What is the main source of ozone depletion? (2021)
Step 1: Understand what ozone is. Ozone is a gas in the Earth's atmosphere that protects us from harmful UV rays from the sun.
Step 2: Learn about ozone depletion. Ozone depletion means that there is less ozone in the atmosphere, which can lead to more UV rays reaching the Earth.
Step 3: Identify the main cause of ozone depletion. The main substances that cause ozone depletion are called chlorofluorocarbons (CFCs).
Step 4: Know where CFCs come from. CFCs were commonly used in products like refrigerators, air conditioners, and aerosol sprays.
Step 5: Realize the impact of CFCs. When CFCs are released into the atmosphere, they eventually reach the ozone layer and break down ozone molecules, leading to depletion.
