Description:
The correct answer is:
✅ Stratosphere
Why?
The ozone layer is located in the stratosphere, 10–30 miles (15–50 km) above Earth’s surface.
Key Role: Absorbs 97–99% of the Sun’s harmful UV radiation, protecting life below.
Why Not the Others?
❌ Troposphere: Closest to Earth (weather occurs here), but ozone here is a pollutant.
❌ Mesosphere: Too high (50–85 km); meteors burn up here.
Fun Fact: The ozone hole (caused by CFCs) is slowly healing thanks to the Montreal Protocol! 🌍✨
Bonus: Ozone smells like chlorine—it’s what gives thunderstorms their "clean" scent! ⚡👃
