Which of the following compounds is responsible for ozone depletion? (2019)
Step 1: Understand what ozone is. Ozone is a gas in the Earth's stratosphere that protects us from harmful UV radiation.
Step 2: Learn about chlorofluorocarbons (CFCs). CFCs are man-made chemicals used in products like refrigerators and aerosol sprays.
Step 3: Know how CFCs affect ozone. When CFCs are released into the atmosphere, they eventually reach the stratosphere.
Step 4: Realize that CFCs break down ozone molecules. CFCs release chlorine atoms when they are exposed to UV light, and these chlorine atoms can destroy ozone.
Step 5: Conclude that CFCs are responsible for ozone depletion. Because they break down ozone, CFCs are a major cause of the thinning of the ozone layer.
