Which of the following is a major contributor to the depletion of the ozone layer?

Which of the following is a major contributor to the depletion of the ozone layer?

Step 1: Understand what the ozone layer is. It is a layer in the Earth's atmosphere that protects us from harmful ultraviolet (UV) radiation from the sun.
Step 2: Learn about chlorofluorocarbons (CFCs). These are man-made chemicals that were commonly used in products like refrigerators, air conditioners, and aerosol sprays.
Step 3: Recognize that when CFCs are released into the atmosphere, they rise up and eventually reach the ozone layer.
Step 4: Understand that CFCs break down ozone molecules in the ozone layer, which reduces its ability to protect us from UV radiation.
Step 5: Conclude that CFCs are a major contributor to the depletion of the ozone layer, leading to increased UV radiation exposure.
