Ozone (O3) is a colorless gas made up of three oxygen atoms bonded together. It is an important molecule in the Earth's atmosphere, where it is found mainly in the stratosphere, which is located about 10 to 50 kilometers above the Earth's surface.

In the stratosphere, ozone plays a crucial role in protecting the Earth from harmful ultraviolet (UV) radiation from the sun. Ozone absorbs much of the UV radiation, preventing it from reaching the Earth's surface where it can cause damage to living organisms and materials.

However, at ground level, ozone can be harmful to human health and the environment. It is a major component of smog and can cause respiratory problems, especially in people with pre-existing lung conditions like asthma. Ground-level ozone is created through the reaction of sunlight with pollutants like nitrogen oxides and volatile organic compounds, which are emitted from sources like vehicles, power plants, and industrial facilities.
