| Term | Definition |
|---|---|
| Weather | the state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain, etc. |
| Greenhouse 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. |
| Global Warming | 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, chlorofluorocarbons, and other pollutants. |
| Ozone | a colorless unstable toxic gas with a pungent odor and powerful oxidizing properties, formed from oxygen by electrical discharges or ultraviolet light. It differs from normal oxygen (O2) in having three atoms in its molecule (O3). |
| Climate | the weather conditions prevailing in an area in general or over a long period. "our cold, wet climate" |
| Sustainability | the ability to be maintained at a certain rate or level. |
| resource | a stock or supply of money, materials, staff, and other assets that can be drawn on by a person or organization in order to function effectively. |
| Renewable resource | A renewable resource is a resource which can be used repeatedly because it is replaced naturally. |
| Non renewable resource | A nonrenewable resource is a resource of economic value that cannot be readily replaced by natural means on a level equal to its consumption. |
| Biodegradable | (of a substance or object) capable of being decomposed by bacteria or other living organisms. |
| Non-biodegradable | Waste and pollution. a substance or chemical that is non-biodegradable cannot be changed to a harmless natural state by the action of bacteria, and may therefore damage the environment |
| Composting | make (vegetable matter or manure) into compost. |
| Migration | movement from one part of something to another. |
| Emission | the production and discharge of something, especially gas or radiation. |
| Absorption | the process or action by which one thing absorbs or is absorbed by another. |
| EM Spectrum | the range of wavelengths or frequencies over which electromagnetic radiation extends. |
| Troposphere | the lowest region of the atmosphere, extending from the earth's surface to a height of about 3.7-6.2 miles (6-10 km), which is the lower boundary of the stratosphere. |
| Mesosphere | the region of the earth's atmosphere above the stratosphere and below the thermosphere, between about 30 and 50 miles (50 and 80 km) in altitude. |
| Stratosphere | the layer of the earth's atmosphere above the troposphere, extending to about 32 miles (50 km) above the earth's surface (the lower boundary of the mesosphere). |
| Thermosphere | the region of the atmosphere above the mesosphere and below the height at which the atmosphere ceases to have the properties of a continuous medium. The thermosphere is characterized throughout by an increase in temperature with height. |
| Conduction | the process by which heat or electricity is directly transmitted through a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material. |
| Albedo | the proportion of the incident light or radiation that is reflected by a surface, typically that of a planet or moon. |
| Natural resources | materials or substances such as minerals, forests, water, and fertile land that occur in nature and can be used for economic gain. |
| River Delta | A river delta is a landform that forms from deposition of sediment carried by a river as the flow leaves its mouth and enters slower-moving or standing water |
| Tsunami | a long high sea wave caused by an earthquake, submarine landslide, or other disturbance. |
