What is the water cycle?
100
These lines connect locations that have the same air pressure.
What are isobars?
100
This layer in the atmosphere protects us from UV radiation.
What is ozone?
100
This major wind system brings us our weather.
What is the prevailing westerlies?
100
This is the smallest unit of an element.
What is an atom?
200
The uneven heating of causing it to rise and fall is created by this process.
What is convection?
200
Lines that contain triangles represent this on a weather map.
What is cold front?
200
Air is mostly composed of this gas.
What is nitrogen?
200
This is the relative humidity when the wet-bulb and dry-bulb temperatures are equal.
What is 100%
200
Two or more atoms combined chemically are called this.
What is a compound?
300
This effect causes the wind to bend or change direction.
What is the Coriolis effect?
300
On a weather station model, the number that is top and left of the circle represents this.
What is present temperature?
300
The part of the air that changes from day to day.
What is water vapor?
300
As warm moist air rises, it cools and forms these.
What are clouds?
300
Atoms are free to move at high speeds with great distances between them in this state of matter.
What is a gas?
400
The sun's energy reaches Earth by this process.
What is radiation?
400
A falling barometer usually indicates this.
What is stormy, rainy, or poor weather?
400
Air pressure is greatest when it has these TWO characteristics.
What is cold and dry?
400
These tall clouds cause thunderstorms.
What are cumulonimbus clouds?
400
Gas changes to liquid during this process.
What is condensation?
500
As ice melts its volume decreases. This is an example of a change in this.
What is a phase change.
500
When lines on a weather map are close together, it usually indicates this about wind.
What is high wind speed?
500
Weather occurs in this layer of the atmosphere.
What is the troposphere?
500
This front occurs when three air masses collide and the middle one is cut off from the surface.
What is an occluded front?
500
When sulfur dioxide, created by burning fossil fuels, mixes with water in the air, it creates this type of precipitation.
What is acid rain?
