| Terms for subject Environment (5949 entries) |
| oxigeno-eduki | oxygen content (Amount of oxygen contained in a solution) | |
| oxigeno-falta | oxygen deficiency (No definition needed) | |
| Ozeania | Oceania (The islands of the southern, western and central Pacific Ocean, including Melanesia, Micronesia, and Polynesia. The term is sometimes extended to encompass Australia, New Zealand, and the Malay Archipelago) | |
| ozeano | ocean (The mass of water occupying all of the Earth's surface not occupied by land, but excluding all lakes and inland seas) | |
| Ozeano Antartiko | Antarctic Ocean (The waters, including ice shelves, that surround the continent of Antarctica, which comprise the southernmost parts of the Pacific, Atlantic and Indian oceans, and also the Ross, Amundsen, Bellingshausen and Weddell seas) | |
| Ozeano Artiko | Arctic Ocean (The smallest and most poorly studied of the oceans on earth. It covers an area of 14 million square km that is divided by three submarine ridges, i.e. the Alpha Ridge, the Lomonosov Ridge, and an extension of the mid-Atlantic ridge. It is also nearly landlocked, covered year-round by pack ice, and the third of its area is continental shelf) | |
| ozeano-zirkulazio | ocean circulation (Water current flow in a closed circular pattern within an ocean) | |
| ozeanografia | oceanography (The scientific study and exploration of the oceans and seas in all their aspects) | |
| ozeanografia fisiko | physical oceanography (The study of the physical aspects of the ocean, the movements of the sea, and the variability of these factors in relationship to the atmosphere and the ocean bottom) | |
| ozeanografia kimiko | chemical oceanography | |
| ozentasun | loudness (The magnitude of the physiological sensation produced by a sound, which varies directly with the physical intensity of sound but also depends on frequency of sound and waveform) | |
| ozonizazio | ozonization (The process of treating, impregnating or combining with ozone) | |
| ozono | ozone (An allotropic form of oxygen containing three atoms in the molecule. It is a bluish gas, very active chemically, and a powerful oxidizing agent. Ozone is formed when oxygen or air is subjected to a silent electric discharge. It occurs in ordinary air in very small amounts only) | |
| ozonoa urritzeko ahalmen | ozone depletion potential (A factor that reflects the ozone depletion potential of a substance, on a mass per kilogram basis, as compared to chlorofluorocarbon-11 (CFC-11). Such factor shall be based upon the substance's atmospheric life time, the molecular weight of bromine and chlorine, and the substance's ability to be photolytically disassociated, and upon other factors determined to be an accurate measure of relative ozone depletion potential) | |
| ozonosfera | ozone layer (The general stratum of the upper atmosphere in which there is an appreciable ozone concentration and in which ozone plays an important part in the radiative balance of the atmosphere) | |
| ozonosferaren urritze | ozone layer depletion (The fragile shield of ozone is been damaged by chemicals released on earth. The main chemicals that are depleting stratospheric ozone are chlorofluorocarbons which are used in refrigerators, aerosols, and as cleaners in many industries, and halons, which are used in fire extinguishers. The damage is caused when these chemicals release highly reactive forms of chlorine and bromine. Over the past 30 years ozone levels over parts of Antarctica have dropped by almost 40% during some months and a "hole" in ozone concentrations is clearly visible in satellite observations) | |
| padura | mud flat (A relatively level area of fine silt along a shore (as in a sheltered estuary) or around an island, alternately covered and uncovered by the tide, or covered by shallow water) | |
| padura | salt marsh (Areas of brackish, shallow water usually found in coastal areas and in deltas. There are also inland marshes in arid areas where the water has a high salt level because of evaporation. They are environmentally delicate areas, extremely vulnerable to pollution by industrial or agricultural chemicals, or to thermal pollution, which often results when river water has been used as the coolant in power stations and industrial plants) | |
| paisaia | landscape (The traits, patterns, and structure of a specific geographic area, including its biological composition, its physical environment, and its anthropogenic or social patterns. An area where interacting ecosystems are grouped and repeated in similar form) | |
| paisaia babesteko politika | landscape conservation policy |
