the ozone layer lies at the boundary of the stratosphere and mesosphere.?

False. The ozone layer is contained mostly in the stratosphere, but is actually located at the lower layer of the stratosphere, adjacent to the troposphere. The mesosphere is situated above the stratosphere.

I believe all the layers create a balance to sustain life on the third planet from the sun. The main layer-the troposphere-is half of the atmosphere and closest to the earth. It contains the natural gases for life and makes our weather. Without it, the water cycle would be impossible. The stratosphere's high stability level lets us fly aircraft within it. The ozone layer which controls how much sun touches our tan is in the stratosphere. Most potentially dangerous meteorites burn away in the mesosphere. The space shuttle can only orbit around the world with the thermosphere. That's where auroras are made. The upper limits(what I like to call the "crust" of our atmosphere) is the exosphere. I hope this helped.

Troposhere is closest to the Earth, and contains weather, and mesosphere is the coldest layer out of all four layers

The atmosphere reaches over 560 kilometers (348 miles) from the surface of the Earth
733895
From Glenn Kawesch:\nThe layer of atmosphere that lies about 15 to 50 kilometres above the Earth's surface. In the stratosphere, the temperature rises with increasing height, which is the opposite of the situation in the lower atmosphere. Ozone occurs in minute quantities throughout the full depth of the atmosphere, but its concentration peaks within the stratosphere at an altitude of about 35 kilometres. This is referred to as the ozone layer. There is little up-and-down air movement in the stratosphere, so the ozone layer stays in position.\n\nGlenn Kawesch

Antartica. This ozone hole over Antarctica - which exposes the countries in the Southern Hemisphere to dangerous levels of ultraviolet (UV) radiation, is mainly responsible for causing skin cancer. The ozone "hole" is not a physical hole but a reduction in concentrations of ozone high above the earth in the stratosphere. The ozone hole is defined geographically as the area wherein the total ozone amount is less than 220 Dobson Units.Only 10 or less of every million molecules of air are ozone. The majority of these ozone molecules resides in a layer between 10 and 40 kilometers (6 and 25 miles) above the Earth's surface in  the stratosphere. The ozone hole has steadily grown in size (up to 27 million sq. km.) both in length and depth ever since its discovery more than two decades ago. This phenomenon is mainly blamed on the indiscriminate use of Chloro-Floro-Carbons or CFC's mainly used in aerosal cans, air Conditioners and refregerators etc., whose concentration punches a hole in the ozone layer depleting it of ozone molecules which then allows harmful UV radiation to pass through causing cancer.

it is O3 and it protect the air from ultraviolet rays from the sun \nit is the outermost layer in the atmosphere \n \nor go on www.dictionary.com

troposphere: From the Greek word "tropos" meaning to turn or mix. The troposphere is the lowest layer of the atmosphere starting at the surface going up to between 7 km at the poles and 17 km at the equator with some variation due to weather factors. The troposphere has a great deal of vertical mixing due to solar heating at the surface. This heating warms air masses, which then rise to release latent heat as sensible heat that further buoys the air mass. This process continues until all water vapor is removed. In the troposphere, on average, temperature decreases with height due to expansive cooling. \n\nstratosphere: from that 7–17 km range to about 50 km, temperature increasing with height. \n\nmesosphere: from about 50 km to the range of 80 km to 85 km, temperature decreasing with height. \n\nthermosphere: from 80–85 km to 640+ km, temperature increasing with height. \n\nThe boundaries between these regions are named the tropopause, stratopause, and mesopause.\n\nAtmospheric regions are also named in other ways:\n\nionosphere – the region containing ions: approximately the mesosphere and thermosphere up to 550 km. \n\nexosphere – above the ionosphere, where the atmosphere thins out into space. This is the last major atmosphere. (“Exo” means “outside” in Greek.) \n\nmagnetosphere – the region where the Earth's magnetic field interacts with the solar wind from the Sun. It extends for tens of thousands of kilometers, with a long tail away from the Sun. \n\nozone layer – or ozonosphere, approximately 10 - 50 km, where stratospheric ozone is found. Note that even within this region, ozone is a minor constituent by volume. \n\nupper atmosphere – the region of the atmosphere above the mesopause. \n\nVan Allen radiation belts – regions where particles from the Sun become concentrated.

The ozone layer is thining through incresed pollutio by planes brought about by a peak in flyers, green house emissions, increased industrial pollution, forest degradation. all these allow more UV light penetration into earth and will continue to increase unless we stop polluting the environement.:(

stratosphere\nit's not ozone if you are talking about a layer, ozone is O3 not nessecarily a layer. i think you want to look for a specific type of scattering but i don't remeber which \n\none probably find it on wikiepdia.

The true fucnction of the ozone layer for one. I left you a source below. \n\nAlso the first deep space probes were sent out into the solar system during the 70's. Try to google "Mariner space probe" or "Voyager space probe".

Do you mean layers of the atmosphere that must be passed through on the way to space?\n\nFrom the ground up:\ntroposphere\nstratosphere\nmesosphere\nionosphere

When you say sky you must mean atmosphere. It divides into:\n\ntroposphere: The troposphere is the lowest layer of the atmosphere starting at the surface going up to between 7 km at the poles and 17 km at the equator with some variation due to weather factors.\n\nstratosphere: from that 7–17 km range to about 50 km, temperature increasing with height. \n\nmesosphere: from about 50 km to the range of 80 km to 85 km, temperature decreasing with height. \n\nthermosphere: from 80–85 km to 640+ km\n\nexosphere: from 640 to 900 km - space.\n\nSo you can say the sky is am least 640 and at most 900 high.

Ozone layer had undergone massive depletion due to natural and man-made causes. It had areas greatly decreased that made it to the point that there is already a "hole" or there is a certain area that no longer contain the ozone layer.\n\nThere are various factors  influencing  the ozone concentrations: >>Stratospheric sulfate aerosols mainly from  large explosive volcanoes greatly affect the ozone layers.\n>>Stratospheric winds  which bring about changes of the tropical winds in the lower stratosphere move ozone from one area to another.\n>>Greenhouse gases which might heat the planet and alter weather patterns affecting  the magnitude of the stratospheric winds.\n>>Sunspot cycle which is largely affected by unusual solar activity, solar storms and large solar flares which highly affect the ozone creation by solar UV radiation.\n>>Stratospheric chlorine, coming mostly from man-made halocarbons.\n\nWith all factors affecting the ozone creation, and movements and all that supports its depletion, ozone layer had lowered its  amount or its concentration which can cause the risk of harmful ultraviolet exposures. In simple term, the ozone layer had undergone thinning of its layer which some area already resulted to have holes. Anything that had thinned severely can breakdown anytime - that also applies to the ozone layer.♥

The ozone hole over the poles is a seasonal effect. Ozone depletion of the lower stratosphere due to chlorine containing gases takes place at all latitudes.\n\nIn the presence of UV light, these gases dissociate, releasing chlorine atoms, which then go on to catalyze ozone destruction. The Cl-catalyzed ozone depletion can take place in the gas phase, but it is dramatically enhanced in the presence of polar stratospheric clouds (PSCs). These clouds are composed of ice and nitric acid and form in extreme cold: over the poles in winter.\n\nThe PSC form particles which provide surfaces for the ozone desctruction reactions to take place. The PSC act as a catalysator and therefore the ozone depletion is largest in spring, when the clouds are still abundant and the sunlight is bright enough to drive the chemical reactions.
