Questions & Step-by-Step Solutions
Which chemical compound is primarily responsible for ozone depletion?
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 chemicals that cause ozone depletion. The main chemicals responsible for this are called chlorofluorocarbons, or CFCs.
Step 4: Know where CFCs come from. CFCs were commonly used in products like refrigerators, air conditioners, and aerosol sprays.
Step 5: Understand how CFCs affect ozone. When CFCs are released into the atmosphere, they eventually reach the stratosphere, where they break down and release chlorine atoms that destroy ozone molecules.
