Elements of weather
Device for measuring temperature.
What is a thermometer?
A cloud that forms near earth's surface.
What is fog?
The boundary between two air masses.
What is a front?
What is the water cycle?
The short term state of the atmosphere.
What is weather?
The amount of water vapor in the air.
What is humidity?
The process in which cold air slides under warmer air and forces it to rise.
What is frontal lifting?
A large body of air in which temperature and moisture are nearly the same throughout.
What is an air mass?
The process in which water is turned into water vapor with heat.
What is evaporation?
How far we can see, often measured with the distance between two landmarks.
What is visibillity?
Tool used to measure air pressure.
What is a barometer?
A collection of small water droplets or ice crystals suspended in air.
What is a cloud?
Long distance winds that travel for many kilometers.
What is a jet stream?
Any form of water that falls from clouds.
What is precipitation?
Tool used for measuring wind speed.
What is an anemometer?
How hard air molecules push on an object.
What is air pressure?
The process in which an obstacle forces air up which then cools.
What is orographic lifting?
The pressure system in which air sinks and cools.
What is a high pressure system?
The process of water turning to water vapor through plants.
What is transpiration?
The temperature point in which more condensation than evaporation occurs.
What is the dew point?
Air that moves parallel to the ground.
What is wind?
Tiny particles that water condenses on in the air.
What are cloud condensation nuclei?
The front in which warm air rises above colder air.
What is a warm front?
The process of water vapor turning back to water, typically forming clouds.
What is condensation?
The amount of water vapor in the air compared to the amount needed to reach saturation.
What is relative humidity?
