What is an ice scale?

Ice layer is a large permanent layer of ice covering the continental shelf, defined as a range of more than 50,000 km ^{2 (19 305 miles ). The ice layer is larger than the iceberg or ice shelf. Today there are two ice leaves in the world: Antarctic ice scale (which contains 61% fresh water on the planet) and Greenland ice leaf (containing 7%). Only about 32% of the world's fresh water is found in streams, lakes and a aquifer layer - the rest can be found in ice leaves. Over thousands of years, snow has been built and compacts into ice, creating an average of 1 miles (1.6 km), or up to 2 miles (3.2 km) to the maximum. In some areas of the western Antarctic ice cover, the base is up to 1.5 miles (2.4 km) below the sea level, comparable to the depth of some areas of the ocean. If the whole Antarctic ice cover or the ice surface of Greenland could, the World Sea would increase by about 60 meters or 7 meters. The possibility of melting ice leaves as a result of global warming was in the lastdecades of cause of concern around the world.}

Earth covered with ice leaves occupies a characteristic jagged appearance due to extensive glacial weathering. The terrain of this type can be seen in Patagonia (far South South America), Norway, North Canada and Siberia. All these areas were covered with ice leaves during the recent ice age, more than 10,000 years ago. Only when the ice leaves retreated could these areas colonize humanity.

Ice leaves are an environment to a large extent of sterile life. Although ice leaves are made of nothing but frozen water, they tend to be very dry and provide the life of the low humidity on which they are doing. They cover the ground and prevent the accumulation of soil rich in nutrients. The only forms of life that really make their ice leaves are microbes that live on rocks peeking out of ice, blown there by the wind. Tips koPC or mountains that protrude from ice leaves are called nunataks.

The earth had no ice leaves around the poles. In fact, such a circumstance is relatively atypical. For most of the country's history, the climate was warm enough that ice leaves were not formed around the poles and the forests stretched from pole to pole. Dinosaurs fossils were even found less than 10 degrees from the South Pole.
