Ozone layer - Simple English Wikipedia, the free encyclopedia.

Ozone Depletion Atmospheric ozone layer depletion is a serious problem currently facing the world. The ozone layer protects humans, animals, and plants from harmful ultraviolet rays. Money and time are being spent on ozone repair, but the problem still exists. The ozone layer is a region of the stratosphere containing ozone, or O3 gas. The ozone layer is essential to both plant and animal life.

What does Ozone depletion mean? - eschooltoday.

Ozone depletion, gradual thinning of Earth’s ozone layer in the upper atmosphere 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 is a major environmental problem because it increases the amount of ultraviolet (UV.The ozone layer is a layer of ozone high up in the Earth's atmosphere stratosphere, between approximately 10 kilometres and 50 kilometres above Earth’s surface.The exact amount of ozone varies, depending on the seasons and the location. This layer absorbs between 93 and 99 per cent of the ultraviolet radiation from the sun. This radiation is dangerous to living organisms on Earth.The ozone layer sits between the Sun and us. Without the Sun's warmth, it would be too cold to live on Earth, but the Sun also gives off harmful ultraviolet rays, or UV rays for short. These rays.


This study was conducted at University of Gujrat during 2014-2015 as a term paper for Master of Philosophy. The data regarding effect of ozone depletion on human was reviewed and compiled as a.The Antarctic ozone hole is caused by human-produced chlorine-containing chlorofluorocarbons (CFCs) and bromine-containing halons. These compounds had a variety of commercial uses, including hair sprays, refrigerants, and fire suppressants. This story about the cause of ozone depletion was originally developed for the NASA hyperwall, where nine different animations can be shown simultaneously.

Short Essay On Ozone Depletion

Ozone depletion consists of two related events observed since the late 1970s: a steady lowering of about four percent in the total amount of ozone in Earth's atmosphere (the ozone layer), and a much larger springtime decrease in stratospheric ozone around Earth's polar regions. The latter phenomenon is referred to as the ozone hole.There are also springtime polar tropospheric ozone depletion.

Ozone is a gas that is present in the ozone layer in the stratosphere of the Earth.There, it will absorb almost all ultraviolet light which is harmful to many organisms.The term Ozone depletion can refer to a number of distinct, but related phenomena:. Since about the 1970s, there has been a decrease in total volume of the Ozone in the ozone layer, of about 4%, per decade.

Montreal Protocol, international treaty, adopted in Montreal on Sept. 16, 1987, that aimed to regulate the production and use of chemicals that contribute to the depletion of Earth’s ozone layer. Initially signed by 46 countries, the treaty now has nearly 200 signatories. In the early 1970s.

The Legislative Council passed the Ozone Layer Protection (Products Containing Scheduled Substances) (Import Banning) (Amendment) Regulation on 2 December 2009. The Amendment Regulation extends the banning of the import of controlled products (including refrigeration and air-conditioning equipment, aerosol products such as metered dosed inhalers, insulation panel and pre-polymer) containing.

Short Essay On Ozone Depletion

When the scale of ozone depletion over Antarctica became apparent in 1985, it didn’t take long for the international community to reach a consensus on what needed to be done. If it weren’t for swift political action, ozone depleting chemicals would have continued to accumulate in the atmosphere increasing the size of the Antarctic ozone hole as well as thinning the ozone layer elsewhere.

Short Essay On Ozone Depletion

However, given that ozone itself is a greenhouse gas, ozone depletion plays an important role in the global climate system, and vice versa climate change strongly affects the global ozone layer. The effects of climate change on stratospheric processes can be direct (by cooling the stratosphere) or indirect (by influencing stratospheric dynamics and composition). Furthermore, ozone is.

Short Essay On Ozone Depletion

Ozone depletion is the term commonly used to describe the thinning of the ozone layer in the stratosphere. Ozone depletion occurs when the natural balance between the production and destruction of ozone in the stratosphere is tipped in favor of destruction. Human activity is the major factor in tipping that natural balance, mostly from releasing artificial chemicals, known as ozone-depleting.

Short Essay On Ozone Depletion

Ozone layer definition, the layer of the upper atmosphere where most atmospheric ozone is concentrated, from about 8 to 30 miles (12 to 48 km) above the earth, with the maximum ozone concentration occurring at an altitude of about 12 miles (19 km). See more.

Conclusions: Looking back over the scientific investigation of ozone depletion, we can see how the Molina-Rowland hypothesis evolved with new data.When chlorine nitrate, a chemical that ties up chlorine in an ozone-safe form, was added to the hypothesis, the expected amount of ozone loss decreased.

Short Essay On Ozone Depletion

The ozone layer acts as a natural filter, absorbing most of the sun's burning ultraviolet (UV) rays.Stratospheric ozone depletion leads to an increase in UV-B that reach the earth's surface, where it can disrupt biological processes and damage a number of materials. The fact that UV-B can cause biological effects is well demonstrated by the familiar sunburn that follows overexposure to the sun.

Short Essay On Ozone Depletion

IntroductionThe ozone layer is found in the upper stratosphere and its primary function is to filter ultraviolet short-wave radiation that comes from the sun. Ozone gas absorbs UV radiation. The 'hole' in the ozone layer was first noted in the 1980's, and is of concern as increased levels of UV radiation can leads to increased levels of skin cancer and eye cataracts.At first the ozone hole was.

Essay on Effects of Ozone Layer Depletion. Article shared by. The upper layer of the atmosphere surrounded by ozone (15 to 30 Kms) is known as ozonosphere. Ozone layer is a protective stratospheric layer, also known as ozone umbrella. Ozone concentration differs by about 10 ppm in stratosphere compared to 0.05 ppm in troposphere. It acts as a protective shield for the man, animals and plants.
