The atmospheric layer that contains the ozone layer is called the stratosphere. This layer is located above the troposphere and is essential for life on Earth because the ozone layer absorbs the majority of the sun's harmful ultraviolet (UV) radiation. The protection it offers is crucial for preventing skin cancers and other skin-related issues. Thinning of the ozone layer, due to chemicals like chlorofluorocarbons (CFCs), has raised environmental concerns, prompting global actions to mitigate this issue.
