Ozone_and_Atmosphere

What technological tool allows scientists to monitor ozone levels around the Earth?

Satellites

How man miles above the Earths's surface is the ozone layer located?

10-40 Kilometers 7-28 Miles

In order for CFC's to be bombarded by UV, the CFC's must first travel to what region of the atmosphere?

CFC's must get up in and above the ozone layer to get exposed to UV - for splitting

What is the difference between "good" and "bad" ozone?

Good ozone is found in the stratosphere and good ozone is decreasing in our protective ozone layer. Bad ozone is found in the trospheric, bad ozone increasing in the air we breathe.

What is the source of CFC's in our atmosphere?

Human production of chemicals

With respect to ozone depletion, what makes this region different from other places on Earth?

Over the polar region there are PSC.

While CFC's are near the Earth's surface they are protected from UV by what molecule?

Ozone O3

Oer what region of the earth has the greatest loss of ozone been detected?

The polar regions

CFC's are generally stable molecules. What type of energy has the ability to break these molecules?

UV

Energy is required to split an ordinary molecule of oxygen. What is the source of this energy?

UV; the sun

Is ozone considered to be a stable or unstable molecule?

Unstable, it splits easy

Scientists are in widespread agreement that ozone levels are decreasing. What major question
