1. Besides providing air to breathe, in what other 3 ways does the atmosphere support life?
a. __________________________________________________________________________
b. __________________________________________________________________________

__________________________________________________________________________
2. What are the 5 gases that you find in the atmosphere? ________________________________
___________________________________________________________________________________
3. What are 3 examples of particles that can be found floating in the atmosphere? _________

6. Name the 5 layers of the atmosphere:
a. __________________________________________________________________________
b. __________________________________________________________________________
c.
__________________________________________________________________________
d. __________________________________________________________________________
e.

7. The troposphere is the _____________________________ layer of the atmosphere. It extends
to
km above sea level. Humans live in the troposphere and nearly all
occurs in this layer. Air pressure
and temperatures get
as
you climb higher in this layer.
8. The stratosphere extends from the top of the troposphere to
km. It contains
the infamous ______________________________ which absorbs ________________ radiation
from the sun. Temperatures
fly in the lower stratosphere and the
as you go higher. Commercial
flows near the border.
9. The mesosphere extends to a height of about
km.
burn
up in the mesosphere. As you go higher in the mesosphere, the temperature becomes
_________________________.
10. High energy
and
radiation are absorbed in the
thermosphere. The thermosphere is more like
than a part of the
atmosphere. Many
actually orbit Earth within the
thermosphere. The aurora, or
lights occur in the
thermosphere.
11. Some experts consider the thermosphere to be the uppermost layer, but others think the
is the final frontier. Air in the exosphere is constantly,
though very gradually,
out the atmosphere into space.
12. The ionosphere is not a distinct layer but is a series of regions in parts of the
