Terms for subject Environment (7005 entries)

těkavost	volatility (The property of a substance or substances to convert into vapor or gas without chemical change)
těkavá organická sloučenina	volatile organic compound
těleso topné	heater (An apparatus that heats or provides heat)
tělo lidské	human body (The entire physical structure of an human being)
těsnění tělesa skládky	landfill base sealing (Sealing of a landfill with a relatively impermeable barrier designed to keep leachate inside. Liner materials include plastic and dense clay)
těžba	extraction (Any process by which a pure metal is obtained from its ore)
těžba štěrkopísku	gravel extraction (Obtaining a mixture of coarse sand and small water- worn or pounded stones, (used for paths and roads and as an aggregate) from the earth)
těžba štěrku	aggregate extraction (Extraction of crushed rock or gravel screened to sizes for use in road surfaces, concretes, or bituminous mixes)
těžba dřeva	cutting (The act or process of felling or uprooting standing trees, in order to produce timber products; forestry)
těžba dřeva	forest exploitation (Forests have been exploited over the centuries as a source of wood and for obtaining land for agricultural use. The mismanagement of forest lands and forest resources has led to a situation where the forest is now in rapid retreat. The main aspects of the situation are: serious shortages in the supply of industrial wood; the catastrophic erosion and floods accompanying the stripping of forests from mountainous land; the acute shortages of fuel wood in much of the developing world; the spread of desert conditions at an alarming rate in the arid and semi-arid regions of the world; and the many environmental effects of the destruction of tropical rainforests)
těžba lignitu	lignite mining (Extraction of brown coal from natural deposits; lignite is a brownish-black solid fuel in the second stage in the development of coal. It has a little over half the heating value of bituminous or anthracite coal)
těžba na moři volném	deep sea mining (The most valuable of the marine mineral resources is petroleum. About 15% of the world's oil is produced offshore, and extraction capabilities are advancing. One of the largest environmental impacts of deep sea mining are discharged sediment plumes which disperse with ocean currents and thus may negatively influence the marine ecosystem. Coal deposits known as extensions of land deposits , are mined under the sea floor in Japan and England)
těžba plynu zemního	natural gas extraction (The tapping of natural gas from wells located under the sea and in general from underground sources often in association with petroleum deposits; it is used as a fuel, having largely replaced coal-gas for this purpose, and as a source of intermediates for organic synthesis)
těžba povrchová	opencast mining (Extracting metal ores and minerals that lie near the surface by removing the overlying material and breaking and loading the ore)
těžba povrchová	strip mining (Superficial mining, in which the valuable rock is exposed by removal of overburden. Coal, numerous nonmetals and metalliferous ores (iron and copper) are worked in this way. Sinonym: strip mining, opencast mining, openpit mining)
těžba písku	sand extraction (The extraction of sand by mining for building purposes and for the extraction of heavy minerals such as rutile and zircon)
těžba rašeliny	peat extraction (Peat is obtained from peat bogs by cutting it from the earth; it is then formed into briquettes, which can be used as fuel. Peat may be found in layers several metres thick. In some countries peat-fired generating stations for electricity are in use. Peat is also used as a soil conditioner)
těžba ropy	oil extraction (Recovery of oil by surface mining, as in tar sands or oil shales, or from tunnels in a shallow reservoir)
těžba ropy v moři volném	offshore oil drilling (The act or process of extracting petroleum from deposits underlying the floor of the ocean or some other large body of water)
těžba soli kamenné	rock salt mining (Rock salt mining is an underground mining process in which the salt is physically dug out of the ground in an operation involving drilling, blasting and crushing the rock. The major percentage of this output is used for winter road maintenance)
