Above the stratosphere is the mesosphere. A Division ofAutumn Skies Online (Pty) Ltd Disclaimer There are no storms or turbulence here to mix up the air, so cold, heavy air is at the bottom and warm, light air is at the top. Clouds form due to convection, which is uncommon in the stratosphere.

The stratosphere is located above the troposphere and below the mesosphere. 28. The next higher layer above the stratosphere is the mesosphere. It extends above the tropopause to an altitude of 50 km above the earth. Atmosphere facts: ninety-nine percent of the gases that compose the atmosphere are located below a height of 32 km (20 miles). It is enough to cover the entire earths surface with 1 cm of rain. Meteors burn up in the coldest layer, the mesosphere. However, the distance of 100 kms from the earths surface is what is considered generally as an imaginary boundary. Why Is Carbon Important? Ice clouds form in this layer which is visible when lighted from beneath during sunset. The main gases are nitrogen and oxygen, which make up 99% of the atmosphere. There are little to no clouds in the stratosphere from the lack of convection. Other gases such as carbon dioxide, argon, helium, and neon occupy the remaining portion. Its magnetic field goes up to 60,000 km into space. As a meteor begins to enter this layer, it rapidly bumps into mesosphere particles and scrapes against them. Above the troposphere and below the mesosphere, we have the stratosphere. If you do your calculations, each water vapor particle spends approximately nine days in the atmosphere. Clouds rarely form in the stratosphere for this reason as well, as the air is very dry. As mentioned in the introduction, certain birds such as cranes, swans, and vultures can fly at this altitude. Just above that is the stratosphere, the area of the atmosphere where passenger airplanes and weather balloons fly. Its about 6,200 miles (10,000 kilometers) thick. The temperatures at the different atmospheric layers differ depending on solar radiation, humidity, and altitude. The greenhouse gases increase the effect making the earths surface to be warmer than usual. 21. It comprises the magnetosphere and ionosphere. In the lower atmosphere (the troposphere) near the Earth's surface, ozone is created by chemical reactions between air pollutants . The jet stream flows near the border between the troposphere and the stratosphere. Troposphere - The lowest level of our atmosphere is called the Troposphere. Along with the neutral upper atmosphere, the ionosphere forms the boundary between Earth's lower atmosphere where we live and breathe and the vacuum of space. 5. The chlorine atoms are recycled when ClO reacts with O in the upper stratosphere, or when ClO reacts with itself in the chemistry of the Antarctic ozone hole. It is the reason why the sky appears blue. It is the only layer of the atmosphere where temperature inversion occurs. All other trademarks and copyrights are the property of their respective owners. The destruction of the ozone layer lets an enormous amount of ultraviolet rays reach the earth, which leads to skin cancer and cataracts in humans and animals alike. Air pressure drops, and temperatures get colder, as you climb higher in the troposphere. [21] Bar-headed geese (Anser indicus) sometimes migrate over Mount Everest, whose summit is 8,848m (29,029ft). The atmospheric balance is jeopardized by human activities that cause global warming, greenhouse effect, ozone belt destruction, air contamination, and acid rains. The water ice appears younger than we would expect. They result from ionized particles from the sun striking the upper atmosphere above the poles. The atmosphere surrounds our planet like the peel of an orange. Layers of the atmosphere: troposphere, stratosphere, mesosphere and thermosphere. These gases are chemically inert, although some can react with various chemicals: carbon monoxide, sulfur dioxide, methane, ammonia, ozone, and water vapor. Mercury has an atmosphere that changes with its distance to the Sun. This diagram shows some of the features of the stratosphere. Also known as Nacreous Clouds, these unique clouds develop near the poles at an altitude of 15 - 25 kilometers (9 - 15 miles) during the winter months. The stratosphere is the second layer of the Earth's atmosphere, laying just above the troposphere and below the mesosphere. This list does not contain all the data available about the stratosphere but highlights the key facts and characteristics of this layer. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. We now know that there are additional ozone loss mechanisms and that these mechanisms are catalytic meaning that a small amount of the catalyst can destroy a great number of ozone molecules. Because of this, the top of the thermosphere can be found anywhere between 500 and 1,000 km (311 to 621 miles) above the ground. However, this feature allows commercial airliners to fly in the lower stratosphere while traveling faster and save fuel. Providing an environment conducive to good instruction and motivation in which there is an atmosphere of self-motivation and self-discipline in the areas of personal development, character, and academic integrity. There is no clear-cut upper boundary where the exosphere finally fades away into space. This breaking is much more pronounced in the winter hemisphere where this region is called the surf zone. The HO2 radical produced by the reaction of OH with O3 is recycled to OH by reaction with oxygen atoms or ozone. This site is owned and operated by Autumn Skies Online Pty Ltd, a limited liability company headquartered in Somerset West, South Africa. In the stratosphere - 'strato' means layer and sphere is the shape of the earth. Air density in this layer gradually decreases as you go higher. This material is based upon work supported by the National Center for Atmospheric Research, a major facility sponsored by the National Science Foundation and managed by the University Corporation for Atmospheric Research. This was based on temperature profiles from mostly unmanned and a few manned instrumented balloons. There are no storms or turbulence here to mix up the air, so cold, heavy air is at the bottom and warm, light air is at the top. They go from the ground all the way to outer space. . The electrically charged atoms and molecules that are formed in this way are called ions, giving the ionosphere its name and endowing this region with some special properties. 32. 18. As a result, air circulation is not as prevalent in this layer of the atmosphere, making it difficult for some gasses to escape. Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. Ozone protects life on Earth from the Sun's ultraviolet (UV) radiation. Another large-scale feature that significantly influences stratospheric circulation is the breaking planetary waves[15] resulting in intense quasi-horizontal mixing in the midlatitudes. The atmosphere is about 500 km thick, with a mix of more than ten different gases. Damage to the ozone layer of the stratosphere occurs naturally when volcanic gases and dust reach the stratosphere, but people have been contributing to this as well with the use of aerosol's containing CFCs. It surrounds the globe and protects it by absorbing the infrared rays from the sun. UCAR/Randy Russell There are forms of biological bacteria living in the stratosphere. Although the sun and other planets have magnetospheres, the earths magnetosphere is the strongest one of all the rocky planets. 13. 11. Thislayerseparates the rest of the atmosphere from outer space. 6. Life as we know it wouldnt be possible without this layer of protection. The holes in the ozone layer have been recorded above the Antarctica seasonally, as well as in other parts of the world. 25. The atmosphere has nearly 37.5 million billion gallons of water at any given time. In fact it is not easy to distinguish between space and not space because of the fact that the Earths atmosphere doesnt simply vanish; rather, it gradually becomes thinner and thinner over about 600 miles. Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. Earth's atmosphere is similar to a jacket for our planet. Planes that are low on fuel also fly at this altitude because they can cover more distance than in the troposphere while using less fuel and encountering less turbulence. 15. It also consists of a layer known as the ozone layer, a blanket of ozone that absorbs harmful ultraviolet (UV) rays from the sun. It surrounds our planet, keeps us warm, gives us oxygen to breathe, and it is where our weather happens. Planting trees is one of the efforts that people have done to try to minimize damage and to help rebuild the damaged ozone layer. Earths atmosphere is similar to a jacket for our planet. Folland. Unlike the troposphere, it contains little water vapor so there are no clouds in this layer of the atmosphere. But there are no mountains high enough to reach the stratosphere, so you dont have to worry about that. Approximately 90 percent of the atmosphere's ozone occurs in the stratosphere, the region extending from 10-18 km (6-11 miles) to approximately 50 km (about 30 miles) above Earth's surface. Since blue light has short wavelengths, it gets reflected more compared to other colors. This is also where you'll find low Earth orbit satellites. The stratosphere is one of the 5 layers of the atmosphere, situated above the troposphere and below the mesosphere at an altitude of 10 km (6 miles), extending to 50 km (30 miles). The air has a very low density that you get into the interplanetary space without a manifest limit. We are not permitting internet traffic to Byjus website from countries within European Union at this time. Air density is the lowest, and its temperature can increase up to 1500 degrees Celsius. The atmosphere has nearly 37.5 million billion gallons of water at any given time. The mesosphere is directly above the stratosphere and below the thermosphere. The presence of moisture in the atmosphere is Stratosphere is the second layer. The Earth's atmosphere is a mixture of several gases. Acidic rains destroy plants and animals, and if it reaches rivers and lakes, it destroys all the aquatic life. The stratosphere is very dry air and contains little water vapor. That means that to get to outer space, you have to be really far from Earth. Finally, chlorofluorocarbon molecules are photolysed in the stratosphere releasing chlorine atoms that react with ozone giving ClO and O2. Instead, the ionosphere is a series of regions in parts of the mesosphere and thermosphere where high-energy radiation from the Sun has knocked electrons loose from their parent atoms and molecules. This diagram shows some of the features of the stratosphere. The importance of the stratosphere is highlighted by the presence of the ozone layer, without which no life on Earth will be possible. You might have seen planes leaving white condensation trails. The stratosphere is actually crucial to allowing us to live on earth, because within the stratosphere you will find the ozone layer. Unlike the troposphere however it is colder closer to the earth and warmer as it gets closer to the mesosphere. The thinning is most pronounced in the polar regions, especially over Antarctica. Planes and jets will sometimes choose to fly in the stratosphere, where there are no clouds or weather that can affect the ride. Above the troposphere and below the mesosphere, we have the stratosphere. Blue jets are an extremely rare form of lightning or electrical discharge from clouds in the troposphere. Earths atmosphere has six different layers. Although on average the stratosphere begins at about 7 miles up from the earth's surface, it can range from 5 miles at the earth's poles, to 6-8 miles at moderate latitudes, to 11 miles at the equator. It means temperatures rise as altitude increases in this region, unlike the other four layers, which are characterized by a drop in temperature as altitude increases. While common in the troposphere, very little convection takes place in the stratosphere. Brewer-Dobson Circulation occurs in the stratosphere. The stratosphere is a layer of Earths atmosphere. This layer of our atmosphere has its own set of layers. 30. 5. - Facts, Layers & Population, The Changing Earth: Volcanoes, Weathering & Deposition, The Four Spheres of Earth: Geosphere, Hydrosphere, Biosphere, and Atmosphere, Interactions of Earth's Spheres: Purpose and Examples, Ionosphere: Definition, Facts, Temperature & Layers, Understanding Plate Tectonics: Tutoring Solution, Understanding Earthquakes: Tutoring Solution, Understanding Volcanoes: Tutoring Solution, Rock Deformation & Mountain Building: Tutoring Solution, Shaping the Earth's Surface: Tutoring Solution, Energy in the Earth System: Tutoring Solution, Earth's Energy Resources: Tutoring Solution, Earth's Material Resources: Tutoring Solution, Earth Science Investigation & Experimentation: Tutoring Solution, Environmental Science 101: Environment and Humanity, UExcel Pathophysiology: Study Guide & Test Prep, Stratosphere Lesson for Kids: Definition & Facts, What is Alginic Acid? The exosphere is the very edge of our atmosphere. A.A. Scaife, J.R. Knight, G.K. Vallis, C.K. "Strat" means layer. 9. This includes its location, what it is composed of, the temperature range, and its density. The thermosphere extends from about 90 km to 500 kmand 1,000 km above our planet. Ozone, which is actually a molecule made up of three oxygen atoms linked together by covalent bonds, absorbs harmful ultraviolet radiation that enters the Earth's atmosphere as part of sunlight. - This is the second layer of the atmosphere from the surface of the earth, and lies between the troposphere and the mesosphere. Sunlight is reflected in every direction by the gases present in the atmosphere. 14. The stratosphere is the second layer in the Earth's atmosphere. Enrolling in a course lets you earn progress by passing quizzes and exams. Composed of mostly nitrogen and oxygen, the stratosphere also contains the ozone layer. [2][3] The stratosphere is an atmospheric layer composed of stratified temperature layers, with the warm layers of air high in the sky and the cool layers of air in the low sky, close to the planetary surface of the Earth. If you look up at the sky, either on a clear day or a starry night, it probably wouldn't occur to you that you are looking through layers. Earth's atmosphere is a jacket of gases that surrounds our planet. Write CSS OR LESS and hit save. This breaking is caused due to a highly non-linear interaction between the vertically propagating planetary waves and the isolated high potential vorticity region known as the polar vortex. This is the opposite of what happens in the troposphere, the layer of the atmosphere closest to Earth. 3090 Center Green Drive, Boulder, CO 80301, Virtual Ballooning to Explore the Atmosphere, ACOM | Atmospheric Chemistry Observations & Modeling, CISL | Computational & Information Systems, EdEC | Education, Engagement & Early-Career Development, Government Relations & External Engagement. The stratosphere is situated just above the troposphere, with a thin layer of air called the tropopause separating the two layers. Its like a teacher waved a magic wand and did the work for me.

The particles in this layer are electrically charged, and when they hit each other, aurora australis can be observed. But there are no mountains high enough to reach the stratosphere, so you dont have to worry about that. The next higher layer above the stratosphere is the mesosphere. Air circulation within the stratosphere is dominated by the Brewer-Dobson Circulation, which is a single-celled air movement that stretches from the Poles to the Equator. This UV radiation is important for the production of vitamin D in humans, but too much can destroy tissue. Convection is the process whereby warm air rises and cooler air descends. Learn about the stratosphere, including the stratosphere's definition and importance. These "blue jets" appear above thunderstorms, and extend from the bottom of the stratosphere up to altitudes of 40 or 50 km (25 to 31 miles). Some researchers and even students have sent helium balloons with cameras to record the stratosphere. Cred: NASA's Scientific Visualization Studio 3. The ozone layer is situated within this layer. Most turbulence at this altitude is caused by variations in the jet stream and other local wind shears, although areas of significant convective activity (thunderstorms) in the troposphere below may produce turbulence as a result of convective overshoot. The atmosphere comprises five layers: troposphere, stratosphere, mesosphere, thermosphere and exosphere. An interesting feature of stratospheric circulation is the quasi-biennial oscillation (QBO) in the tropical latitudes, which is driven by gravity waves that are convectively generated in the troposphere.
