Question

Quizplus · Accepted Answer

The ozone layer absorbs ultraviolet energy, which is harmful to life on Earth.

Answer A, B, and D are incorrect. The ozone layer is actually located in the stratosphere, not the troposphere (Choice A is incorrect). While the ozone layer is mainly composed of ozone, it actually only makes up about 3-8% of the gas in the layer, not nearly half (Choice B is incorrect). Finally, the ozone layer does not radiate gamma rays toward Earth, as gamma rays are a form of high-energy radiation that can be harmful to living organisms, whereas the ozone layer actually protects us from harmful radiation (Choice D is incorrect).
