| Terms for subject Environment (6279 entries) |
| kaňon | canyon (A long deep, relatively narrow steep-sided valley confined between lofty and precipitous walls in a plateau or mountainous area, often with a stream at the bottom; similar to, but largest than, a gorge. It is characteristic of an arid or semiarid area (such as western U.S) where stream downcutting greatly exceeds weathering) | |
| kapradina | fern (Any of a large number of vascular plants composing the division Polypodiophyta, without flowers and fruits) | |
| karcinogen | carcinogen (A substance that causes cancer in humans and animals) | |
| karcinogenita | carcinogenicity (The ability or tendency of a substance or physical agent to cause or produce cancer) | |
| kardiologie | cardiology (The study of the heart) | |
| kartografie | cartography (The making of maps and charts for the purpose of visualizing spatial distributions over various areas of the earth) | |
| Kaspické moře | Caspian Sea (No definition needed) | |
| kaštan | chestnut (Any north temperate fagaceous tree of the genus Castanea, such as Castanea sativa, which produce flowers in long catkins and nuts in a prickly bur) | |
| katalýza | catalysis (A phenomenon in which a relatively small amount of substance augments the rate of a chemical reaction without itself being consumed) | |
| katalyzátor | catalyst (A substance whose presence alters the rate at which a chemical reaction proceeds, but whose own composition remains unchanged by the reaction. Catalysts are usually employed to accelerate reactions(positive catalyst), but retarding (negative) catalysts are also used) | |
| katalyzátor automobilový | catalytic converter (Catalytic converters are designed to clean up the exhaust fumes from petrol-driven vehicles, which are otherwise the major threat to air quality standards in congested urban streets and on motorways. Converters remove carbon monoxide, the unburned hydrocarbons and the oxides of nitrogen. These compounds are damaging to human health and the environment in a variety of ways. The converter is attached to the vehicle' s exhaust near the engine. Exhaust gases pass through the cellular ceramic substrate, a honeycomb-like filter. While compact, the intricate honeycomb structure provides a surface area of 23.000 square metres. This is coated with a thin layer of platinum, palladium and rhodium metals, which act as catalysts that simulate a reaction to changes in the chemical composition of the gases. Platinum and palladium convert hydrocarbons and carbon monoxide into carbon dioxide and water vapour. Rhodium changes nitrogen oxides and hydrocarbons into nitrogen and water, which are harmless) | |
| katastrofa | catastrophe (A sudden, widespread disaster or calamity that greatly exceeds the resources of an area or region) | |
| katastrofa | disaster (The result of a vast ecological breakdown in the relations between man and his environment, a serious and sudden event (or slow, as in drought) on such a scale that the stricken community needs extraordinary efforts to cope with it, often with outside help or international aid) | |
| katastrofa ekologická | ecocatastrophe (A sudden, widespread disaster or calamity causing extensive damage to the environment that threatens the quality of life for people living in the affected area or region, potentially leading to many deaths) | |
| katastrofa geologická | geological disaster (Disasters caused by movements and deformation of the earth's crust) | |
| katastrofa hydrologická | hydrologic disaster (Violent, sudden and destructive change either in the quality of the earth's water or in the distribution or movement of water on land, below the surface or in the atmosphere) | |
| katastrofa přírodní | natural disaster (Violent, sudden and destructive change in the environment without cause from human activity, due to phenomena such as floods, earthquakes, fire and hurricanes) | |
| katastrofa v důsledku činnosti lidské | human-made disaster (Violent, sudden and destructive change in the environment caused by man) | |
| katastrofa v důsledku vlivů povětrnostních | meteorological disaster (Violent, sudden and destructive change to the environment related to, produced by, or affecting the earth's atmosphere, especially the weather-forming processes) | |
| katastrofa zemědělská | agricultural disaster (Violent, sudden and destructive change in the environment either affecting or caused by land cultivation or the raising of crops or livestock) |
