| weather | condition of earth's atmosphere over a short period of time |
| Greenhouse Effect | the earth's atmosphere traps heat in the earth to warm peope,land and water-like a greenhouse-traps the sun's heat in to plants-with out it, earht would be too cold for most living things |
| revolution | one complete orbit around the sun |
| Tropic Of Cancer | marks the boundry where direct sunlight reaches-located at 23 1/2* N |
| spring and fall eqinoxes | on these days the sun at noon appears directly over the equator-equal amounts of night and day |
| precipitation | all forms of water that fall onto the earth's surface |
| orographical precipitation | when warm,moist air is forced up when passing over high landforms-common on seacoasts-the warm air cools as it goes up and clouds form-rain or snow falls-air is cool and dry by the time it reaches the other side-deserts form on leeward side |
| evaporation | when water rises and changes into vapor |
| atmosphere | the "gas envelope" surrounding the earth that traps the sun's heat |
| rotation | one complete turn on the earth's axis |
| length of a year | 365 1/4 days |
| Tropic Of Capricorn | marks the boundry where direct sunlight reaches-located at 23 1/2* S |
| Tropical (climate zone) | low latitude zones-reaching 23 1/2* N and S of the equator-hot all year round |
| Temperate (climate zone) | middle-latitude zones-reaches from:23 1/2* N to 66 1/2* N and 23 1/2* S to 66 1/2* S-cooler than tropics, wide range of temperatures |
| Polar (climate zone) | high-latitude zones-reaches from 66 1/2* N and 66 1/2* S to the poles-bitterly cold |
| water cycle | water evaporates from oceans, lakes, and everything that gives of water vapor and condenses in the sky with other water vapor to form clouds. The clouds move and carry as much water as they can until it gets too heavy-then it rains back onto the earth |
| frontal precipitation | most common-when two air masses of different temperatures meet-warm air rises because it is less dense |
| 3 influences on climate | elevation,nearby landforms and nearby bodies of water |
| climate | term for weather patterns that an area typically experiences over a long perid of time |
| axis | an invisible line through the earth which the earth revolves along- tilted at 23 1/2* |
| leap year | February 29-comes every 4 years |
| summer and winter solstices | as the earth moves halfway around the sun, the southern hemisphere tilts closer to the sun and vise-versa-when sun appears directly over the tropics of cancer and capricorn |
| fronts | air masses |
| convectional precipitation | when hot,humid air rises and cools then losing its ability to hold much water-common in tropics |
