They reflect the sun's radiation.
reflect
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!
Melting ice caps increases the amount of light absorbed from the sun since the oceans absorb instead of reflect light, thus albedo, the ability to reflect light from the surface, is diminished.
Ice caps are areas of frozen water or gases that are created by the colder conditions near a planet's poles. In Earth's case, its tilt compared to its orbit gives us seasons, but the shallow angle of sunlight (plus the higher albedo or reflectivity of snow) means that there are large, permanently frozen ice caps in Greenland and in Antarctica.
No , they ,particularly deserts are major biome
Ice caps are called polar deserts because they receive very little precipitation in the form of rain or snow, much like traditional deserts. Despite the presence of ice, the extremely low temperatures in these regions prevent significant snowfall, leading to a lack of liquid water and barren landscapes.
Albedo is a positive feedback. If there is less ice, there earth will not be able to reflect as much radiation and it will warm a little bit more. This will cause continued enhancement of ice melt.
Such reflection is called the albedo. For the earth it is 30 - 35%
grow page 17 huh, deserts
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.
A low albedo means that a surface absorbs more sunlight and heat, leading to warming. This can contribute to climate change by increasing temperatures and melting ice caps, which in turn can lead to rising sea levels and changes in ecosystems.
Earthworms are found all around the world , but usally do not live in deserts or ice caps
