32 terms
Terms | Definitions |
|---|---|
 glaze | supercooled water that freezes when it touches a solid |
| sleet | tiny clear translucent ice particles |
| ozone | made up of 3 oxygen atoms that are bonded together |
| troposphere | layer of atmosphere that contains weather |
| thinnest layer of the atmosphere | thermosphere |
| most abundant gas in the atmosphere | nitrogen |
| most abundant - least abundant | nitrogen, oxygen, argon, CO2, other |
| tropopause | seperates the troposphere from the stratosphere |
| hot seatbelt against skin | conduction |
| earth receives energy fron the sun | radiation |
| higher elevations | lower temperatures |
| isotherms | lines that connect points of equal temperature |
| rain, snow, sleet, and hail | precipitation |
| solid-gas | sublimation |
| gas-solid | deposition |
| air that has reached its water vapor capacity | saturated |
| can hold more water | warm air |
| dew point | temperature that air must reach in order to reach saturation |
| examples of condensation nuclei | salt, ash, dust, crystals, soil |
| cumulus clouds | cotton-like and puffy |
| nimbostratus clouds | low and produce rain |
| prefix alto | middle height clouds |
| fog vs. clouds | fog is at ground level, clouds can produce rain |
| supercooled water | water is liquid below its freezing point |
| isobars | lines that connect points of equal air pressure |
| weather in high pressure system | clear |
| closely spaced isobars indicate | steep pressure gradient and high winds |
| winds of a high pressure system | blow clockwise |
| wind influence | differences in pressure,temperature, and the Coriolis Effect |
| coriolis Effect | direction of wind |
| cyclones | low pressure,counterclockwise, clouds |
| anticyclones | high pressure, clockwise, clear skies |
