16 paź 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. Approximately 90 percent of the atmosphere’s ozone occurs from 10–18 km (6–11 miles) to about 50 km (about 30 miles) above Earth’s surface.
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.
13 mar 2023 · 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.
10 sty 2023 · What is the ozone layer, and why does it matter? Human activity has damaged this protective layer of the stratosphere, but scientists say the ozone layer is on track for recovery.
19 paź 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.
23 wrz 2024 · Ninety percent of the ozone in the atmosphere sits in the stratosphere, the layer of atmosphere between about 10 and 50 kilometers altitude. The natural level of ozone in the stratosphere is a result of a balance between sunlight that creates ozone and chemical reactions that destroy it.
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.
