Questions & Step-by-Step Solutions
Which gas is primarily responsible for the depletion of the ozone layer?
Step 1: Understand what the ozone layer is. It is a layer of ozone gas in the Earth's atmosphere that protects us from harmful ultraviolet (UV) rays from the sun.
Step 2: Learn about gases that can harm the ozone layer. Some gases can break down ozone molecules.
Step 3: Identify the main gas that causes this harm. Chlorofluorocarbons (CFCs) are chemicals that were commonly used in products like refrigerators and aerosol sprays.
Step 4: Know how CFCs affect the ozone layer. When CFCs are released into the atmosphere, they eventually reach the ozone layer and break down ozone molecules, leading to depletion.
Step 5: Conclude that CFCs are primarily responsible for the depletion of the ozone layer.
