These incredible pictures like views of another planet from a bird's flight. In fact, it's pictures of hot springs in Iceland, taken at very close range.
The hot springs - thermal springs - an underground water that comes out of the ground and has a temperature higher than the average temperature in the area. All mineral sources are divided into warm - water temperature at which 20-37 degrees, 37-50 degrees, and hot hypothermal very hot with temperatures of 50 degrees and above.
The isotherm of 20 ° C (temperature equal space) in the crust extends to a depth of 1,500-2,000 m (permafrost regions) to 100 m or less (subtropics) and in the tropics comes to the surface.
Thermal water also used for heating and as an alternative source of electricity. Reykjavik (capital Iceland) fully heated heat of thermal water.
In Italy, Iceland, Mexico, Russia, the USA and Japan is working on a number of power plants superheated thermal waters with a temperature of over 100 ° C
For example, in Iceland there is a hot spring Deyldartungyukver in which water is 97 degrees year round, it is the largest thermal spring in Europe, which is more economic assistance and brings. Hot water from the heat source can be at home, which is what in Iceland.
The majority of hot springs feed water, which is heated by magmatic intrusions in areas of active volcanism.
However, not all thermal sources are attached to such areas, the water can also be heated convective circulation - groundwater seeping down reach a depth of about one kilometer or more, where the rock has a higher temperature due to the geothermal gradient of the earth's crust is about 30 ° C km on the first 10 km.
The hot springs since ancient times been used for the treatment of patients (Roman, Tbilisi terms), corresponding to a branch of medicine called wellness.
known resorts Belokurikha Kuldur (nitrogen baths, rich in silica), the Caucasian Mineral Waters (carbonated water), Matsestinsky Resort (hydrogen sulfide) are located on the territory of Russia.
The composition of the mineral water in the springs is different, it depends on the soil, gases, soil that seeps through and simultaneously enriched water. Which contains almost the entire periodic table.
