| watercycle | the movement of water between the atmoshere, land, ocean, and even living things. |
| evaporation | occurs when liquid water changes into vapor. Ex. boiling water evaporates. |
| transpiration | the release of water vapor into the air by plants. |
| sublimation | when solid water changes directly to water vapor without first becoming a liquid. |
| condensation | is the change of state from a gas to a liquid. |
| precipitation | is any form of water that falls to Earth from clouds. |
| weather | is the condition of Earth's atmosphere at a certain time place. |
| humidity | the amount of water vapor in the air. |
| relative humidity | is the amountof water vapor needed to reach saturation. |
| dewpoint | is the temperature at which more condensation than evaparation occurs. |
| air pressure | is the force of air molecules pushing on an area. |
| wind | is air that moves horizontally, or parallel to the ground. |
| visibility | is a measure of the didtance at which an object or light can be clearly seen. |
| air mass | is a large volume of air in which temperature and moisture cintent are nearly the same throughout. |
| frount | a boundary that forms between the air masses. |
| jet stream | long distance words that travel above global winds that travel for thousands of kilometers. |
| thunderstorm | is an intense local storm that forms strong winds, heavy rain, lighting, thunder, and sometimes hail. |
| lighting | is an electric discharge that happens between a positively charged area and a negatively charged area. |
| hurricane | is a tropical low-pressure system with winds blowing at speeds of 119 km/h (74m/h) or more strong enough to uproot trees. |
| thunder | the sound created by the rapid expansion of air along a lighting strike. |
| storm surge | a huge mass of ocean water as a result of a hurricane moving into a coastal area. |
| tornado | is a destructive rotating column of air that has very high windspeeds and that is sometimes visible as a funnel-shaped cloud. |
| sinkhole | are holes in the ground that from when caves collapse. |
| muck fire | muck fire are fires that burn underground. |
| wildfire | a large fire that spreads quickly over woodland. |
| weather | the short-termstate of the atmosphere, including temperature, humidity, precipitation, wind, and visibility. |
| climate | the weather in an area over a long time. |
| latitude | the angular distance in degrees north to south from the equator. |
| topography | the surface features of an area. |
| elevation | refers to the height of an area above sea level |
| surface currents | currents on the surface of the ocean. |
| Temperature..... | .....ranges are a better indication of climate than are temperature averages. |
| Precipitation..... | .....patterns are a better indicator of lacal climate than the average precipation alone. |
| Climate..... | .....is determined by temperature and precipitation. |
