Properties of Air
Layers
Layers 2.0
The Earth's Atmosphere
Air Stuff
100
An envelope of gases that surround the Earth
What is the atmosphere?
100
Clouds, greenhouse gases, and the weather
What is found in the troposphere?
100
Layer closest to the Earth
What is the troposphere?
100
Nitrogen
What is the most abundant gas in the Earth's atmosphere?
100
Means middle
What is 'meso'?
200
Molecules move faster and it expands
What happens when air is heated?
200
In the stratosphere
Where is the ozone layer?
200
Layer farthest from the Earth
What is the Exosphere?
200
Oxygen
What is the 2nd most abundant gas in the Earth's atmosphere? OR What gas do we need to in order to survive?
200
Means outer
What is 'exo'?
300
It decreases
What happens to air pressure as you go up in the atmosphere? OR What happens to the density as you go up in the atmosphere?
300
It is where meteoroids burn up & protect the Earth
What is important about the mesosphere?
300
It gets colder when you go up in these 2 layers
What happens to the temperature in the troposphere and mesosphere?
300
A meteoroid burning up in the mesosphere
What causes a shooting star?
300
Means heat
What is 'thermo'?
400
Air has mass and air can exert a force
What are 2 properties of air?
400
In between the troposphere and stratosphere
Where is the jet stream?
400
Because they are the closest to the sun
Why are the thermosphere and exosphere the warmest of the atmospheric layers?
400
Troposphere, Stratosphere, Mesosphere, Thermosphere, Exosphere
What is the order of the atmosphere layers from the surface to outer space? OR What are the layers of the atmosphere?
400
In the thermosphere
Where are the northern lights located? OR Where are the International Space Station, Space Shuttle, Hubble Telescope and many satellites located?
500
The amount of mass in a given volume
What is density?
500
Because the ozone layer absorbs the sun's ultraviolet rays
Why does it heat up in the stratosphere?
500
Based upon changes in temperatures
How are the layers of the atmosphere classified / separated?
500
Because atmospheric gases become thinner the higher you go up.
Why is it harder to breathe at higher altitudes?
500
A form of oxygen with 3 atoms of oxygen in each molecule
What is ozone?
