What is ozone and where is it in the atmosphere?
Correspondingly, where is ozone in the atmosphere?
Ozone is mainly found in two regions of the Earth's atmosphere. 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.
Subsequently, question is, how Ozone is formed? Ozone is a molecule made up of three oxygen atoms, often referenced as O3. Ozone is formed when heat and sunlight cause chemical reactions between oxides of nitrogen (NOX ) and Volatile Organic Compounds (VOC), which are also known as Hydrocarbons.
Also to know, what is ozone How and where is it formed in the atmosphere?
Ozone is produced naturally in the stratosphere when highly energetic solar radiation strikes molecules of oxygen, O2, and cause the two oxygen atoms to split apart in a process called photolysis. Most of the ozone in the stratosphere is formed over the equatorial belt, where the level of solar radiation is greatest.
Why is ozone found in upper atmosphere and not on Earth?
Ozone thus constitutes in the stratosphere a shield that prevents the ultraviolet radiation, which causes biological damage (skin cancer) from passing to the earth's surface. Without ozone in the upper atmosphere, life on earth would not have evolved and could not exist today.
