What is the klatrat?

The type of hydrate or water compound in which the molecules of other substances are captured within a cage similar to a structure composed of water molecules. The trapped molecule is usually gas at normal pressure and temperature. The valleys are ice solids that are generally formed at high pressures and low temperatures. Among the best known and best known is methane hydrate, which occurs naturally in large deposits under the seabed in many parts of the world. It may be a potential source of energy, but there is also concern that the sudden release of large quantities of valve methane, perhaps induced by global warming, could be disastrous. The structure is essentially held together by hydrogen bonds between water molecules, but stabilized by guest molecules. From the DodeCahedra, it is not possible to pack together to fill in all available spaces, and other polyhedral shapes also occur, creating a grille. Due to this change of cage shapes and the fact that not all cages are necessarily occupied, nelto give precise chemical formulas from the klatrats. Molecules of the visiting valve can be hydrocarbon gases such as methane or ethane, oxygen, nitrogen and carbon dioxide.

Methane hydrate is a compound of a valve that generated the greatest interest. This compound occurs in large quantities at different places around the edges of all continents and in the permafrost areas of Siberia and Alaska. It is estimated that these deposits are the largest hydrocarbon reserve on the planet, which far exceeds known coal, oil and natural gas reserves. It is assumed that they have been formed from methane produced by microbial activity in anaerobic conditions in sediments just below the seabed surface or on the ground where temperatures are low enough. Even in tropical areas, the temperatures of the seabed are sufficiently low for the formation of the callers, where the pressure allows them to solidify several degrees above the freezing point.

Due to the hugeThe amount of methane stored in these bearings was considered a potential source of natural gas. However, there may be serious technical problems associated with its extraction, which makes it uneconomical. During the 1960s and 1970s, the Soviet Union has made a number of unsuccessful attempts to extract gas from the Siberian permafrost. There are also concerns that the methods used to release the captured gas can destabilize deposits, which could potentially lead to land and landslides.

Although the deposits of the valve may be a huge unused energy resource, they can also pose a serious risk. They are not stable out of the temperature and prisons of Esen where they occur, and there is concern that global warming can make them unstable. This represents a double threat.

First, the melting of ice valleys mixed with sediments on the continental edges could lead to massive landslides and subsequent tsunami. There are a cut out of a relatively recent geological pastAzy that this could have happened off the coast of Norway. Second, methane is a strong "greenhouse" gas that captures heat in the atmosphere even greater than carbon dioxide. Sudden release of a huge amount of gas could speed up global warming, which in turn could cause further destabilization. Again, there is geological evidence that this could have occurred in the past through natural processes and since 2011 there has been special concerns about methane hydrate in permafrost deposits.
