100

Device for measuring temperature.

What is a thermometer?

100

A cloud that forms near earth's surface.

What is fog?

100

The boundary between two air masses.

What is a front?

100
The continuous movement of water.

What is the water cycle?

100

The short term state of the atmosphere.

What is weather?

200

The amount of water vapor in the air.

What is humidity?

200

The process in which cold air slides under warmer air and forces it to rise.

What is frontal lifting?

200

A large body of air in which temperature and moisture are nearly the same throughout.

What is an air mass?

200

The process in which water is turned into water vapor with heat.

What is evaporation?

200

How far we can see, often measured with the distance between two landmarks.

What is visibillity?

300

Tool used to measure air pressure.

What is a barometer?

300

A collection of small water droplets or ice crystals suspended in air.

What is a cloud?

300

Long distance winds that travel for many kilometers.

What is a jet stream?

300

Any form of water that falls from clouds.

What is precipitation?

300

Tool used for measuring wind speed.

What is an anemometer?

400

How hard air molecules push on an object.

What is air pressure?

400

The process in which an obstacle forces air up which then cools.

What is orographic lifting?

400

The pressure system in which air sinks and cools.

What is a high pressure system?

400

The process of water turning to water vapor through plants.

What is transpiration?

400

The temperature point in which more condensation than evaporation occurs.

What is the dew point?

500

Air that moves parallel to the ground. 

What is wind?

500

Tiny particles that water condenses on in the air.

What are cloud condensation nuclei?

500

The front in which warm air rises above colder air.

What is a warm front?

500

The process of water vapor turning back to water, typically forming clouds.

What is condensation?

500

The amount of water vapor in the air compared to the amount needed to reach saturation.

What is relative humidity?
