Ozone is a simple chemical that can cause tremendous effects on living things. Understanding the technicalities of the ozone layer is crucial to identifying the problems caused by it. Below are some of the brilliant facts about the ozone layer.

2025年1月17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).

2023年1月10日 · 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.

2024年9月23日 · 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 …

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.

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.

2024年12月2日 · Ozone, a molecule made up of three oxygen atoms, plays a crucial role in our atmosphere. Found in two layers, the stratosphere and the troposphere, it can be both a protector and a pollutant. In the stratosphere, ozone forms a …

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.

2024年11月18日 · Why is the ozone layer important? What is ozone depletion, and how does it occur? What is the ozone hole? What is the connection between ozone depletion and climate change? How do we know that natural sources are not responsible for ozone depletion? What is being done about ozone depletion?

2024年9月17日 · 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.
