THE ATMOSPHERE
atmosphere
defination:the layer of gases that
surrounds the Earth
weather: the condition of earth’s
atmosphere at any given time or place
What gases are in our atmosphere?
Nitrogen(N2)=78%
OXYGEN(O2)=21%
TRACE GASES=1%
ARGON
CO2
NEON
METHANE
KRYPTON
HYDROGEN
WHAT ARE SOME SOURCEC OF CARBON
DIOXIDE (CO2) IN OUR ATMOSPHERE?
 BURING FOSSIL FULES RELEASE CO2
INTO THE ATMOSPHERE
 GREENHOUSE EFFECTS-CO2 AND OTHER
GASES ACT AS A BLANKET TO HOLD IN
HEAT CLOSE TO EARTH
OZONE
O3- A FORM OF OXYGEN WITH 3 ATOMS OF
OXYGEN INSTEAD OF 2
THE LAYER OF OZONE
IN THE ATMOSPHERE
ABSORB UV
RADIATION FROM
THE SUN AND HEST
THE EARTH
air pressure
 Definatin – the weight of a column of air
pushing down on an air
 More dense air has higher air pressure than less
dence air.
 Barometer – an instrument used to measure air
pressure
altitude
 Definition- the distance above sea level
 The higher the altitude the lower the air
pressure.
properties of air:
1. Mass – even though you can’t see it, air has
mass
2. Density - the density of air near earth’s
surface is greater than its density at high
altitudes
3. Pressure - air exerts a force called pressure
Notes Quiz
1. What is the most abundant gas in our
atmosphere?
2. What are some trace gases that are in
our atmosphere? (name 3)
3.What is ozone?
 Liquid oxygen
 Oxygen molecules with 3 atoms of oxygen
instead of 2
 A form of rust
6.What is air pressure?
7.In what 2 units is it measured?
8.How is air pressure affected by
density?
9.How is air pressure affected
by altitude?
10.Does air have mass? How do
you know?
