Thesis ozone layer depletion

Cosmic radiation threatens us because of ozone layer depletion. Such organization will make your essay more persuasive and draw people attention to the conclusion in that you will express your standpoint and your vision of problem-solving.

It is expected to recover around Cyanobacteria are sensitive to UV radiation and would be affected by its increase. If stratospheric conditions become more severe cooler temperatures, more clouds, more active chlorineglobal ozone may decrease at a greater pace.

These combine quickly with an oxygen molecule to form ozone. Pinotubo in the Philippines.

Depletion ozone layer essay

It is calculated that a CFC molecule takes an average of about five to seven Thesis ozone layer depletion to go from the ground Thesis ozone layer depletion up to the upper atmosphere, and it can stay there for about a century, destroying up to one hundred thousand ozone molecules during that time.

Hence, every student has something to say and to suggest the way of solving the problem. In addition, increased surface UV leads to increased tropospheric ozone, which is a health risk to humans.

One example of ozone depletion is the annual ozone "hole" over Antarctica Exit that has occurred during the Antarctic spring since the early s.

The process by which the clouds remove NO 2 from the stratosphere by converting it to nitric acid in the PSC particles, which then are lost by sedimentation is called denitrification.

These ozone molecules absorb ultraviolet UV light, following which ozone splits into a molecule of O 2 and an oxygen atom.

It is expected to recover around It was thus realized that there is a growing probability of damage to ozone layer by human activities. In twenty nations, including most of the major CFC producers, signed the Vienna Convention for the Protection of the Ozone Layerwhich established a framework for negotiating international regulations on ozone-depleting substances.

The decrease in ozone-depleting chemicals has also been significantly affected by a decrease in bromine -containing chemicals.

These elements are found in stable organic compounds, especially chlorofluorocarbonswhich can travel to the stratosphere without being destroyed in the troposphere due to their low reactivity. It has a peak concentration 10 mg kg-1 in the stratosphere.

This converts a single O 2 into two atomic oxygen radicals. Contact Us to ask a question, provide feedback, or report a problem. They identify key chemical reactions and transport processes that bring CFC photolysis products into contact with ozone.

Molecules of diatomic oxygen, the form of oxygen with which most the people are familiar, contain two atoms each, as shown the formula O2. If stratospheric conditions become more severe cooler temperatures, more clouds, more active chlorineglobal ozone may decrease at a greater pace.

Ozone Layer Depletion

So far, ozone depletion in most locations has been typically a few percent and, as noted above, no direct evidence of health damage is available in most latitudes. These low temperatures form cloud particles.

CFCs released up to amount to 15 million tones.

Basic Ozone Layer Science

Given the longevity of CFC molecules, recovery times are measured in decades. Reactions that take place on polar stratospheric clouds PSCs play an important role in enhancing ozone depletion. Fahey, an atmospheric scientist at the National Oceanic and Atmospheric Administrationfound that the drop in ozone would be from 1—2 percent if a fleet of supersonic passenger aircraft were operated.

Glaciers melting is one of the worst effect of climate change. Anthropogenic damage to the ozone layer: No significant natural sources have ever been identified for these compounds—their presence in the atmosphere is due almost entirely to human manufacture.

Ozone Depletion: Essay on Ozone Layer Depletion

During winter, even though PSCs are at their most abundant, there is no light over the pole to drive chemical reactions. McElroy and Wofsy extended the work of Rowland and Molina by showing that bromine atoms were even more effective catalysts for ozone loss than chlorine atoms and argued that the brominated organic compounds known as halonswidely used in fire extinguishers, were a potentially large source of stratospheric bromine.

Molecules of diatomic oxygen, the form of oxygen with which most the people are familiar, contain two atoms each, as shown the formula O2. Both oxygen produces ozone and anthropogenic human caused sources.

The Montreal and Vienna conventions were installed long before a scientific consensus was established or important uncertainties in the science field were being resolved. There are no significant trends in the tropics, largely because halogen-containing compounds have not had time to break down and release chlorine and bromine atoms at tropical latitudes.

Ozone depletion

The atomic oxygen radicals then combine with separate O 2 molecules to create two O 3 molecules. Recent research primarily since the Montreal Protocol shows that many humans have less than optimal vitamin D levels. As mentioned above, when such ozone-depleting chemicals reach the stratosphere, they are dissociated by ultraviolet light to release chlorine atoms.

In particular, in the U. The autobiography of my mother essay for college The autobiography of my mother essay for college gardie house bressay dress jenny holzer truisms and essays on education methodist view on euthanasia essay. The formation of end products essentially remove Cl from the ozone depletion process.

We can give you some good examples of thesis statements about global warming. High solar activity is a serious effect of ozone layer depletion. Cosmic radiation threatens us because of ozone layer depletion. Oxygen quantity reduction can cause greenhouse effect.
