Hot springs are common on the surface of the Earth.World renown acquired geysers of Kamchatka, Iceland and Yeloustounskogo National Park.Yes, and many other places where access to the surface of the hot and warm water is more "peaceful" and calm way, are well known not only in the countries where they are located, but also far beyond.
Many hot springs have healing properties.This is due to the fact that they reach the surface, hot water dissolves some encounters rocks rich in beneficial to the human elements and minerals.
Most of these sources is related to the volcanic activity.They are typically located in a seismically active area where the underground fire comes close to the Earth's surface.Often in places where the hot water treatment facilities are located.These are the Caucasian Mineral Waters, spa resorts of southern China, Italy and resorts in Bulgaria.
Thermal sources, depending on the composition of the water used for the treatment of various diseases.Potassium and sodium can help in diseases of the respiratory system, skin and nervous system.A radon springs are good for the treatment of the musculoskeletal system: rheumatism, sciatica, joint disease.Composition hot springs may vary (depending on which species predominate at the exit point of water at the surface).
Water from these sources can be used both for ingestion and for bathing.In most cases, the correct dosage or to select the method of application of water is necessary to consult a doctor.At a temperature of hot springs are divided into warm (with a water temperature of twenty - thirty-seven degrees above zero Celsius), hot (thirty-seven - fifty degrees) and very hot (above fifty degrees).
Interestingly, some hot springs are located away from the seismically active regions.In these cases, the water comes from a great depth.For each kilometer of depth the temperature of the rocks that make up Earth's crust rises to thirty degrees.Therefore, wherever there are cracks in the crust, leaving a depth of more than a kilometer, and there may be hot springs.Tyumen is located in a seismic zone completely inert, perfectly proves the rule.In the Urals and Western Siberia is widely known and popular resorts located in the area of Tyumen and Yalutorovsk.
thermal source can be used not only for health purposes.In 1967, work began the world's first geothermal power plant.It was Paratunskaya GeoPP Kamchatka.Now the power of this type (except Russia) is in twenty-three countries on all continents.Do Geothermal Power Plant has a big advantage over other power plants: they do not depend on the environmental conditions and is not used for the production of electricity of non-renewable resources.One would think: that's it, ecologically and economically perfect source of energy!But not all so simple.Although economically GeoPP indeed very beneficial to the environment but often not all so rosy as it seems at first glance.
fact that the hot water used in geothermal power stations, often contain a variety of substances that are harmful to humans and animals.In particular, salts of certain metals it.Therefore, the used water can not be discharged into the water bodies of the Earth surface.From the position reached by pumping waste water back into the aquifer.
