Here's how it works:
* UV Radiation: The sun emits a range of radiation, including UV radiation. UV radiation is divided into three types: UVA, UVB, and UVC.
* Ozone Layer: The ozone layer in the stratosphere contains high concentrations of ozone (O3) gas.
* Absorption: Ozone effectively absorbs UVB radiation. When a UVB photon strikes an ozone molecule, it breaks the molecule apart. This process converts UVB radiation into heat, preventing it from reaching the Earth's surface.
Why is this important?
* Protection from Harmful Radiation: UVB radiation is harmful to living organisms, causing skin cancer, cataracts, and damage to plants. The ozone layer acts as a shield, protecting life on Earth.
* Balance: The interaction between ozone and UV radiation is a delicate balance. The ozone layer is constantly being formed and destroyed through natural processes. However, human activities can disrupt this balance, leading to ozone depletion and increased UV radiation reaching the Earth's surface.
