AP Environmental Science Global Change Review

Here's an organized outline for AP Environmental Science Unit 9 reviews. This outline has been adapted from the 2019 Course Description published by College Board. You can use this to build an AP Enviro Unit 9 study guide.

⚡ Read: AP Environmental ScienceUnit 9 Overview 

Ozone

Stratospheric ozone is vital to life on Earth, human activities have caused the depletion of stratospheric ozone. 

  • Chlorofluorocarbons (CFCs) deplete stratospheric ozone.
  • Stratospheric ozone absorbs harmful UV rays preventing them from reaching the Earth’s surface.
  • Hydrofluorocarbons (HFCs) are more reactive than Chlorofluorocarbons (CFCs) and are not ozone-depleting chemicals, they are however still very strong greenhouse gases.

Effects on the World

Humans activities can increase greenhouse gases that can cause human health and environmental problems.
