What is the cryosphere?

Cryosphere is a scientific name for all frozen water on the Earth's surface: ice caps, glaciers, sea ice, ground ice, frozen lakes, snow, permafrost, etc. The rats are an important part of the planet as a whole, providing cooling effect by reflecting the sun back into space and causing positive refrigeration cycles. Today, the cryosphere is much greater than in the course of most of the history of life, when the forests spread from the pole to the pole and the crawl have been limited to the mountains in extreme latitudes. Since Antarctica was separated from the continent of Australia 20 million years ago, he had cooled the continent and caused him to cover the ice throughout the year. The largest volume of ice in the cryosphere is concentrated in East Antarctic Ice Layer, which can be up to about two miles to depth. 90% of the volume of global ice leaves are found in Antarctica, with another 9.5% in Greenland and only 0.5% found in other areas such as North Canada, Russia, Scandinavia and Alaska. Rust timeDence of the ice particles in the ice cover can be very long, between 100,000 and 1 million years. Overall, world ice leaves contain 77% of the global total number of fresh water.

As far as the area is concerned, the snowy soil forms the second largest component of the cryosphere on ice leaves. The extent of snowy soil is a very seasonal-flying snow cover is only about 10% of winter snow cover. The vast majority of snow -covered soil is located in the northern hemisphere because the southern hemisphere is missing to cover snow. Human trunks and different animal species are able to colonize snowy soil, but usually not direct ice plates that do not have the soil for plant growth. A few exceptions are polar bears and penguins that live near the shores and consume fish.

Since climate change continues to increase the average global temperature, the range of cryosphere slowly decreases. It is estimated to add the melting cryosphere by 2100At least a few inches on the world's sea level.
