| Terms for subject Environment (6297 entries) |
| cleaning up (The process of bringing desert, marsh, sea coast or other waste or unproductive land into use or cultivation) | تطهير | |
| cleanliness (clothes, kitchenware, etc.; The state of being clean and keeping healthy conditions; hygiene) | نظافة | |
| cleansing (The act or process of washing, laundering or removing dirt and other unwanted substances from the surface of an object, thing or place) | تنظيف | |
| cleansing department (A division, usually within municipal government, responsible for providing services that remove dirt, litter or other unsightly materials from city or town property) | هيئة النظافة | |
| cleansing product | منظف | |
| clearing sludge | وحل التطهير | |
| cliff (A steep coastal declivity which may or may not be precipitous, the slope angle being dependent partly on the jointing, bedding and hardness of the materials from which the cliff has been formed, and partly on the erosional processes at work. Where wave attack is dominant the cliff-foot will be rapidly eroded and cliff retreat will take place, especially in unconsolidated materials such as clays, sands, etc., frequently leaving behind an abrasion platform at the foot of the cliff) | جُرف - منحدر صخري | |
| climate (The average weather condition in a region of the world. Many aspects of the Earth's geography affect the climate. Equatorial, or low, latitudes are hotter than the polar latitudes because of the angle at which the rays of sunlight arrive at the Earth's surface. The difference in temperature at the equator and at the poles has an influence on the global circulation of huge masses of air. Cool air at the poles sinks and spreads along the surface of the Earth towards the equator. Cool air forces its way under the lower density warmer air in the lower regions, pushing the lighter air up and toward the poles, where it will cool and descend) | مناخ | |
| climate protection (Precautionary actions, procedures or installations undertaken to prevent or reduce harm from pollution to natural weather conditions or patterns, including the prevailing temperature, atmospheric composition and precipitation) | حمايةالمناخ | |
| climate resource (No definition needed) | مصدر مناخي | |
| climate type (Weather conditions typical of areas roughly corresponding to lines of latitude) | نوعية المناخ | |
| climatic alteration (The slow variation of climatic characteristics over time at a given place. This may be indicated by the geological record in the long term, by changes in the landforms in the intermediate term, and by vegetation changes in the short term) | التذبذبات المناخية | |
| climatic change (The long-term fluctuations in temperature, precipitation, wind, and all other aspects of the Earth's climate. External processes, such as solar-irradiance variations, variations of the Earth's orbital parameters (eccentricity, precession, and inclination), lithosphere motions, and volcanic activity, are factors in climatic variation. Internal variations of the climate system, e.g., changes in the abundance of greenhouse gases, also may produce fluctuations of sufficient magnitude and variability to explain observed climate change through the feedback processes interrelating the components of the climate system) | التغير المناخي | |
| climatic effect (Climate has a central influence on many human needs and activities, such as agriculture, housing, human health, water resources, and energy use. The influence of climate on vegetation and soil type is so strong that the earliest climate classification schemes where often based more on these factors than on the meteorological variables. While technology can be used to mitigate the effects of unfavorable climatic conditions, climate fluctuations that result in significant departures from normal cause serious problems for modern industrialized societies as much as for primitive ones. The goals of climatology are to provide a comprehensive description of the Earth's climate, to understand its features in terms of fundamental physical principles, and to develop models of the Earth's climate that will allow the prediction of future changes that may result from natural and human causes) | أثر مناخي | |
| climatic experiment (Experiments conducted to estimate future climatic conditions employing modelling of the physical processes underlying climatic change and variability; also, assessments are required of uncertain future man-made inputs such as increasing atmospheric carbon dioxide and other green-house gases) | تجربة مناخية | |
| climatic factor (Physical conditions that determine the climate in a given area, e.g. latitude, altitude, ocean streams, etc.) | عامل مناخي | |
| climatic zone (A belt of the earth's surface within which the climate is generally homogeneous in some respect; an elemental region of a simple climatic classification) | منطقة مناخية | |
| climatological drought | جفاف مناخي | |
| climatology (That branch of meteorology concerned with the mean physical state of the atmosphere together with its statistical variations in both space and time as reflected in the weather behaviour over a period of many years) | علم المناخ | |
| climax (A botanical term referring to the terminal community said to be achieved when a sere (a sequential development of a plant community or group of plant communities on the same site over a period of time) achieves dynamic equilibrium with its environment and in particular with its prevailing climate. Each of the world's major vegetation climaxes is equivalent to a biome. Many botanists believe that climate is the master factor in a plant environment and that even if several types of plant succession occur in an area they will all tend to converge towards a climax form of vegetation) | الذروة |
