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.

- In the stratosphere, ozone is mainly emitted by ultraviolet radiation. When even low-energy ultraviolet radiation is absorbed by an ozone molecule,...
- Ozone molecules (O3) have three atoms of oxygen. There are two distinct layers of ozone present in the Earth’s atmosphere. The troposphere, the lay...
- They kill ozone molecules as chlorine and bromine atoms come into contact with ozone in the stratosphere. About 100,000 ozone molecules will be kil...
- According to a recent report, the ozone layer is beginning to regenerate and has the ability to fully restore. Published in Nature, a research pape...
- In the stratosphere (a layer of the atmosphere between 10 and 40 km above us), much of the ozone remains where it serves as a barrier to protect th...
Jun 14, 2024 · 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 ).

Oct 19, 2023 · 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.
2 days ago · View the latest status of the ozone layer over the Antarctic, with a focus on the ozone hole. Satellite instruments monitor the ozone layer, and we use their data to create the images that depict the amount of ozone.
Mar 13, 2023 · Why is the ozone layer important? The ozone layer absorbs 97% to 99% of the sun’s incoming ultraviolet radiation (UV-B). This is fundamental to protecting life on Earth’s surface from exposure to harmful levels of this radiation, which can damage and disrupt DNA.
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.
