What gas makes up most of the atmosphere?

Nitrogen

100

75 percent of the atmosphere is located in this layer.

Troposphere

100

movement of air from areas of high pressure to areas of low pressure

winds

100

Which type of Radiation are the colors that we see?

Visible Light

100

_____ air rises, while _____ air falls.

Warm, Cold

200

What percent of Earth's atmosphere is made up of oxygen?

21%

200

This is the outermost layer of the atmosphere.

Exosphere

200

Give two characteristics of Local Winds

-blow over short distances
-create unequal heating
-occur in a small area
-include land and sea breezes

200

This form of heating happens when the atmosphere touches the Earth.

Conduction

200

Rising warm air creates an area of ____ pressure.

Low pressure

300

What is Earth's atmosphere important?

Give TWO reasons

-Traps heat from the Sun

-Protects us from radiation
-Protects us from meteors
-Makes Earth livable

300

Which layer contains Earth's ozone layer?

Stratosphere

300

Give two characteristics of Global Winds.

-blow steadily over long distances
-created by unequal heating
-occur over large areas
-such as global wind belts

300

_______________ currents are formed when warm air from Earth's surface rises and cool air falls.

Convection

300

What kind of weather would we expect in areas of low pressure?

Clouds, rainfall/precipitation

400

How is air pressure measured?

With a Barometer

400

This layer is where meteors burn up.

Mesosphere

400
The curved path that winds follow because of the spinning of the Earth is called

Coriolis Effect

400

This type of radiation is felt as heat, but is not seen.

Infrared Radiation

400

What 3 events do scientists believe led to our current atmosphere?

1. Water condensed into the ocean

2. CO2 dissolved into the ocean

3. Photosynthesis produced oxygen

500

How many layers are there in the atmosphere?

Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere

500

This layer contains the Aurora Borealis

Thermosphere

500

What are the 3 major wind bands and where are they?

 Draw a diagram.

Polar Cell (at the pole)

Ferrel Cell (between pole and equator)

Hadley Cell (over equator)

500

Radiation causes the _______________ __________ which warms the Earth.

Greenhouse Effect

500

How does the tilt of the Earth affect the seasons?

Tilted toward the Sun = Summer

Away from the Sun = Winter

Neither to or away = Fall/Spring
