Digital GlossaryGlobal Warming &Greenhouse EffectG-Z
GGlobal warming: an increase in world temperatures, caused by an increase in carbon dioxide around the Earth.
Glaciers: persistent bodies of ice formed by the accumulation of snow.
Gas: one of the three fundamental states of matter; a substance such as air, which is not solid or liquid.
Greenhouse: a glass building used for growing plants.
Greenhouse effect: the warming of the air around the Earth as a result of the Suns heat being trapped by pollution.
Greenhouse gases: gases released in the atmosphere that absorb and emit radiation.
HHuman activity: human work that contributes to upset the balance of the carbon cycle.
Heat: an increase in temperature.
Hot: having a high temperature.
IInfra-red: infra-red light gives out heat but cannot be seen. Infrared radiation (I.R.): electromagnetic radiation with longer wavelenghts than those of visible light.
Imbalance: when two things are not the right size in relation to each other.
MMethane: a chemical compound, the main component of natural gas and also a greenhouse gas.
Minimize temperature increase: to diminish the temperature of the Earth.
NNatural causes: happenings produced by nature.
Natural greenhouse gases: gases originated in nature, which cushion the earths surface, causing a global heat increase.
OOzone: an unstable, poisonous allotrope of oxygen, that is formed naturally in the ozone layer. It is made up of 3 atoms of oxygen.
Ozone layer: it is a layer in the Earths atmosphere containing high concentrations of ozone. This layer absorbs ultra-violet radiation.
Ozone hole: it is an annual thinning of the ozone layer over the Antarctic, caused by stratospheric chlorine.
PPollutants: substances which contaminate the atmosphere with undesired effects.
Predictability: something behaving or happening in the way that you expect.
Pollution: damage caused to air, water, soil, by harmful chemicals and waste.
Recycle: to extract useful materials from garbage or waste.
Reduce: to limit, to decrease the quantity of something. R
SSea levels: the levels of the ocean surface used as a standard in reckoning with land elevation or sea depths.
Storm: a period of very bad weather with heavy rain, strong wind, and often lightning.
WWeather: condition of the atmosphere at a certain place and time, with reference to temperature and the presence of rain, sunshine, wind.
Warm: slightly hot, especially in a pleasant way.
