Content Objective
I can apply knowledge of the differences in air pressure and air temperature at different elevations by completing a Layers of the Atmosphere activity with my cooperative learning group.

E.EF.07.12 Compare and contrast the composition of the atmosphere at different elevations.

Language Objective
I can write to compare the differences in air pressure and air temperature at different elevations by completing the following sentence frames.

STUDY for the QUIZ -composition and layers of the Earth’s atmosphere (Monday)

1.The Earth’s atmosphere is divided into layers based on changes in ___________________.

2.These changes occur because at certain altitudes __________________________________________.

3.We live in the layer closest to the Earth called the __________.

4.In our atmosphere, as altitude increases, temperature ____________.  This is because _______________.

5.The layer of our atmosphere that protects us from dangerous ultraviolet radiation is called the ________.

6.In our atmosphere, as altitude increases, air pressure ______________  This is because__________________.

1.The Earth’s atmosphere is divided into layers based on changes in temperature.

2.These changes occur because at certain altitudes the different gases absorb the suns energy and get hot.

3.We live in the layer closest to the Earth called the troposphere.

4.In our atmosphere, as altitude increases, temperature decreases, then increases, then decreases, then increases. This is because different layers of gases at different altitudes absorb the suns energy and get warmer.

5.The layer of our atmosphere that protects us from dangerous ultraviolet radiation is called the ozone.

6.In our atmosphere, as altitude increases, air pressure decreases.  This is because the further you get from the Earth’s surface, the less air molecules that will be pushing down on you.
