| Term | Definition |
|---|---|
| precipitation | rain, snow, sleet, or hail that falls to the ground |
| drought | a prolonged period of abnormally low rainfall, leading to a shortage of water |
| humidity | the state of having relatively high level of water vapor in the atmosphere |
| atmospheric pressure | the pressure exerted by the weight of the atmosphere |
| latitude | the distance of a place north or south of the earth's equator, usually expressed in degrees and minutes |
| adhesion | the sticking together of particles of different substances |
| longitude | the distance of a place east or west of the prime meridian, usually expressed in degrees and minutes |
| severe weather | the dangerous effects created by these changes in the atmosphere that result in tornadoes, extreme thunderstorms or blizzards |
| transpiration | the process in which plants release the water inside it in the form of moisture or water vapor |
| cohesion | the intermolecular attraction by which the elements of a body are held together |
| convection | the process of heat transfer by the actual motion of matter |
| downdraft | a downward current of air |
| tornado | a mobile, destructive vortex of violently rotating winds having the appearance of a funnel-shaped cloud and advancing beneath a large storm system |
| updraft | an upward current of air |

| climate | the weather conditions prevailing in an area in general or over a long period |
| hygrometer | an instrument for measuring the humidity of the air or a gas |
| water cycle | the cycle of processes by which water circulates between the earth's oceans, atmosphere, and land, involving precipitation as rain and snow, drainage in streams and rivers, and return to the atmosphere by evaporation and transpiration |
| surface tension | the tension of the surface film of a liquid caused by the attraction of the particles in the surface layer by the bulk of the liquid |
