Where is the ozone layer of the Earth?
At ground level
The stratosphere
Within the crust
In space
Which one of these is the molecular formula for ozone?
The ozone layer is important because it blocks out much of the sun's (a) rays.
Ozone is created primarily by (a) . When high-energy (b) rays strike an
(c) molecule (O2), they split the molecule into two single atoms. A freed atom then combines with another molecule to form a molecule of ozone ( (d) ).
Which of these is an ozone-depleting chemical?
A single atom of chlorine, acting as a catalyst, can destroy about ________ molecules of ozone.
2
100
1,000

Thinning of the ozone layer
Thinning ice sheets
Ocean currents
What atmospheric conditions contributed to the formation of the ozone hole over Antarctica?
High CO2 concentrations
High humidity
Extremely cold temperatures
Warm temperatures
What was the treaty that required countries to phase out the use of ozone-depleting chemicals?
Geneva Convention
