot of sunlight, while a low albedo means it absorbs more sunlight.
How do you use albedo in a sentence?
Astronomers deduced that Pluto was probably covered with ice due to it's relatively high albedo.
What is a planet's reflectivity called?
A planet's reflectivity is called its albedo, which is a measure of how much sunlight is reflected by the planet's surface. A high albedo means more light is reflected, while a low albedo means more light is absorbed. Albedo can affect a planet's climate by influencing its temperature.
