Found primarily in the stratosphere, about 15 to 30 km above the Earth's surface.
The ozone layer is a vital shield that protects all life on Earth by absorbing approximately 98% of the sun's harmful ultraviolet (UV) radiation. Understanding its formation, depletion, and recovery is essential for students, environmentalists, and researchers. ozone layer ppt free download
When CFCs reach the stratosphere, UV light breaks them down, releasing chlorine atoms . One single chlorine atom can destroy over 100,000 ozone molecules. Found primarily in the stratosphere, about 15 to
The primary culprits are human-made chemicals like Chlorofluorocarbons (CFCs) , halons, and carbon tetrachloride. When CFCs reach the stratosphere, UV light breaks
If you are looking for an , the following guide outlines the essential slides and data points you should include to create a professional presentation. Core Content for Your Ozone Layer PPT 1. Introduction: What is the Ozone Layer? Composition: Ozone ( O3cap O sub 3 ) is a gas composed of three oxygen atoms.
Volcanic eruptions and stratospheric winds can cause minor fluctuations (roughly 1–2%), but human activity remains the dominant driver. 4. The "Ozone Hole" Facts Ozone Layer Depletion Overview | PDF - Scribd
Note that while stratospheric ozone protects us, "ground-level" ozone (in the troposphere) is a harmful pollutant and a key component of smog. 2. The Process of Formation (The Chapman Mechanism) Step 1: Solar UV radiation breaks apart oxygen molecules ( O2cap O sub 2 ) into individual oxygen atoms ( Step 2: These highly reactive atoms combine with other O2cap O sub 2 molecules to form ozone ( O3cap O sub 3 Formula: 3. Causes of Ozone Depletion
