Atmosphere Study Guide
Answer Key
Atmosphere is the envelope of gases that surround the planet
Weather is the condition of the Earth’s atmosphere at a particular time and place
What is the instruments that
measures air pressure?
Barometer
What is Altitude?
distance above sea level
What is the most abundant gas in the
atmosphere?
Nitrogen 78%
Which gas is the 2nd most abundant in
the Earth’s atmosphere?
Oxygen 21%
What percent of our atmosphere is
made up of nitrogen and oxygen?
78% + 21% =
99%
What percent of our atmosphere is
made up of gases other than nitrogen?
100 – 78 =
22%
What percent of our atmosphere is
made up of gases other than oxygen?
100 – 21 =
79%
What percent of our atmosphere is
made up of gases other than nitrogen
and oxygen?
78 + 21 = 99
100 – 99=
1%
What are the two most abundant
gases, and what percentage are they
in the atmosphere?
Nitrogen 78%
Oxygen 21%
Scientists use this as a way of dividing
the different layers of the atmosphere
Changes in the temperature
How is carbon dioxide produced?
Breathing
Burning Fossil Fuels Cars
Factories
The function or purpose of the ozone
layer is:
Protects earth from UV Rays

What is the relationship between air
pressure and density?
Air Pressure Increases: Density Increase,
Air pressure decreases: Density Decreases
What happens to density when you
change altitude?
High (increase) Altitude:
LOW DENSITY (Density decreases)
What happens to density when you
change altitude?
Low (Decrease) Altitude:
HIGH DENSITY (Density increases)
What happens to pressure when you
change altitude?
High (increase) Altitude:
LOW AIR PRESSURE (air pressure decreases)
What happens to pressure when you
change altitude?
Low (decrease) Altitude:
INCREASE AIR PRESSURE (GETS HIGHER)
What makes conditions right for life
on earth?
THE ATMOSPHERE
We couldn’t live without it
What are things we can do to help
improve air quality
Carpool
ride bikes
Walk
public transportation
filters on factories
