Ozone molecules.
Ozone is a gas that is naturally present in our atmosphere, mostly in a region of the stratosphere, also known as the ozone layer. It's between about 10 km and 50 km above the surface of the earth and <span>extends
over the entire globe with some variation.
</span>The ozone in the s<span>tratosphere is considered good because
it absorbs ultraviolet- B (UV-B) radiation from the Sun . If not absorbed,
radiation would reach Earth’s surface in higher amounts that would be more harmful.</span>
The system you are talking about is the solar system.
