Weather Facts
100
The condition of the atmosphere at a certain time and place.
What is weather?
100
A collection of small water droplets that are suspended in the air.
What is a cloud?
100
The continuous movement of water through the atmosphere, land, and water of the Earth.
What is the water cycle?
100
The weather over a long period of time.
What is climate?
100
This instrument measures wind direction.
What is a wind vane or wind sock?
200
How hot or cold something is.
What is temperature?
200
The temperature at which the rate of condensation equals evaporation.
What is a dew point?
200
A large volume of air in which the temperature and moisture content are the same throughout.
What is an air mass?
200
Angular distances in North and South degrees from the equator.
What is latitude?
200
This instrument measures wind speed.
What is an anemometer?
300
The amount of water vapor in the air.
What is humidity?
300
Water vapor that condenses close to the surface.
What is fog?
300
A boundary between two air masses caused by density differences.
What is a front?
300
This influences wind patterns and energy transfer in an area or this can be described as the surface features of an area.
What is topography?
300
This front is formed when a warm air mass follows a retreating cold air mass.
What is a warm front?
400
The force of air molecules pushing on an area.
What is air pressure?
400
A warm air mass rises over a cold air mass or when a cold air mass slides underneath a warm air mass.
What is frontal lifting?
400
The unequal heating of Earth's surface causes pressure differences which causes air to move.
What is wind?
400
The height of an area above sea level.
What is elevation?
400
This region has less than 25 centimeters of precipitation fall every year.
What is the desert?
500
The amount of water vapor in the air compared to the amount of water vapor needed for the air to reach saturation?
What is relative humidity?
500
When an obstacle such as a mountain forces a clod or warm air mass upward.
What is orographic lifting?
500
Air in this pressure system sinks slowly and then spreads out.
What is a high pressure system?
500
Currents that are on the surface of the ocean and are caused be winds.
What is a surface current?
500
This region has more than 250 centimeters of precipitation fall per year.
What is a tropical rainforest?
