person who studies weather
includes rain, snow, sleet, and hail
amount of moisture in air compared to amount needed from saturation at a given temperature
air holding all the moisture it can at a particular temperature
weather information collected by meteorologists at specific locations

What is relative humidity?
the relative humidity?
What is sleet?
rain drops that pass through a layer of freezing air near Earth's surface forming pellets
What is temperature?
a measure of the aerate amount of motion of molecules
What is the dew point?
the temperature at which condensation forms from saturated air
What is weather?
