meteorology

Two air masses meet

• fronts

• air pressure

• atmosphere

• humidity

What instrument is use to measure air pressure

• anemometer

• thermometer

• barometer

• Hygrometer

forms when a mass of cold air meets and replaces a mass of warm air

• warm front

• occluded front

• cold front

• stationary front

Which is NOT one of the three factors that cause the weight of air

• change in altitude

• change in pressure

• change in composition

• change in temperature

forms when a mass of warm air overtakes a cold air mass and moves over it.

• warm front

• occluded front

• cold front

• stationary ftont

warm air mass meets a cold air mass and no movement occurs

• warm fronts

• occluded fronts

• cold fronts

• stationary fronts

the quantity of water vapor in the air

• humidifier

• humidity

• low humidity

• high humidity

The amount of water vapor that air holds divided by all the water vapor it can hold

• absolute humidity

• high humidity

• relatively humidity

• low humidity

evaporation can occur grom bodies of water and other sources

• high humidity

• relative humidity

• absolute humidity

• low humidity

the amount of water vapor that the air is actually holding

• high humidity

• absolute humidity

• low humidity

• relative humidity
