Ozone (O3) is a molecule made up of three oxygen atoms. It is found in the Earth's stratosphere, a layer of the atmosphere that extends from about 10 to 50 kilometers above the Earth's surface.
Here's how ozone acts as a shield:
* UV Absorption: Ozone molecules absorb most of the harmful ultraviolet (UV) radiation from the sun. This absorption breaks down the ozone molecules, but also prevents the UV radiation from reaching the Earth's surface.
* The Ozone Layer: The region of the stratosphere with the highest ozone concentration is known as the ozone layer. This layer acts as a vital protective shield for life on Earth.
While oxygen (O2) is also a crucial component of the atmosphere, it doesn't have the same UV filtering properties as ozone.
