Layers of the Atmosphere
Developed by Jack Fearing
Lincoln Junior High School
Hibbing, Minnesota
Objective:
By making a graph, you will discover how the atmosphere can be divided into
layers based on temperature changes at different heights.
Background:
The atmosphere can be divided into four layers based on temperature variations.
The layer closest to Earth is called the troposphere. Above this layer is the
stratosphere, followed by the mesosphere, then the thermosphere. The upper
boundaries between these layers are known as the tropopause, the stratopause,
and the mesopause, respectively.
Temperature variations in the four layers are due to the way solar energy is
absorbed by different gases as it moves downward through the atmosphere.
Earth's surface (the ground) is the primary absorber of solar energy. Some of this
energy is reradiated back away from Earth as heat, which warms the overlying
troposphere. The global average temperature in the troposphere rapidly decreases
with altitude until the tropopause, the boundary between the troposphere and the
stratosphere.
The temperature begins to increase with altitude in the stratosphere. This
warming is caused by a form of oxygen gas called ozone (O3), which absorbs UV
radiation from the sun. Ozone protects us from most of the sun's UV radiation,
which can cause cancer, genetic mutations, and sunburn. Scientists are concerned
that human activity is contributing to a decrease in stratospheric ozone. Nitric
oxide, which is in the exhaust of high-flying jets and chlorofluorocarbons (CFCs),
which are used as refrigerants, may contribute to ozone depletion.
At the stratopause, the temperature stops increasing with altitude. The gases in
the overlying mesosphere do not absorb solar radiation well so the temperature in
the mesosphere decreases with altitude. At the mesopause, the temperature begins
to increase with altitude and this trend continues in the thermosphere. Because
the atmosphere in the thermosphere has such little density, a thermometer cannot
measure the temperature accurately here so special instruments are needed.
6
Procedure:
1.
Table 1 contains average temperature readings at various altitudes in Earth's atmosphere. Plot this data on
the graph included on the next page and connect adjacent points with solid lines. Be careful to plot
negative temperatures correctly. This profile provides a general picture of temperature conditions in the
atmosphere; at any given time and place, however, the actual temperature may deviate from these average
values, particularly in the lower atmosphere.

Lab 1: Can Crusher
The kinetic energy of particles affects the amount of pressure those particles can exert on their
surroundings and the amount of pressure their surroundings can exert on them. This
phenomenon is most noticeable when the particles are in a gaseous state. Why do you think this
is most noticeable in gases?
For example, if a balloon is left in a sunny location, the particles of gas inside the balloon will
experience an increase in kinetic energy as they get warmer and move more quickly. This will
cause the balloon to expand, thus increasing the pressure inside the balloon. The balloon swells
because the pressure inside of it is greater than the pressure outside of it. The gas has become
less dense than it originally was because its particles have become less “concentrated” (spread
out in a larger space).
On the other hand, if this same balloon is placed in a freezer, the particles of gas inside the
balloon will experience a decrease in kinetic energy as they get colder and move more slowly. In
this situation, the balloon shrinks because the pressure inside of it is less than the pressure
outside of it. The gas has become more dense than it originally was because its particles have
become more concentrated.
Objective:
1. Explain what happens to the kinetic energy of particles as they change from one state
to another.

Lab 2: Greenhouse Effect Model
Introduction:
The “greenhouse effect” is Earth’s heating process in which gases in the atmosphere trap thermal
energy. These gases include water vapor, carbon dioxide, nitrous oxide, and methane. These
gases, also known as “greenhouse gases,” are sometimes the end result of burning fossil fuels
such as gas, oil, and coal. Most people consider the greenhouse effect as beneficial (good) for
our existence on Earth. Scientists estimate that Earth’s average temperature would be about 0 °F
instead of its current 57 °F if we had no greenhouse effect. This is a huge difference! Without
the greenhouse effect, we wouldn’t be able to grow food for survival. The problem isn’t that we
have a greenhouse effect; the problem is that human activities might be leading to an increase in
the greenhouse effect. What could this cause to happen? Why might this be a problem? In this
activity you will have the opportunity to make a model of Earth in a jar and see what a dramatic
effect the “greenhouse effect” has on our planet.

1. You should be able to explain the greenhouse effect and what could happen if it gets out of
balance.
2. You should be able to read and interpret a graph and draw conclusions from the graph.
3. You should be able to come up with alternative methods of conserving energy to slow down
global warming.

Going Green
In order to slow down the greenhouse effect, we all must cut down on the amount of
energy that we use. Factories and transportation produce most greenhouse gases. Most
of the products that we use in our homes require the use of fossil fuels to produce that
item in a factory. We must learn to conserve energy and resources in order to slow down
the greenhouse effect or we will have global warming and other problems.
In the chart below name some activities and a way that you can conserve energy for
that activity. An example has been provided to get you started.
Alternate activity to help conserve
energy and why this will help cut down
on greenhouse gas emissions.
Activity
Example: Many people drive their cars to
work alone.
Ride a public transportation system such as
a train or bus. Carpool with other people
who work near where you work. This will
reduce the amount of gas burned and the
amount of carbon dioxide emitted into the
air.
