Earth’s Atmosphere
Why is it so important to life on
earth?
S6E4 Students will understand
how the distribution of land and
ocean affects climate and weather
Today at a Glance 2-22-16 S6e5d Minerals, Rocks,
Fossils, & S6e4 SW understand the land and ocean’s
affects on climate and weather
Activity 1: We Do: Bell work
Determine if the statement is true or false. Cite
evidence.
1. Moving water can be used to produce electricity.
2. Water wheels were once used to power cars.
3. Hydroelectric dams can cause many ecological
problems.
4. Hydroelectric energy is non-renewable.
Activity 2 mini lesson I DO/You DO
Review for test.
Activity 3: I Do/ You Do: Earth’s atmosphere notes
Earth’s atmosphere is made
up of 5 different layers…

THE FIVE LAYERS
OF THE EARTH’S
ATMOSPHERE
FROM THE EARTH
OUT!
Why is the atmosphere
divided into 5 different
layers?  Any guesses?



The atmosphere is divided into
five different layers because the
atmosphere is not uniform, its
properties change with altitude.
Two properties change with
altitude, the AIR PRESSURE
and the AIR TEMPERATURE
Lets look at each layer
individually.
The first layer of the atmosphere
is the…
TROPOSPHERE






The troposphere is the layer of the atmosphere nearest
to earth.
The troposphere goes from 0km to 16km.
All weather happens in the troposphere.
More than half the air in the total atmosphere is in this
layer.
The temperature drops as the altitude increases.
Harmful ozone is found here…IT CREATES SMOG!
What is OZONE?

A gaseous layer in the upper
atmosphere that protects the earth
from harmful ultraviolet radiation. At
lower levels, ozone becomes a major
pollutant.
What is SMOG?

Pollution formed by the
interaction of pollutants and
sunlight (photochemical
smog), usually restricting
visibility, and occasionally
hazardous to health.





The second layer of the
atmosphere is the…
The stratosphere goes from
STRATOSPHERE
16km to 50 km.
The temperature goes up
with altitude.
Most jets fly in this layer.
The protective ozone is at
the top of the atmosphere (It
protects us from the
ultraviolet radiation of the
sun.)
Rivers of air, called Jet
Streams, can be found at
the base of this layer.
The third layer of the atmosphere
is the…
MESOSPHERE





The Mesosphere goes from
50km to 90km.
In the mesosphere, the
temperature drops with
altitude.
The mesosphere is the
coldest layer of the
atmosphere.
Meteors burn up in this layer.
Radio waves are reflected
back to earth in the
mesosphere.
The fourth layer of the
atmosphere is the…
THERMOSPHERE





The thermosphere goes from 90km to 300km.
In the thermosphere the temperature goes up with
altitude.
The thermosphere is the hottest layer of the atmosphere.
Curtains of light called auroras occur in this layer.
The Ionosphere is found in the thermosphere. This is
the component of the thermosphere that makes the
auroras.
The last layer of the atmosphere
is the…
EXOSPHERE



The exosphere is the
outermost layer of the
atmosphere.
The temperature in
the exosphere goes
up with altitude.
Satellites orbit earth
in the exosphere.
It is important to understand the different
characteristics of the earth’s atmosphere. As
you go through the following slides, challenge
your partner to see who can name the correct
layer in which each characteristic can be
found.
GOOD LUCK!
Today at a Glance 3-2-16
S6E4 Students will understand how the distribution of
land and ocean affects climate and weather
Activity 1: Bell Work We Do
1. Why do you think rain and clouds occur
mostly in troposphere?
2. Where is air pressure greater?
3. Define the term ionosphere.
Activity 2: you will work in groups of 3 to
create a skit about how the depletion of the
ozone layer might affect different organisms.
Wait for directions. You will have 15 min only

Activity 2 continue You Do
1. Your organism must be found on earth
2. Your organism must discuss the changes
they are experiencing and their concerns for
the future.
3. You will present the skit to the class
