First and foremost, the Earth’s atmosphere contains a layer of gases (also remarked as air) that forms Associate in Nursing envelope around Earth. The atmosphere is stratified into 5 (5) layers that square measure as follows: The layer, the layer, the layer, layer and also the layer. This envelope of gases is maintained around Earth by the influence of the force of gravity. Notable functions of the Earth’s atmosphere include:
- Absorption of harmful actinic radiation (by the ozonosphere within the Earth’s stratosphere)
- Generation of constant pressure Earth’s surface to make sure continual presence of liquid water
- Warming of Earth’s surface through heat retention (Greenhouse effect)
- Constant regulation of diurnal temperature variation etc.
The ozonosphere additionally called ‘ozone shield’ or ‘ozonosphere’ is one that is created from a mixture of Associate in Nursing atomic number 8 atom (O) with Associate in Nursing atomic number 8 molecule (O2) yielding gas (O3) in massive amounts, that successively ends up in the assembly of a protecting layer within the Earth’s atmosphere.
The ozonosphere is frequently generated through the ozone-oxygen cycle inside the layer, within which ultraviolet rays cause Associate in Nursing gas molecule to separate into Associate in Nursing atomic number 8 atom (O) Associate in Nursingd an atomic number 8 molecule (O2). The atomic number 8 atom then, combines with a close-by atomic number 8 molecule (O2) to convey gas. This method may occur naturally within the Earth’s layer through picture dissociation or by artificial means within the laboratory through the utilization of a silent arc or spark.
However, the thickness of this protecting layer of gas within the layer varies geographically and seasonally e.g the ozonosphere has been found to be thinnest throughout fall, while, it’s thickest throughout spring whereas peak concentrations at totally different altitudes vary from one region of the globe to the opposite. It should be noted that the thickness of the ozonosphere refers to the quantity of gas that may be found during a column of a given space or geographical location.
Furthermore, considerably high amounts of gas is typically made within the tropics and transported towards the poles by stratospheric wind patterns. This method, remarked as ‘Brewer-Dobson circulation’ within the hemisphere is to blame for the variation within the thickness of the ozonosphere throughout spring and thinness of the ozonosphere throughout fall.
