8th Science CH8 Weather
| Term | Definition |
|---|---|
| air mass | large body of air whose temperature and amount of moisture result from the type of surface over which it developed; day-to-day changes in the weather are caused by the movement and collision of air masses |
| dew point | temperature at which the water vapor in saturated air begins to condense |
| front | boundary resulting from the collision between moving air masses, producing such weather events a rain, snow, or violent storms |
| hurricane | intense, highly destructive storm formed from a swirling, low pressure system over a warm, moist tropical ocean; hurricanes are very large, have high winds that can be accompanied by torrential rain, and weaken as they strike land |
| relative humidity | measure, expressed as a percentage, between the amount of water vapor in the air, and the total amount of water vapor the air can hold at that specific temperature |
| saturated | 100 percent relative humidity in the air; occurs when air cannot hold additional moisture at a specific temperature |
| tornado | violent, funnel-shaped storm formed from a low pressure system; tornadoes are highly destructive, short-lasting, and move over land in a narrow path |
