Basics
This is the layer of gases surrounding Earth
Atmosphere
This gas makes up about 78% of the atmosphere
Nitrogen
This is the lowest layer where we live
Troposphere
In this layer, temperature gets colder as you go up
Tropo
Weather mainly occurs in this layer
Troposphere
The atmosphere is often compared to this item
Blanket
This gas makes up about 21% of the atmosphere
Oxygen
This layer contains the ozone layer
Stratosphere
In this layer, temperature gets warmer as you go up
Strato
Rain, snow, and wind are examples of this
Weather
The atmosphere provides this gas for breathing
Oxygen
This gas is only about 0.04% of the atmosphere
CO^2
This layer is where meteors burn up
Mesosphere
Air pressure does this as you go higher
Decreases
These gases trap heat in the atmosphere
GreenHouse
The atmosphere protects us from this harmful energy
UV Rays
These are small amounts of other gases in the atmosphere
Trace Gases
This layer is where auroras occur
Thermosphere
Air pressure is highest at this location
What is Earth’s surface?
This human activity is increasing greenhouse gases
What is pollution / burning fossil fuels?
Without the atmosphere, this would NOT be possible on Earth
LIfe
This is something that uses oxygen from the air
Humans / Animals
This is the outermost layer that fades into space
Exosphere
It is harder to breathe at high altitudes because of this
Low Air Pressure
One way to protect the atmosphere
What is using renewable energy / reducing pollution?
