Where in the atmosphere does the ozone layer reside?
Stratosphere
Mesosphere
Thermosphere
Troposphere
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.

Ozone depletion is caused by the presence of halogen containing compounds in the atmosphere. Which of the following is NOT a halogen?
neon
fluorine
chlorine
bromine
iodine
Explanation
Fluorine, chlorine, bromine, and iodine are all halogens. Neon on the other hand is an inert noble gas.

The ozone layer blocks harmful UV light from reaching Earth's surface. Which of the following best describes the location of the ozone layer?
Stratosphere
Mesosphere
Thermosphere
Troposphere
Explanation
The ozone layer is located in the stratosphere, which is one layer above the troposphere (i.e. where we live).

In Australia, New Zealand, South Africa, Argentina, and Chile, cases of are increasing due to ozone depletion.
cataracts
birth defects
species extinctions
insect-borne disease
Explanation
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.

Which environmental issue did the 1989 Montreal Protocol address?
Depletion of the ozone layer
Cimate change
Deforestation
Worldwide loss of biodiversity
Biological warfare
Explanation
The Montreal Protocol is an international treaty to phase out production of chemicals that deplete the ozone layer, including CFCs and halocarbons.
