Elements of Weather
The continuous movement of water between the atmosphere, the land, the oceans, and living things.
What is the water cycle?
An instrument that measures relative humidity.
What is a psychrometer?
A collection of small water droplets or ice crystals that are suspended in the air.
What is a cloud?
When a cloud can't get over a mountain.
What is orographic lifting?
A large volume of air in which temperature and mistake content are nearly the same throughout.
What is air mass?
The condition of Earth's atmosphere at a certain time, and place.
What is weather?
The temperature at which more condensation than evaporation occurs.
What is a dew point?
The temperature at which the rate of condensation equals the rate of evaporation.
What is dew point?
Water vapor that condenses very near Earth's surface.
What is fog?
A boundary that forms between air masses.
What is a front?
An instrument that measures and displays temperature.
What is a thermometer?
Any form of water that falls to Earth's surface from the clouds.
What is precipitation?
The change of state from a liquid to a gas that usually occurs at the surface of a liquid.
What is evaporation?
Ground fog that forms in low-lying areas on clear, calm nights.
What is radiation fog?
When air sinks slowly down.
What is a high-pressure system?
The amount of water in the air.
What is humidity?
An instrument used to measure wind speed.
What is a anemometer?
The surface on which water droplets can dense.
What is a cloud condensation nuclei?
Fog that forms over most seas.
What is sea fog?
When air rises and so has a lower air pressure than areas around it.
What is a low-pressure system?
The amount of water vapor in the air, compared to the amount of water vapor needed to reach saturation.
What is relative humidity?
A measure of transparency the atmosphere.
What is visibility?
Warm air mass over cold air mass.
What is frontal lifting?
Appears as steam directly above bodies of water.
What is steam fog?
