Albedo refers to the fraction of sunlight an object or material reflects. The average albedo of Earth's surface is 30%, which is influenced by deforestation and farming activities.

Example of high friction is a really rough surface like sandpaper.

The answer to this question most likely has to do with the albedo of crayon (wax, charcoal, etc). Albedo is the extent to which an object diffusely reflects light from light sources, measured as a ratio. The lower the albedo, the more light/energy is absorbed into the object. Since darker colored objects absorb more energy, the albedo of a darker crayon is probably lower than the albedo of a lighter crayon. This means the darker crayon, while absorbing more energy, will heat up faster than the lighter crayon.This is why snow around a tree typically melts much faster and earlier than snow with nothing around it -- because of the tree bark's albedo is much lower than snow/ice and thus can absorb more energy faster, and heat up whatever is around it quicker.
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.
Actually the very highest Albedo is from fresh snow which reads .8 to .9 (1 being the highest possible on the Albedo scale)
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.
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.
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.
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.
Astronomers deduced that Pluto was probably covered with ice due to it's relatively high 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.

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).
no. a mirror has a high abedo (perhaps the highest)
