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.
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.
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.
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 ).
Jan 10, 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.
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.
What is the ozone layer, and why is it so important? Over the last 50 years, holes in the ozone layer have opened up. Why does that matter for life on Earth? Hannah Ritchie. How we fixed the ozone layer. Hannah Ritchie (published at Works in Progress) Images and satellite measurements of the ozone layer. NASA Ozone Watch
Oct 7, 2021 · Learn about the ozone layer and how human activities deplete it. This page provides information on the chemical processes that lead to ozone layer depletion, and scientists' efforts to understand them.
The ozone layer is a zone in the stratosphere in which about 90% of atmospheric ozone can be found. It exists between about 15 to 35 km in altitude. Ozone is produced at this altitude when...
ozone layer, or ozonosphere, Region in the upper atmosphere, about 9–22 mi (15–35 km) high, with significant concentrations of ozone, formed by the effect of solar ultraviolet (UV) radiation on oxygen and also present in trace quantities elsewhere in Earth’s atmosphere.
