Across
- 4. a detailed description or representation on a map of the natural and artificial features of an area
- 6. the sudden occurrence of a violent discharge of steam and volcanic material. these can can impact on the global climate
- 7. any of the almost spherical concentric regions of matter that make up the earth and its atmosphere, as the lithosphere and hydrosphere
- 9. climate contained ______ units are almost always indoor, and with stable temperatures and humidity levels, your valuables will be better protected from damage in long-term storage
- 10. large numbers of sunspots appear, and the solar irradiance output grows by about 0.07%
- 11. the regions of the surface, atmosphere, and hydrosphere of the earth (or analogous parts of other planets) occupied by living organisms
- 13. the series of processes by which carbon compounds are interconverted in the environment, involving the incorporation of carbon dioxide into living tissue by photosynthesis and its return to the atmosphere through respiration, the decay of dead organisms, and the burning of fossil fuels
- 15. Places located at high latitudes (far from the equator) receive less sunlight than places at low latitudes (close to the equator)
- 17. the proportion of the incident light or radiation that is reflected by a surface, typically that of a planet or moon.
- 19. the process or action by which one thing absorbs or is absorbed by another
- 20. a gas that contributes to the greenhouse effect by absorbing infrared radiation, e.g., carbon dioxide and chlorofluorocarbons
- 21. Atmospheric circulation is the large-scale movement of air and together with ocean circulation is the means by which thermal energy is redistributed on the surface of the Earth
Down
- 1. a colorless gas with a sweetish odor, prepared by heating ammonium nitrate
- 2. all the waters on the earth's surface, such as lakes and seas, and sometimes including water over the earth's surface, such as clouds
- 3. a colorless, odorless gas produced by burning carbon and organic compounds and by respiration. It is naturally present in air (about 0.03 percent) and is absorbed by plants in photosynthesis
- 5. _______________ is a measure of how much heat a greenhouse gas traps in the atmosphere up to a specific time horizon, relative to carbon dioxide
- 8. Ocean currents act much like a conveyor belt, transporting warm water and precipitation from the equator toward the poles and cold water from the poles back to the tropics
- 12. a dispersion, in air, of molecules of water, especially as produced by evaporation at ambient temperatures rather than by boiling
- 14. 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
- 16. the state of the atmosphere at a place and time as regards heat, dryness, sunshine, wind, rain, etc
- 18. the weather conditions prevailing in an area in general or over a long period
