How can ozone layer formed?

Answer 1

Ozone in the ozone layer is formed when UV-C from the Sun dissociates an oxygen molecule, and some of those now-loose oxygen molecules connect with an oxygen molecule to form ozone. Ozone in a rain storm is made by lightning dissociating oxygen molecules, and the rest occurs as above. Ozone in tropospheric ozone pollution is directly made by internal combustion engines, but mostly by photoproduction when NOx (from combustion exhaust), and VOC (unburned fuel and "cow farts") are converted by purple or more energetic light into ozone and nitrogen gas (and the VOC just moves on). Ozone in medical / industry / water treatment is made either by UV lamps (for low concentrations) or by electrical discharge dissociating oxygen molecules, and the rest occurs as above. Ozone in the bloodstream is made by white blood cells (along with other powerful oxidants) in very tiny areas, when fighting infection at a site. The resultant of this fight is called "inflammation" or "swelling".

Answer 2

More than 99.9% of the Earth's atmosphere is made up of the gases nitrogen, oxygen and argon. The trace gas ozone only occurs in very small quantities. While nitrogen and oxygen are vertically (at right angles to the Earth's surface) equally distributed, the distribution of ozone varies with height and reaches its maximum amount (concentration) at around 20 km, in the stratosphere. The normal atmosphere reaches up to about 120km above the Earth's surface, and pressure reduces exponentially with height. If one were to take the whole air-mass over a particular area on the Earth's surface and press it so that was all under the same pressure as the air at ground level, then that air would take up a space 8km high. Of these 8km, ozone would make up only 3mm! It is in this way that the amount of ozone in the atmosphere is described. The units are called Dobson units (DU): 300 DU mean 3mm of the air column is made up of ozone. Ozone is a relation of oxygen. It is made of three oxygen atoms (O3) ,unlike the oxygen we breathe and which plays an important role in the burning process, which is made of two oxygen atoms. Ozone is produced when oxygen (O2) is broken up into its atoms (O) by high-energy solar radiation, of wavelengths below 240 nanometers. (1000000000 nanometer (nm) is the same as one meter.) O3 protects the Earth's surface from harmful sun rays. Ozone absorbs above all radiation from the sun which lies in the UV-B region: (280-315 nm wavelength) and through this absorption is split up again into an oxygen atom and an oxygen molecule.

Answer 3

Ozone was formed by a chemical process. When oxygen is treated with UV radiations oxygen gets converted into ozone.

Answer 4

Ozone is formed naturally. It is formed by UV and lightening.

Answer 5

Ozone is a tri oxygen molecule. It is formed in a natural process by the action of UV light on oxygen molecule.
