True: Gas is a fluid because it doesn't have a specific shape.

Which layer of the atmosphere do we live in?
Troposphere
100
Where is the air density the highest?
In the troposphere or closer to the surface of the Earth.
100
Which gases cause the greenhouse effect?
Carbon Dioxide (CO2), Water Vapor (H2O), Methane (CH4)
100
The amount of mass in a given area (mass/volume)
Density
200
The most abundant gas in the atmosphere making up 78% of the atmosphere
Nitrogen (N2)
200
This is the layer where weather happens (i.e. clouds, storms, etc.)
Troposphere
200
Why does the temperature in the troposphere and the mesosphere decline as the altitude increases
Possible answer: air density decreases so heat doesn't transfer as much; "it's like it has less coats" as you go up
200
The greenhouse effect is a natural process.
True or False?

What is the second most abundant gas in the atmosphere which makes up 21%?
Oxygen (O2)
300
This layer contains the protective ozone layer
Stratosphere
300
Why does temperature increase with altitude in the stratosphere?
The ozone layer absorbs the sun's radiation and warms the stratosphere.
300
What does the greenhouse effect do for Earth?
Maintains a warm temperature suitable for life
300
The distance above sea level (how high above Earth each layer is)
Altitude
400
What do the gases in the atmosphere do for the Earth? At least two examples
Possible answers: Insulates the planet (keeps it at the right temperature); living things use it to breathe; It protects us from harmful radiation from the sun.
400
This layer helps to burn up meteors that enter our atmosphere
Mesosphere
400
Where will there be more air pressure? at the beach or at the top of a tall mountain?
At the beach
400
What can happen if the gases that cause the greenhouse effect get too high?
The planet will get too warm
400
Also known as the northern lights
Aurora Borealis
500
Which gas is composed of three oxygen molecules (O3) and protects the Earth from harmful Ultraviolet (UV) rays from the sun
Ozone (O3)
500
The outermost layer in the atmosphere where many satellites orbit Earth
Exosphere
500
Which layers has the highest temperature?
Thermosphere and Exopshere
500
What are some effects of global warming? (At least 2)
Possible answers: Polar ice caps melt; sea level rises; certain species will die; the planet will get warmer; more severe weather
