The interaction between water vapor, wind and _ causes weather.
air temperature
drops of water that fall in temperatures above freezing
rain
forms when air temperature is below freezing and water vapor changes directly to a solid
snow
High, thin, white, feathery clouds containing ice crystals are called _ clouds.
cirrus
Masses of puffy, white clouds, often with flat bases, that form when air currents rise are called _ clouds.
cumulus
The amount of water vapor that the air is holding compared to the amount needed for saturation at a specific temperature is the ____ ______.
relative humidity
A form of precipitation that can break windows and destroy crops is ___.
hail
Low, layered gray clouds that produce drizzle or light precipitation are __ clouds.
stratus
At higher temperatures, air can hold _ water vapor as compared to air at lower temperatures.
more
When air contains as much moisture as possible at a specific temperature, it is ________ and __________.
at it's dew point and saturated.
forms when raindrops pass through a layer of freezing air near Earth's surface, forming ice pellets.
sleet
A cumulus cloud that is so full of water vapor that sunlight cannot penetrate or pass through is called __.
cumulonimbus
Clouds form as warm air rises, expands, cools and becomes saturated, and then _ condenses into tiny drops which collect.
water vapor
forms when water freezes around small ice pellets and can grow when they are tossed up and down by rising and falling air
hail
Water can form on grass in the early morning when the air is clear because __.
the air near the ground cools to its dew point
Fog is a _ cloud that forms near the ground.
stratus
If air containing moisture is cooled, the temperature at which the air is saturated and condensation forms is known as the ___.
dew point
If the air is saturated, what would you expect the relative humidity to be?
100%
When water droplets in a cloud combine, become too heavy, and fall to the ground as rain, snow, sleet or hail, we are experiencing_.
precipitation
The type of precipitation that is received on the ground depends on the __.
