Atmosphere
Layers of the atmosphere
air pressure
the wind
water cycle
100
all the air that surrounds Earth and supports life on Earth
What is the atmosphere?
100
list all of the layers in order, starting with earth.
What is :: EARTH -> Troposphere->Stratosphere->Mesosphere->Thermosphere->Exosphere
100
the force of air molecules pushing down on us
What is air pressure?
100
the movement of air across the ground, due to a PRESSURE GRADIENT
What is wind?
100
the movement of water from the ground, to the sky, and back again
What is the water cycle?
200
The combination of nitrogen, oxygen, carbon dioxide, argon, and water vapor in the air
What is the mixture of gases?
200
All weather occurs in this layer
What is the troposphere?
200
The force that pulls air molecules DOWN towards Earth
What is gravity?
200
the transfer of heat by the movement of air or gas...wind carries heat this way.
What is convection?
200
When water falls from the sky as rain, sleet, snow, or hail
What is precipitation?
300
Makes up 78% of our atmosphere
What is nitrogen?
300
This layer is the hottest and has high temperatures
What is the thermosphere?
300
When air molecules are held tightly by gravity near the surface, the pressure will...(increase or decrease)
What is increase?
300
hot air ________ and cold air _________
What is rises and sinks?
300
When water molecules change from a liquid (on the ground) to a gas (in the air)
What is evaporation / transpiration?
400
Makes up 21% of our atmosphere
What is oxygen?
400
Jets and air planes
What is the stratosphere?
400
When air molecules spread out, the air pressure will...(increase / decrease)
What is decrease?
400
When the temperature is hot, the air heats up, and air pressure __________
What is decreases?
400
when water molecules come together and form clouds
What is condensation?
500
makes up 1% of our atmosphere
What is carbon dioxide, argon, and water vapor?
500
Meteros burn up in this layer
What is the mesosphere?
500
As your elevation increases, your air pressure goes from _________ to _________
What is "high air pressure" to "low air pressure"
500
When the temperature is cold, the air pressure_____________________(think about the direction in which air moves)
What is increases?
500
When water is collected in rivers, lakes, and streams
What is run-off?
