Example Questions

Example Question #1 : Ozone Formation

Where in the atmosphere does the ozone layer reside?

Possible Answers:

Mesosphere

Troposphere

Stratosphere

Thermosphere

Correct answer:

Stratosphere

Explanation:

The ozone layer is far enough from organisms not to harm them, but also is close enough to the Earth's surface to maintain the proper temperature and hold its layer rigidity. The stratosphere is the correct answer.

Example Question #1 : Ultraviolet Light And Radiation

The ozone layer blocks harmful UV light from reaching Earth's surface. Which of the following best describes the location of the ozone layer? 

Possible Answers:

Troposphere

Mesosphere

Stratosphere

Thermosphere

Correct answer:

Stratosphere

Explanation:

The ozone layer is located in the stratosphere, which is one layer above the troposphere (i.e. where we live).

Example Question #1 : Global Effects And Dynamics

Ozone depletion is caused by the presence of halogen containing compounds in the atmosphere. Which of the following is NOT a halogen?

Possible Answers:

fluorine

chlorine

iodine

neon

bromine

Correct answer:

neon

In Australia, New Zealand, South Africa, Argentina, and Chile, cases of __________ are increasing due to ozone depletion.

Possible Answers:

birth defects

insect-borne disease

cataracts

species extinctions

Correct answer:

cataracts

Cataracts, skin cancer, and high-intensity sunburns are all on the rise in these countries due to ozone depletion and therefore higher exposure to harmful UV rays.

Example Question #4 : Global Effects And Dynamics

Which environmental issue did the 1989 Montreal Protocol address?

Possible Answers:

Biological warfare

Depletion of the ozone layer

Cimate change

Deforestation

Worldwide loss of biodiversity
