Ozone layer - Wikipedia
The ozone layer or ozone shield is a region of Earth's stratosphere that absorbs most of the Sun's ultraviolet radiation. It contains a high concentration of ozone (O 3 ) in relation to other parts of the atmosphere, although still small in relation to other gases in the stratosphere.

2024年10月16日 · ozone layer, region of the upper atmosphere, between roughly 15 and 35 km (9 and 22 miles) above Earth’s surface, containing relatively high concentrations of ozone molecules (O 3).
What is the ozone layer, and why is it important?
2023年3月13日 · The stratosphere includes the zone commonly called the ‘ozone layer’. It plays a crucial role in keeping the planet habitable by absorbing potentially dangerous ultraviolet (UV-B) radiation from the sun. Before its depletion, the ozone layer typically absorbed 97 to 99% of incoming UV-B radiation.

2023年10月19日 · The ozone layer is one layer of the stratosphere, the second layer of Earth’s atmosphere. The stratosphere is the mass of protective gases clinging to our planet. The stratosphere gets its name because it is stratified, or layered: as elevation increases, the stratosphere gets warmer.
Ozone Layer - Our World in Data
The ozone layer plays a vital role in making the planet habitable for us and other species. High in the atmosphere – between 10 to 50 kilometers above the earth's surface – the ozone layer absorbs most of the sun’s ultraviolet radiation.

The Ozone Layer. Near the ground, ozone is an air pollutant that causes lung damage and asthma attacks. But 10 to 30 miles above the Earth’s surface (16-48 km), ozone molecules protect life on Earth. They help shield our planet from harmful solar radiation.
Science - Ozone Basics - National Oceanic and Atmospheric …
Most ozone (about 90%) resides in a layer that begins between 6 and 10 miles (10 and 17 kilometers) above the Earth's surface and extends up to about 30 miles (50 kilometers). This region of the atmosphere is called the stratosphere. The ozone in this region is commonly known as the ozone layer.
