The continuous cycling of water from Earth's surface to the atmosphere and back again.
What is the water cycle?
100
This is made up of mostly nitrogen and oxygen
What is the atmosphere of Earth?
100
how hot or cold something is
What is temperature?
100
The reason Earth's water has lasted millions of years.
What is the water cycle?
100
Liquid that falls from the atmosphere to Earth
What is precipitation?
200
The state of the atmosphere at a certain place and time.
What is weather?
200
One of the gases that absorbs Earth's heat to keep the planet warm.
What is greenhouse gas?
200
The force of the weight of the air pressing down on you
What is air pressure?
200
Change in water from a gas to a liquid

200
Name the five types of precipitation
Rain, Snow, Sleet, Freezing Rain, Hailstones
300
the amount of water vapor in the air
What is humidity?
300
The layer of gases surrounding Earth
What is the atmosphere?
300
The movement of air from areas of high pressure to areas of low pressure.
What is wind?
300
How water enters the Earth's atmosphere.
What is evaporation?
300
Water that does not sink into the soil or fall into the ocean, rivers and lakes.
What is runoff?
400

What are the three factors that can affect climate of an area?
Latitude, elevation and nearness to large bodies of water.
500
The boundary where two different air masses meet.
What is a front?
500
Holds in heat; contains oxygen and carbon dioxide; protects Earth from some harmful solar radiation; has water vapor, which is necessary for recycling Earth's water.
What are some ways the atmosphere makes life on Earth possible?
500
How does temperature determine air pressure?
Warming air that rises causes lower air pressure; cooling air that sinks causes higher air pressure.
500
