The ozone layer was discovered by 2 French physicists named Henri Buisson and Charles Fabry in 1913. The ozone layer is concentrated in stratosphere. Ozone is a molecule that contains 3 oxygen atoms. These molecules are continuously formed and destroyed in this layer. This ozone...
In 1974, modelling first pointed to increasing levels of chlorofluorocarbons (CFCs, which were often used in aerosol spray cans, foams and cooling devices) as a source of chlorine radicals in the stratosphere that could catalytically destroy ozone5. The dramatic discovery in the mid-1980s of the...
How is a good stratospheric ozone formed? Stratosphere: The stratosphere is a layer of the atmosphere that is just above the troposphere. The troposphere is the layer of the atmosphere that we live in while the stratosphere is the layer where airplanes and weather balloons usually fly. ...
The Formation of Smog Photochemical smog (or just smog for short) is a term used to describe air pollution that is a result of the interaction of sunlight with certain chemicals in the atmosphere. One of the primary components of photochemical smog isozone. While ozone in the stratosphere prot...
The ozone layer refers to a region of the atmosphere approximately 20 kilometers thick where there is a high concentration of ozone molecules. About 90 percent of the ozone layer is found in the stratosphere while another 10 percent is in the upper troposphere just below the stratosphere. ...
Ozone is found naturally in small concentrations in thestratosphere, a layer of Earth's upper atmosphere. In this upper atmosphere, ozone is made when ultraviolet light from thesunsplits an oxygen molecule (O2), forming two single oxygenatoms. If a freed atom collides with an oxogen molecule...
Nuclear Winter and the Ozone Some scientists predict that nuclear winter would be followed by an even harsher spring. They theorize that the sunlight bounced back up from the smokecloudswould heat up nitrogen oxides in the stratosphere. At high temperatures, the nitrogen oxides, which formed due ...
听力原文:M: Ozone is an extremely active gas comprised of three atoms of oxygen. Ozone exists naturally in the Earth's upper atmosphere, the stratosphere, where it shields the Earth from the sun's ultraviolet rays. However, ozone found close to the Earth's surface, called ground-level ozone...
How does the atmosphere protect life on earth? Discuss how hydrocarbons contribute to the formation of ozone in the atmosphere. Why does the earth's atmosphere contain only small amounts of carbon dioxide? Explain why CFCs eventually make their way into the stratosphere even though most c...
