| 11398548109 | climate | The average weather conditions in an area over a long period of time | 1 | |
| 11398548110 | front | A boundary between two air masses | 2 | |
| 11398548111 | Coriolis effect | Causes moving air and water to turn left in the southern hemisphere and turn right in the northern hemisphere due to Earth's hemisphere. | 3 | |
| 11398548112 | prevailing winds | Global winds that blow constantly from the same direction | 4 | |
| 11398548113 | Upwelling | the upward movement of ocean water toward the surface as a result of diverging currents | 5 | |
| 11398548114 | greenhouse gases | Gases such as carbon dioxide, methane, nitrous oxide, water vapor, and ozone in the atmosphere which are involved in the greenhouse effect. | 6 | |
| 11398548115 | greenhouse effect | warming that results when solar radiation is trapped by the atmosphere | 7 | |
| 11398548116 | Microclimate | environmental conditions within a small area that differs significantly from the climate of the surrounding area | 8 | |
| 11398548117 | rain shadow effect | Low precipitation on the far side (leeward side) of a mountain when prevailing winds flow up and over a high mountain or range of high mountains. This creates semiarid and arid conditions on the leeward side of a high mountain range. | 9 | |
| 11398548118 | El Nino | (oceanography) a warm ocean current that flows along the equator from the date line and south off the coast of Ecuador at Christmas time | 10 | |
| 11398548119 | La Nina | A cooling of the ocean surface off the western coast of South America, occurring periodically every 4 to 12 years and affecting Pacific and other weather patterns. | 11 | |
| 11398548120 | Southern Oscillation | the atmospheric pressure conditions corresponding to the periodic warming of El Nino and cooling of La Nina. | 12 | |
| 11398548121 | atmosphere | A mixture of gases that surrounds a planet or moon. | 13 | |
| 11398548122 | Troposphere | The lowest layer of Earth's atmosphere | 14 | |
| 11398548123 | Stratosphere | 2nd layer of atmosphere; extends from 10 to 30 miles up; location of ozone layer; absorbs 95% of Ultraviolet radiation; temperature increases with altitude increase. | 15 | |
| 11398548124 | global warming | An increase in the average temperature of the earth's atmosphere (especially a sustained increase that causes climatic changes) | 16 | |
| 11398548125 | air pollution | the contamination of the atmosphere by the introduction of pollutants from human and natural sources | 17 | |
| 11398548126 | primary pollutants | pollutants that are put directly into the air by human or natural activity. | 18 | |
| 11398548127 | secondary pollutants | pollutants that are formed by the combination of primary pollutants in the atmosphere. | 19 | |
| 11398548128 | photochemical smog | A brownish haze that is a mixture of ozone and other chemicals, formed when pollutants react with each other in the presence of sunlight | 20 | |
| 11398548129 | industrial smog | smog resulting from emissions from industry and other sources of gases produced by the burning of fossil fuels. | 21 | |
| 11398548130 | temperature inversion | atmospheric condition in which warm air traps cooler air near the earth's surface | 22 | |
| 11398548131 | acid deposition | caused by sulfuric and nitric acids resulting in lowered pH of surface waters | 23 | |
| 11398548132 | pH | Scale used to specify acidity or basicity | 24 | |
| 11398548133 | ozone depletion | The breakdown of the ozone layer caused by chlorofluorocarbon. | 25 | |
| 11398548134 | acid deposition | caused by sulfuric and nitric acids resulting in lowered pH of surface waters | 26 | |
| 11398548135 | brown-air smog | brown photochemical smog from car exhaust from NOx | 27 | |
| 11398548136 | thermal inversion | A situation in which a relatively warm layer of air at mid-altitude covers a layer of cold, dense air below. | 28 |
