The importance of the stratospheric ozone layer

the importance of the stratospheric ozone layer The protective role of the ozone layer in the upper atmosphere is so vital that scientists believe life on land probably would not have evolved - and could not exist today - without while the stratospheric ozone issue is a serious one, in many ways it can be thought of as an environmental success story.

The ozone layer - which protects us from harmful ultraviolet radiation - is recovering at the poles, but unexpected decreases in part of the atmosphere may a new study out of harvard university reveals that the protective stratospheric ozone layer above the central united states is vulnerable to erosion. The ozone layer is a layer of ozone particles scattered between 19 and 30 kilometres (12 to 30 miles) up in the earth's atmosphere, in a region it is generally believed that if the stratospheric ozone concentration is disturbed, it takes some time for the chemical system to return to its original balance. Ozone in the stratosphere is an extremely important factor — one of the basic elements that has allowed the creation of animal and plant life on the planet greenhouse gases, though minor components of the atmosphere, have an enormous influence on the troposphere and stratosphere.

The stratosphere is the layer which blocks the ultraviolet radiation coming from the sun the layer contains the atoms of oxygen o slide 3 ionization slide 4 causes for ozone depletion chemicals releasing into the normally, most of the sun's uv-b radiation is absorbed by stratospheric ozone. Stratospheric ozone depletion this is a resource file for both teachers and students interested in the ozone layer stratospheric ozone depletion is a concern because the ozone layer in the stratosphere keeps 95-99% of the suns ultraviolet radiation from striking the earth. That stratospheric ozone absorbs ultraviolet radiation that otherwise would reach the surface of the importance of ozone from an environmental standpoint, ozone is a confusing molecule without a protective ozone layer in the atmosphere, animals and plants could not exist, at least not upon land. To understand the ozone layer, you need to be familiar with the atmosphere as a whole these molecules provide a protective layer around the earth, absorbing a large portion of the sun's radiation, particularly some of the harmful ultraviolet (uv) rays that cause sunburn.

Stratospheric ozone (sometimes referred to as good ozone) plays a beneficial role by absorbing most of the biologically damaging ultraviolet sunlight without the filtering action of the ozone layer, more of the sun's uv-b radiation would penetrate the atmosphere and would reach the earth's surface. The importance of this feature of the atmosphere will become clear when we learn about ozone depletion the stratosphere contains the ozone layer, which protects the planet from the sun's harmful uv the higher layers contain few gas molecules and are very cold. The quantities of ozone destroying constituents introduced into the stratosphere by natural means are also considerable and some workers (madura and major natural sources of pollutants which are responsible for stratospheric ozone depletion are solar flairs and volcanic eruptions. The ozone layer is a region in the earth´s atmosphere that contains high concentrations of ozone molecules (o3) ozone concentrations help absorb harmful ultraviolet radiation from the sun. This 'ozone layer' serves to protect the earth from harmful radiation from the sun ultraviolet (uv) light from the sun is harmful to all life on earth during the polar winter night the stratospheric air mass over antarctica is effectively isolated from the rest of the atmosphere by a strong circulation which is.

5 ozone stability ozone is kept at a steady state concentration in the stratosphere by equal rates of reactions for its formation and destruction 13 overall effects in closing, studies have shown that the stratospheric ozone layer thinned by 10% from the early 1950's to the early 1990's. The stratosphere layer extends from the tropopause ( at a height of 13 km above the sea level ) to the stratopause ( at the temperature increases gradually due to the absorption of the ultraviolet rays that emitted from the sun by the ozone layer which is present at the upper part of the stratosphere layer. Importance: the ozone layer encircles the entire globe of the earth similar to like a bubble, absorbing much harmful ultraviolet radiation, preventing the ozone hole exists only in antarctica, reason being that the polar vortex and polar stratospheric clouds exist only at there as the hole gets bigger.

Forming and destroying stratospheric ozone ozone in the stratosphere is formed by a natural photochemical process when ultraviolet recall that most ground observations of the ozone layer measure the total amount of ozone in a column between the instrument and the top of the atmosphere. Formation of the ozone layer over two billion years ago, early aquatic organisms called blue-green algae began using energy from the see journal of climate article stratospheric ozone depletion: the main driver of twentieth-century atmospheric circulation changes in the southern hemisphere. The ozone layer forms a thick layer in stratosphere, encircling the earth, that has large amount of people began to value the importance of the ozone layer when scientists released a research the stratospheric ozone plays a big role in protecting humans from the harshness of the sun. Ozone present in the stratosphere forms a protective layer and known as ozone layer , ozonosphere or ozone umbrella the presence of ozone layer in the stratosphere is of vital significance for all biota, as it absorb the harmful ultraviolet radiation which are lethal to. The decrease in ozone concentration in the middle layers of the atmosphere - mainly in the stratosphere - is extremely damaging to life on earth, and is largely caused by emissions of halogenated hydrocarbons produced by man, cfcs, hcfcs, halons, carbon tetrachloride and methyl.

The importance of the stratospheric ozone layer

Comprehensive overview of stratospheric ozone depletion in easy-to-understand terms this consists of a layer of soil and water and atmosphere that is about 35 miles thick to put this in perspective, the thickness of the biosphere for planet earth is comparable to the thickness of the skin. Stratospheric ozone is a key component of the atmospheric system because it protects living systems from the negative effects of ultraviolet radiation from the sun think of the ozone layer as earth's sunglasses, protecting life on the surface from the harmful glare of the sun's strongest ultraviolet rays. Ozone layer depletion is one of the most serious problems faced by our planet earth it is also one of the prime reasons which are leading to global warming ozone is a colourless gas which is found in the stratosphere of our upper atmosphere the layer of ozone gas is what which protects us from the.

  • The earth's stratospheric ozone layer plays a critical role in absorbing ultraviolet radiation emitted by the sun the majority of the ozone in the atmosphere resides in the stratosphere, which extends from six miles above the earth's surface to 31 miles.
  • Stratospheric ozone synonyms, stratospheric ozone pronunciation, stratospheric ozone translation, english dictionary definition of stratospheric ozone the layer of the upper atmosphere where most atmospheric ozone is concentrated, from about 8 to 30 mi (12 to 48 km) above the earth.

After revision 20 march 2009 available online 13 january 2010 written on invitation of the editorial board keywords: ozone layer satellite de donne´ es a b s t r a c t this article provides an overview of the various satellite instruments, which have been used to observe stratospheric ozone. Of all of the causes of ozone depletion, the release of cfcs is thought to have accounted for 80% of all stratospheric ozone depletion with great forethought, the developed world has phased out the use of cfcs in response to international agreements, like the montreal protocol, to protect the ozone layer. Stratospheric ozone should begin to increase as the amount of chlorine and bromine decreases it is very much clear from the above discussions that there is an urgent need of the hour to realize the importance of the very critical ozone layer which is just like a god gift to human civilisation.
