- 2. effect the trapping of the sun's warmth in a planet's lower atmosphere, due to the greater transparency of the atmosphere to visible radiation from the sun than to infrared radiation emitted from the planet's surface.
- 4. the process of adapting to something (such as environmental conditions)
- 5. change a change in global or regional climate patterns, in particular a change apparent from the mid to late 20th century onwards and attributed largely to the increased levels of atmospheric carbon dioxide produced by the use of fossil fuels.
- 9. a gradual increase in the overall temperature of the earth's atmosphere generally attributed to the greenhouse effect caused by increased levels of carbon dioxide, CFCs, and other pollutants.
- 10. the complex of living organisms, their physical environment, and all their interrelationships in a particular unit of space. An ecosystem can be categorized into its abiotic constituents, including minerals, climate, soil, water, and sunlight, and its biotic constituents, consisting of all living members.
- 11. the envelope of gases surrounding the earth or another planet:
Down
- 1. a colourless, odourless gas produced by burning carbon and organic compounds and by respiration. It is naturally present in air (about 0.03 per cent) and is absorbed by plants in photosynthesis.
- 3. in biology, is the dying out or extermination of a species. It occurs when species are diminished because of environmental forces (natural or human-made) or because of evolutionary changes in their members.
- 6. fuels are a non-renewable source of energy. Most of the energy used by us is obtained by the burning of fossil fuels. These fossil fuels are used up at a faster rate. They cannot be regrown at a scale compared to their consumption.
- 7. the weather conditions prevailing in an area in general or over a long period.
- 8. the production and discharge of something, especially gas or radiation:
