weather quiz Flashcards
water cycle
Liquid water evaporates into the air and becomes water vapor, condenses into liquid water, falls back down as precipitation
humidity
the measure of the amount of water vapor in the air
relative humidity
the percentage of water vapor in the air compared to the maximum amount of water vapor that the air can hold
psychrometer
a tool that measures relative humidity by being spun around and seeing the temperature difference between the wet bulb and dry bulb because of water evaporating from the wet bulb
dew point
the temperature at which condensation begins
cirrus
thin, wispy clouds very high in the atmosphere- indicate good weather
cumulus
cottony clouds that form kinda close to the ground- cumulonimbus are cumulus clouds that are very tall and mean thunderstorms
stratus
flat layer clouds that cover the whole sky- dull gray color- nimbostratus produces drizzle, rain or snow
nimbo
clouds that produce precipitation
evapotranspiration
plants opening up their pores and releasing water
precipitation
any form of water that falls from clouds and reaches Earth’s surface
freezing rain
raindrops fall as liquid, touch cold surface and freeze
snow
water vapor condenses to ice crystals when dew point is below freezing and fall as snow
sleet
raindrops fall through a layer of air below freezing and freeze
hail
ice pellets that are carried around in the air and gain a new layer of ice when it goes through a cold region
