Stratosphere:The stratosphere is the layer of the Earth's atmosphere located above the troposphere and below the mesosphere. It contains a high concentration of ozone, which forms the ozone layer.
Ultraviolet (UV) rays: UV rays are a type of electromagnetic radiation emitted by the Sun. They have shorter wavelengths than visible light and can cause damage to living organisms, including skin cancer and cataracts.
Ozone depletion: Ozone depletion refers to the thinning or reduction in concentration of ozone molecules in the ozone layer. This can be caused by human-made substances called ozone-depleting substances (ODS), such as chlorofluorocarbons (CFCs), which contribute to global warming and climate change.
