The ozone layer is a region of Earth's stratosphere that contains high concentrations of ozone (O3) molecules. Located 10-30 miles above Earth's surface, this invisible shield absorbs most of the Sun's harmful ultraviolet radiation, making life on Earth possible. Without this protection, UV radiation would sterilize the planet's surface.
đŦ Key Concepts
Located in the stratosphere (10-30 miles up)
Contains concentrated ozone (O3) molecules
Absorbs 97-99% of harmful UV radiation
Essential for protecting life on Earth
Environmental Fact!
If you could compress all the ozone in the atmosphere into a layer at sea level, it would only be about 3 millimeters thick - thinner than a coin!
đ¯ Learning Objectives
Understand the critical role of the ozone layer in protecting Earth and how human activities have threatened this natural shield.
