This is a brief quiz about the lecture on Earth's stratospheric ozone layer. The quiz is based on the
original ozone presentation and also the updated lecture on new information. What chemical element has led to declines in Earth’s ozone layer?

2/3
This is the best answer.
Question 2
0.4 / 0.4 pts
Very cold winter temperatures make ozone brittle. In other words, the bonds between the three oxygens become
easier to destroy upon interaction with the chlorine.
Very cold winter temperatures make it hard for ozone molecules to break apart.
Correct!
Very cold winter temperatures in the stratosphere produce polar stratospheric clouds (PSC), and these PSCs help
breakdown chlorofluorocarbons.
Very cold winter temperatures make snow.
This is the best answer.
Question 3
0 / 0.4 pts
Correct Answer
fly ash from coal
pesticides
aerosols
You Answered
refrigerants
Fly ash from coal is the most recent discovery of an ozone-destroying agents. Also, the answer that you
selected is actually not necessarily an ozone-destroying agent. There are a few pesticides linked to
ozone destruction, but not pesticides in general. There are a few refrigerants linked to ozone
destruction, but not all. And there are LOTS of aerosols that are not linked to ozone destruction. Thus,
the answer you picked is definitely not the best one.
Question 4
0.4 / 0.4 pts
The greatest amount of ozone destruction in the stratosphere is associated with extremely cold winter
temperatures. Why are extremely cold winter temperatures important?
What is an example of a relatively new discovery of an agent that destroys stratospheric ozone? Select
the best answer
How does the ozone layer in the stratosphere help reduce ultraviolet radiation?

3/3
Ozone is like a mirror, bouncing the ultraviolet radiation back to space.
Ozone reduces UV radiation in the same way that a car’s sunscreen works. It just blocks all light.
Correct!
The ozone molecule (O
) has properties that help it absorb ultraviolet radiation, and this absorption is the reason
why temperatures in the stratosphere go up closer to the sun. Ozone does not reduce ultraviolet radiation. This is just a rumor made up by scientists to get government grants.
This is the best answer.
