Example Questions
Example Question #1 : Global Effects And Dynamics
Where in the atmosphere does the ozone layer reside?
Mesosphere
Stratosphere
Troposphere
Thermosphere
Stratosphere
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 : Global Effects And Dynamics
The ozone layer blocks harmful UV light from reaching Earth's surface. Which of the following best describes the location of the ozone layer?
Mesosphere
Troposphere
Thermosphere
Stratosphere
Stratosphere
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?
fluorine
neon
bromine
iodine
chlorine
neon
Fluorine, chlorine, bromine, and iodine are all halogens. Neon on the other hand is an inert noble gas.
Example Question #1 : Global Effects And Dynamics
In Australia, New Zealand, South Africa, Argentina, and Chile, cases of __________ are increasing due to ozone depletion.
species extinctions
insect-borne disease
birth defects
cataracts
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 #2 : Global Effects And Dynamics
Which environmental issue did the 1989 Montreal Protocol address?
Cimate change
Worldwide loss of biodiversity
Depletion of the ozone layer
Deforestation
Biological warfare
Depletion of the ozone layer
The Montreal Protocol is an international treaty to phase out production of chemicals that deplete the ozone layer, including CFCs and halocarbons.
