Why are scientists concerned with ozone depletion in the upper atmosphere?

• because it causes greater levels of ground-level ozone

• because it allows ultraviolet radiation to reach Earth's surface

• because it increases the amount of smog in highly populated cities

• because it decreases global temperatures by decreasing incoming solar radiation

How does the arrangement of the air molecules found in the troposphere compare to the arrangement of those found in the thermosphere?

• The air molecules are closer together in the troposphere and are farther apart in the thermosphere.

• The air molecules are farther apart in the troposphere and are closer together in the thermosphere.

• The number of air molecules is the same in the troposphere as in the thermosphere.

• There are fewer air molecules is the troposphere than in the thermosphere.
