Ozone Depletion Potential (ODP) UPDATED
ACTUAL Exam Questions and CORRECT
Answers
Recall from our Ozone module that ozone is a molecule found in our ----. It ---- and ---- harmful
UV rays from the sun. - CORRECT ANSWER - atmosphere, absorbs, reflects
When released into the atmosphere, certain refrigerants are especially potent at destroying ozone.
This is because the refrigerants contain ----. - CORRECT ANSWER - chlorine
CFCs and HCFCs are the most harmful because they contain chlorine. These refrigerants are also
relatively stable, meaning they don't get ---- easily by rain or sunlight. This makes it more likely
that they will reach the stratosphere, where the ---- layer is. - CORRECT ANSWER -
destroyed, ozone
Refrigerant chemicals have a lifespan of ---- - this is how long they will stay in the ----,
destroying ozone until they are broken down ----. - CORRECT ANSWER - 70-100 years,
atmosphere, naturally
We can characterize the potential of a refrigerant to destroy ozone as its ----. The ODP number
we assign to a refrigerant tells us how ---- that refrigerant is to ozone in the atmosphere. -
CORRECT ANSWER - Ozone Depletion Potential (ODP), harmful
---- are the most destructive to the ozone layer so its ODP is the highest. The next most
destructive are ----. - CORRECT ANSWER - CFCs, HCFCs
You can think of ODP as similar to the ---- scale, which describes the ---- of earthquakes. On the
Richter scale, the ---- the number is, the larger the magnitude of the ----. - CORRECT
ANSWER - Richter, severity, higher, earthquake
