Example Questions
Example Question #1 : Ozone Formation
Where in the atmosphere does the ozone layer reside?
Troposphere
Mesosphere
Thermosphere
Stratosphere
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 : 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?
Mesosphere
Thermosphere
Stratosphere
Troposphere
Stratosphere
The ozone layer is located in the stratosphere, which is one layer above the troposphere (i.e. where we live).
Example Question #1 : Causes And Effects Of Ozone Loss
Ozone depletion is caused by the presence of halogen containing compounds in the atmosphere. Which of the following is NOT a halogen?
fluorine
neon
iodine
bromine
chlorine
neon
Fluorine, chlorine, bromine, and iodine are all halogens. Neon on the other hand is an inert noble gas.
Example Question #2 : Causes And Effects Of Ozone Loss
In Australia, New Zealand, South Africa, Argentina, and Chile, cases of __________ are increasing due to ozone depletion.
cataracts
insect-borne disease
birth defects
species extinctions
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 #1 : Ozone
Which environmental issue did the 1989 Montreal Protocol address?
Deforestation
Cimate change
Depletion of the ozone layer
Worldwide loss of biodiversity
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.
