| Terms for subject Environment (5171 entries) |
| tropical forest ecosystem (The interacting system of a biological community and its non-living environmental surroundings in forests found in tropical regions near the equator, which are characterized by warm to hot weather and abundant rainfall) | tropisk regnskogøkosystem | |
| tropical plant (Plants growing in tropical areas in conditions of constant rain and high temperature) | tropisk plante | |
| tropical rain forest (The most valuable and the richest ecosystem on Earth. It plays a critical part in the Earth's life support systems and house 50%, and possibly as much as 90%, of all the species on Earth. It is a key storehouse of foods, oils and minerals, and a source of ingredients that make up a range of medical treatments. It also represents home and livelihood for many people. However, more than half of the rainforests have disappeared, chopped down for valuable tropical hardwoods, or cleared to provide areas for cattle grazing or human habitation. The forests play an important part in climate patterns, and deforestation is thought to be responsible for 18% of global warming. Furthermore, as they disappear there is also an albedo effect - a damaging increase in the sunlight reflected - which affects wind and rainfall patterns) | tropisk regnskog | |
| tropics (The region of the earth's surface lying between two parallels of latitude on the earth, one 23°27' north of the equator and the other 23°27' south of the equator, representing the points farthest north and south at which the sun can shine directly overhead and constituting the boundaries of the Torrid Zone) | tropene | |
| troposphere (The lowest of the concentric layers of the atmosphere, occurring between the Earth's surface and the tropopause. It is the zone where atmospheric turbulence is at its greatest and where the bulk of the Earth's weather is generated. It contains almost all the water vapour and aerosols and three-quarters of the total gaseous mass of the atmosphere. Throughout the troposphere temperature decreases with height at a mean rate of 6.5°C/km and the whole zone is capped by either an inversion of temperature or an isothermal layer at the tropopause) | troposfære | |
| tropospheric ozone (Tropospheric ozone is a secondary pollutant formed from emissions of nitrogen oxides, non-methane volatile organic compounds and carbon monoxide. Ozone scars lung tissue, makes eyes sting and throats itch. It has been implicated as a contributor to forest dieback, damage to agricultural crops, etc.) | bakkenært ozon | |
| trunk road (A main road, especially one that is suitable for heavy vehicles) | hovedveg | |
| tumour (Any new and abnormal growth, specifically one in which cell multiplication is uncontrolled and progressive) | svulst | |
| tundra (An area supporting some vegetation (lichens, mosses, sedges and low shrubs) between the northern upper limit of trees and the lower limit of perennial snow on mountains, and on the fringes of the Antarctic continent and its neighbouring islands) | tundra | |
| tunnel (A underground passageway, especially one for trains or cars that passes under a mountain, river or a congested urban area) | tunnel | |
| turbidity (Cloudy or hazy appearance in a naturally clear liquid caused by a suspension of colloidal liquid droplets or fine solids) | turbiditet | |
| turbine (A fluid acceleration machine for generating rotary mechanical power from the energy in a stream of fluid) | turbin | |
| tween-deck tanker ('between deck tanker'; A sea-going vessel that includes space between two continuous floor-like surfaces or platforms, which is also designed for bulk shipments of liquids or gases) | mellomdekk-tanker | |
| twin-hull craft (Oil tank vessels provided with a double-hull to meet the regulatory safety requirements in oil transportation. Requirements include minimum values for depths and breadth of double bottoms. Also called double-hull tank vessel) | katamaran | |
| two-stroke engine (An internal combustion engine whose cycle is completed in two strokes of the piston) | totaktsmotor | |
| type of business (The class or category of an enterprise or organization involved in an economy) | virksomhetstype | |
| type of claim (A class or category of interests or remedies recognized in law or equity that create in the holder a right to the interest or its proceeds, typically taking the form of money, property or privilege) | klageart | |
| type of management (The different, specific methods of business administration) | forvaltningstype | |
| type of tenure (The manner in which land is owned and possessed, i.e. of title to its use) | eierskapsform i landbruket | |
| type of waste (A grouping by type of unusable material left over from any process) | avfallskategori |
