Where most water evaporates from.
What is the ocean?
Instrument that measures humidity
What is a hygrometer?
The factor that determines whether precipitation will be a solid (snow) or a liquid (rain)
What is air temperature?
The weather created by these conditions: low humidity, high pressure, cirrus clouds
What is a dry, sunny day?
Instrument that measures air temperature
What is a thermometer?
Precipitation that forms when the air temperature is above freezing (0*C or 32*F)
What is rain or hail?
The weather created by these conditions: high humidity, low pressure, stratus clouds, 15*C (59*F)
What is light rain?
Thin, feathery clouds that appear high in the sky; they are a sign of fair weather
What are cirrus clouds?
Instrument that shows wind direction
What is a wind vane?
Precipitation that forms when the air temperature is below freezing (0*C or 32*F)
What is snow or sleet?
The weather created by these conditions: low humidity, high pressure, cumulus clouds
What is a dry, sunny day?
The process of water vapor (gas) turning into water droplets (liquid)
What is condensation?
Clouds are made from water that is in this state of matter
What is liquid?
Instrument that measures wind speed
What is an anemometer?
The precipitation that forms when raindrops pass through a layer of freezing air and turn solid
What is sleet?
The weather created by these conditions: high humidity, low pressure, stratus clouds, 0*C (15*F)
What is light snow?
The energy that powers evaporation.
What is heat from the sun?
Instrument that measures air pressure
What is a barometer?
Precipitation that forms when strong updrafts of wind carry water droplets into the atmosphere where they freeze before falling again
What is hail?
The clouds seen during severe rain or hail storms
What are cumulonimbus clouds?
