Causes of depletion of the ozone layer

causes of depletion of the ozone layer What causes ozone depletion the ozone layer depletion is caused by the human activity (75 to 85%), natural sources (15 – 20%) and volcanic eruptions (1 to 5%), and was first observed in the late 1970s by scientists.

Ozone layer and causes of ozone depletion: ozone layer is a deep layer in earth's atmosphere called stratosphere that contain ozone which is a naturally occurring molecule containing three oxygen atoms. What is ozone layer depletion the ozone is a layer of gases in the stratosphere, which is a thick (20 km thick, to be precise) layer of gas that rests about 30-50 km above the surface of the earth. The major cause for depletion of ozone in the ozone layer is thought to be chlorofluorocarbons — or refrigerants (commonly caused ozone depleting chemicals) once these chemicals get up there they last a long time because the are catalysts for the chemical process that deplete ozone. What causes ozone depletion many well accredited scientific studies have provided ample evidence for what effects are behind the depletion of the ozone predominantly, researchers have found that it is the introduction of artificial chemicals created by humans which contain bromine or chlorine.

Destruction of the ozone layer - the causes chlorofluorocarbons (cfcs) have been identified as the main cause of the destruction to the ozone layer, but there are also compounds containing bromine, other halogen compounds and also nitrogen oxides which cause damage. The ozone layer has historically protected the earth from the harmful uv rays, although in recent decades this protection has diminished due to stratospheric ozone depletion figure \(\pageindex{1}\): these images from the total ozone mapping spectrometer (toms) show the progressive depletion of ozone over antarctica from 1979 to 1999. The ozone layer is a belt of the naturally occurring gas ozone it sits 93 to 186 miles (15 to 30 kilometers) above earth, and serves as a shield from the harmful ultraviolet b (uvb) radiation.

Major and minor sources of stratospheric chlorine stratospheric chlorine is at present the major catalyst of ozone depletion since this area is considered a little more contriversial i have referenced it more heavily. A natural causes of depletion of ozone layer ozone layer has been found to be affected by certain natural phenomena such as sun-spots and stratospheric winds but this has been found to cause not more than 1-2% depletion of the ozone layer and the effects are also thought to be only temporary it is also believed that the. The ozone layer is a deep blanket in the stratosphere made up of comparatively high concentration of the ozone as a result of its chemical composition, ozone is regarded as a special type of oxygen as it contains three oxygen molecules (o3) as opposed to the usual two oxygen molecules (o2. Starting with the 1970s, scientists decided to analyze ozone layer depletion many environmentalists and researchers have been analyzing this topic over the years to establish the causes and the effects of ozone depletion.

Causes of ozone layer depletion: the main cause of ozone layer depletion is the build-up of cfcs (chlorofluorocarbons) in the atmosphere when the cfcs reach the upper atmosphere, high uv radiation reacts with these and releases chlorine atoms. The connection between ozone layer depletion and uvb radiation reduced ozone levels as a result of ozone depletion ozone depletiona chemical destruction of the stratospheric ozone layer beyond natural reactions stratospheric ozone is constantly being created and destroyed through natural cycles. The ozone layer helps protecting the ultraviolet radiations of the sun reaching earth's surface but the refrigerants cause destruction of ozone layer and produce the hole in the ozone layer this article describes how ozone is measured in the atmosphere, how ozone layer is destroyed, various emissions that cause ozone layer depletion, halogens that destroy ozone layer, impact of chlorine and. Ozone layer depletion means it is the reduction of the ozone amount in the stratosphere it is not like pollution that has lots of causes and type, ozone depletion comes in the category of major human activity.

Causes of depletion of the ozone layer

Ozone depletion: ozone depletion, gradual thinning of earth’s ozone layer caused by the release of chemical compounds containing gaseous chlorine or bromine from industry and other human activities the thinning is most pronounced in the polar regions, especially over antarctica. Ozone depletion causes increases in uv rays’s effects on aquatic ecosystems by: 1 decreasing the abundance of phytoplankton – affects the food stock for fishes and the absorption of co2 2 decreasing the diversity of aquatic organisms – reduces food stock and also destroys several fish and amphibians. The origin, causes, mechanisms and bio effects of ozone layer depletion as well as the protective measures of this vanishing layer the chlorofluorocarbon and the halons are potent ozone ozone layer depletion and its effects: a review causes the two oxygen atoms to split apart if a freed atom bumps into another o2,. The ozone in the ozone layer is being broken down by chlorine atoms from chlorofluorocarbon (cfc) molecules and bromine atoms from halons cfcs and halons are produced by humans used in many applications such as refrigerants, anaesthetics, aerosols, fire-fighting equipment and the manufacture of materials such as stryrofoam.

Causes of ozone layer depletion unfortunately, the ozone layer isn’t nearly as stable as was previously thought human actions can have an enormous effect upon it in its entirety and due to upper stratospheric currents, the lack of concentration tends to pool in certain places. Thus, due to depletion of the ozone layer, not only the temperature increases, but also the level of water that causes floods to prevent the depletion of the ozone layer due to cfc refrigerants, an international agreement called montreal protocol was signed by various countries in 1987.

The ozone layer, 12 to 19 miles above earth, is the region of the atmosphere where the physical-chemical conditions are most favorable for the ozone-oxygen cycle when a molecule such as oxygen or ozone is dissociated, the molecular pieces fly apart at high velocity, instantly converting all the bond energy into kinetic energy of translation. Ozone layer depletion is a serious threat to environment and causes of ozone layer depletion have now initiated a hole in ozone layer which is very bad. The term ‘ozone hole’ refers to the depletion of the protective ozone layer in the upper atmosphere (stratosphere) over earth's polar regions people, plants, and animals living under the ozone hole are harmed by the solar radiation now reaching the earth's surface—where it causes health problems, from eye damage to skin cancer. Ozone layer depletion the ozone layer is a thin layer in the atmosphere at an altitude of about 20-30 km that has a high concentration of ozone gas it is made up of three atoms of oxygen and is represented as o 3.
