Die Permafrost soils are by no means alone Set requirement like glaciers or that eternal ice. One can certainly think about that layer of earth and Vegetation condition. This thawing shift is between 30 centimeters and two meters thick and thaws in summer. However, the permafrost below is frozen. You can 1.5 kilometers deep are sufficient. By definition they must frozen for at least two consecutive years be.
Permafrost in the subsoil: Permafrost soils such as this one in Alaska are mostly found in northern latitudes and cold climate zones, such as high mountains.

Most permafrost comes in Siberia, Canada and Alaska before, but also in China, Scandinavia and other regions. In Germany there is only one permafrost ground, namely on the Zugspitze. Most of the permafrost comes from the last ice age before 10.000 bis 20.000 years.
If climate change continues at this pace, researchers assume that it will be before the end of this millennium 75 percent of permafrost could melt. They then usually turn into one swampland. However, this also makes loads more problematic greenhouse gases such as methane or CO2 released that were previously bound.
People are increasingly settling in these areas, especially since they are increasing here raw materials be uncovered, which can now be promoted.
Again and again are in the floors frozen animals like mammoths found – not only their bones, but also fur, wool, blood or flesh. The following video from the Alfred Wegener Institute (AWI) explains the permafrost and its thawing more accurate.
