Where in the atmosphere does the ozone layer reside?

Possible Answers:

Troposphere

Stratosphere

Thermosphere

Mesosphere

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 : 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? 

Possible Answers:

Thermosphere

Troposphere

Stratosphere

Mesosphere

Correct answer:

Stratosphere
