The burning of fossil fuels discharges carbon dioxide, while agricultural developments deposit a lot of methane and nitrogen oxides into the atmosphere. It is made up of 78% nitrogen and 21% oxygen. While the stratosphere is dry, additional water vapor is produced in situ by the photochemical oxidation of methane (CH4). If you were to climb a mountain in the stratosphere you would have to take off your warm clothes as you got closer to the top rather than putting them on like we usually do. 3 It borders the stratosphere below through a thin transitional space called the stratopause. - There are no clouds in the layer, and though . A good percentage of the earths population breathes contaminated air, primarily sulfur dioxide and carbon monoxide emitted by industrial factories. The stratosphere is a layer of Earth's atmosphere. There is very little water vapor in this layer of the atmosphere, so clouds are a rare occurrence. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun.

It is the only atmospheric layer where temperature inversion takes place. The atmosphere is a layer of gases retained by gravity on the earth. [11] This optimizes fuel efficiency, mostly due to the low temperatures encountered near the tropopause and low air density, reducing parasitic drag on the airframe. The stratosphere is the second layer of the Earth's atmosphere, and lies approximately 10km to 50km above the Earth's surface. The mesosphere is a layer of Earth's atmosphere. The layer made of layers. Ozone (O3) photolysis produces O and O2. The infamous ozone layer is found within the stratosphere. Nitrous oxide (N2O) is produced by biological activity at the surface and is oxidised to NO in the stratosphere; the so-called NOx radical cycles also deplete stratospheric ozone. stratosphere, layer of Earth's atmosphere lying between the troposphere and the mesosphere. Sydney Chapman gave a correct description of the source of stratospheric ozone and its ability to generate heat within the stratosphere;[citation needed] he also wrote that ozone may be destroyed by reacting with atomic oxygen, making two molecules of molecular oxygen. 77 Amazing, Interesting, and Exciting Facts about the Atmosphere It extends above the tropopause to an altitude of 50 km above the earth. If you are interested in the complete structure and make-up of the atmosphere,this articlecovers all five atmospheric layers and their relation to each other in more detail. The shiny blue marble continues to fascinate us since the time we began walking across its surfaces. Rocket launches inject exhaust gases into the stratosphere, producing uncertain consequences. It lies above the troposphere, the layer closest to Earth, and below the mesosphere. Thats the opposite of how the layers work in the troposphere, where we live. Autumn Skies Online Pty Ltd is compensated for referring traffic and business to these companies., The Earth's atmosphere consists of five layers. The ozone layer is a layer of gas within the stratosphere that protects the Earth's surface from harmful ultraviolet sun rays. Thats almost as wide as Earth itself. The troposphere is the lowest layer of our atmosphere. The Stratosphere also has three thrill rides at the top. It surrounds our planet, keeps us warm, gives us oxygen to breathe, and it is where our weather happens. The stratosphere also has an increasing temperature with increasing altitude, which is different than what happens in the troposphere. The stratosphere protects Earth life from extremely harmful UV rays from the sun. 2023 TheFactFile.Org. As it absorbs the UV light, it absorbs energy. Ozone layer (highest concentration of ozone in the atmosphere) The ozone layer is a thin layer of the stratosphere made of a gas called ozone. Meteorological phenomena are limited to the troposphere since they result from the earths rotation and suns radiation on the atmosphere. That's much thicker than the inner layers of the atmosphere, but not nearly as thick as the exosphere. Planes and jets will sometimes choose to fly in the stratosphere, where there are no clouds or weather that can affect the ride. The temperatures in the ozone belt are higher than in the troposphere since the ozone absorbs the ultraviolet rays. stratosphere: [noun] the part of the earth's atmosphere which extends from the top of the troposphere to about 30 miles (50 kilometers) above the surface and in which temperature increases gradually to about 32 F (0 C) and clouds rarely form. It surrounds our planet, keeps us warm, gives us oxygen to breathe, and it is where our weather happens. Sunlight is reflected in every direction by the gases present in the atmosphere. Layers of the atmosphere: troposphere, stratosphere, mesosphere and thermosphere. The exosphere is really, really big. The rides, which are called The Big Shot, Insanity and X-Scream, are equally terrifying and exciting. They are found at altitudes of 15 to 25 km (9.3 to 15.5 miles) and form only when temperatures at those heights dip below -78 C. They appear to help cause the formation of the infamous holes in the ozone layer by "encouraging" certain chemical reactions that destroy ozone. Ozone, an unusual type of oxygen molecule that is relatively abundant in the stratosphere, heats this layer as it absorbs energy from incoming ultraviolet radiation from the Sun. At the outer limit of the magnetic field is the magnetosphere. This diagram shows some of the features of the stratosphere. 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. - Structure, Solubility & Products, Arrow Pushing Mechanism in Organic Chemistry, Topicity in Stereochemistry: Relationships & Examples, Antarafacial & Suprafacial Relationships in Organic Chemistry, Working Scholars Bringing Tuition-Free College to the Community. As altitude increases, air density in the layers of the atmosphere decrease. The stratosphere the atmosphere's second layer, and is located right above the troposphere and right below the mesosphere. The mesosphere is directly above the stratosphere and below the thermosphere. A.A. Scaife, J.R. Knight, G.K. Vallis, C.K. A two-step reactive mechanism produces ozone in the stratosphere naturally. I would definitely recommend Study.com to my colleagues. What are the characteristics of the five layers of the atmosphere? 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 aurora, the Northern Lights and Southern Lights, occur in the thermosphere. One of the most surprising things about the stratosphere is not its characteristics but about what you find in this layer. Life as we know it wouldnt be possible without this layer of protection. [12] Eustace also broke the world records for vertical speed skydiving, reached with a peak velocity of 1,321km/h (822mph) and total freefall distance of 123,414ft (37,617m) lasting four minutes and 27 seconds.[13]. This breaking is much more pronounced in the winter hemisphere where this region is called the surf zone. PSCs are also called nacreous clouds. This layer separates the rest of the atmosphere from outer space. 90% of the ozone layer is found in the stratosphere's upper crust. Due to the high speed of the meteor, it generates a lot of heat resulting from high friction between the particles and the meteor. 29. 24. The coldest temperatures in Earth's atmosphere, about -90 C (-130 F), are found near the top of this layer. ], While looking up at the sky on a cloud-free day, one will see what looks like a continuous piece of[], The stratosphere is the second layer of the atmosphere, It extends from a height of approximately 10 km. This ozone layer is important for man's survival, and for the survival of life on earth, as it absorbs the UV radiation from the sun that would otherwise be deadly. This includes its location, what it is composed of, the temperature range, and its density. 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. [18] When the vortex is strong, it keeps the cold, high-pressure air masses contained in the Arctic; when the vortex weakens, air masses move equatorward, and results in rapid changes of weather in the mid latitudes. Due to the lack of vertical convection in the stratosphere, materials that get into the stratosphere can stay there for long times. 5. It also allows the airplane to stay above the turbulent weather of the troposphere. Solar ultraviolet radiation (sunlight) separates an oxygen molecule into two different oxygen atoms in the first step. The thermosphere is home to the International Space Station as it orbits Earth. Bacterial life survives in the stratosphere, making it a part of the biosphere. 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. PSCs appear in the lower stratosphere near the poles in winter. "Strat" means layer. Due to this, the stratosphere has very little convection, which causes chemicals derived from aerosols, known as CFC's, to become confined to the stratosphere. The rapid photolysis and reformation of ozone heat the stratosphere, resulting in a temperature inversion. This is also where you'll find low Earth orbit satellites. Because the temperature in the tropopause and lower stratosphere is largely constant with increasing altitude, very little convection and its resultant turbulence occurs there. To unlock this lesson you must be a Study.com Member. It is the only layer of the atmosphere where temperature inversion occurs. 23. The stratosphere is the second layer of the atmosphere, in between the troposphere and the mesosphere. While the troposphere is filled with a vast assortment of clouds thanks to a gas we know as water vapor, the stratosphere is a vast, clear blue sky. The stratosphere is the second layer of the atmosphere, which is composed of a total of five layers. 22. Earth is a great planet to live on because it has a wonderful atmosphere around it. Most meteors burn up in the mesosphere. Another large-scale feature that significantly influences stratospheric circulation is the breaking planetary waves[15] resulting in intense quasi-horizontal mixing in the midlatitudes. This UV radiation is important for the production of vitamin D in humans, but too much can destroy tissue. 2 It extends from a height of approximately 65 km (40 miles) to 85 km (53 miles) above the Earth's surface. Biosphere forms part of the troposphere where life exists. The atmosphere comprises five layers: troposphere, stratosphere, mesosphere, thermosphere and exosphere. The stratosphere is very dry air and contains little water vapor. There are little to no clouds in the stratosphere from the lack of convection. This creates a smoother ride for passengers, as there are few clouds or weather in the stratosphere. Ozone is important for ensuring that just the right amount of ultraviolet radiation reaches the earth. The oxygen atom product combines with atmospheric molecular oxygen to reform O3, releasing heat. Air pressure drops, and temperatures get colder, as you climb higher in the troposphere. [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. Of all the atmospheric layers, this is the most closest to the Earth. 26. It surrounds the globe and protects it by absorbing the infrared rays from the sun. Any opinions, findings and conclusions or recommendations expressed in this material do not necessarily reflect the views of the National Science Foundation. Stratosphere is the second layer. The stratosphere contains approximately 19% of the earth's total atmospheric gases. Create an account to start this course today. The stratosphere can be as deep 20 miles or as shallow as 5.5 miles. This decrease in temperature with altitude is what causes convection to occur in the troposphere. 31. Certain birds can fly to this altitude, including cranes, swans, and vultures. The top of the stratosphere occurs at an altitude of 50 km (31 miles). Composed of mostly nitrogen and oxygen, the stratosphere also contains the ozone layer. The stratosphere is a major stable layer whose base is marked by the tropopause, and where temperatures overall average approximately 60 C.Temperature in the lower stratosphere is isothermal but increases markedly in the upper part, to reach a maximum of . Above the stratosphere is the mesosphere. The presence of moisture in the atmosphere is The bottom of the stratosphere is around 10 km (6.2 miles or about 33,000 feet) above the ground at middle latitudes. The temperature increases to about negative {eq}5 {/eq} F in the stratosphere. Skin cancer frequency is increasing due to the thinning of the ozone layer. The stratosphere contains the ozone layer, which shields the Earth from harmful radiation emitted from the Sun. It not only examines what the stratosphere is but also looks at the characteristics or facts that define it. - This is the second layer of the atmosphere from the surface of the earth, and lies between the troposphere and the mesosphere. 18. Ice clouds form in this layer which is visible when lighted from beneath during sunset. Around the poles, it actually begins at around 7 kilometers, whereas around the equator it can be as high as 20 kilometers. 33. Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. The stratospheric air is extremely thin and dry since the vast majority of atmospheric gases (and weather activity) are limited to the troposphere. #1. The stratosphere is home to the ozone layer, which is a thin layer of concentrated ozone which plays an essential role in protecting the Earth from dangerous solar radiation. Planes fly in the stratosphere to avoid turbulence and fly longer distances using less fuel. Earth's atmosphere has a series of layers, each with its own specific traits. The stratosphere is located above the troposphere and below the mesosphere. This part of the atmosphere is the most dense. This jacket of gases does a lot for us. The Earth's atmosphere is a mixture of several gases. Earth's atmosphere is similar to a jacket for our planet. Facts About The Exosphere: The Outermost Layer Of The Atmosphere. It sets it apart from the other atmospheric layers by temperature rising instead of dropping as altitude increases, a process called temperature inversion. This layer of Earth's atmosphere is about 319 miles (513 kilometers) thick. The ozone layer is very important, as it protects life on Earth from the majority of the UV rays emitted from the sun. Air density is the lowest, and its temperature can increase up to 1500 degrees Celsius. Privacy Policy It is the second layer of the atmosphere as you go upward. Due to the characteristics of the stratosphere, it is a very important part of Earth's atmosphere. 19. That's the opposite of how the . Although it is situated above the upper reaches of conventional aircraft, scientists are still able to study it through the use of weather balloons, high-altitude aircraft, and also weather (sounding) rockets. Some researchers and even students have sent helium balloons with cameras to record the stratosphere. It is easy & understandable to view our atmosphere as a continuous layer of air. The thinning is most pronounced in the polar regions, especially over Antarctica. 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). The holes in the ozone layer have been recorded above the Antarctica seasonally, as well as in other parts of the world. The wind, which is the air current, is generated when the hot air rises and gets replaced by colder air. Because of this, jet aircraft and weather balloons reach their maximum operational altitudes within the stratosphere. 7. The stratosphere ends where it transitions to the mesosphere, around 50 kilometers above the earth. Interesting Facts About Mercury. These gases are chemically inert, although some can react with various chemicals: carbon monoxide, sulfur dioxide, methane, ammonia, ozone, and water vapor. Stated another way, it allows the airliner to fly faster while maintaining lift equal to the weight of the plane. This is just an estimate, however, as the lower and upper boundaries actually vary with the latitude of the earth. Airplanes fly in the stratosphere to avoid turbulence. Atmosphere facts: ninety-nine percent of the gases that compose the atmosphere are located below a height of 32 km (20 miles). All air entering the stratosphere must pass through the tropopause, the temperature minimum that divides the troposphere and stratosphere. On top of that, air samples from this altitude have shown that certain types of bacteria and microbes are present in the stratosphere, making it the closest to space and furthest from the Earth's surface that humans have found life naturally living. measured by the humidity of the air. 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. 21. However, this feature allows commercial airliners to fly in the lower stratosphere while traveling faster and save fuel. 34. Temperatures rise as one moves upward through the stratosphere. She earned her bachelor's in Physics and Astronomy from the University of North Carolina at Asheville. 1. 110 lessons. The height of the bottom of the stratosphere varies with latitude and with the seasons. Commercial airliners fly in the lower stratosphere to avoid the weather, travel faster, and save fuel. Discover fun facts about the stratosphere and stratosphere characteristics. This is exactly the opposite of the behavior in the troposphere in which we live, where temperatures drop with increasing altitude. The stratosphere is the second layer in the Earth's atmosphere. The stratosphere is one of five layers of the earth's atmosphere. 3. It is in the thermosphere that the space shuttle flew. The stratosphere (/strtsfr, -to-/) is the second layer of the atmosphere of the Earth, located above the troposphere and below the mesosphere. But there are no mountains high enough to reach the stratosphere, so you dont have to worry about that. It is also roughly 35 kilometers (22 miles) thick. Interestingly, the most significant portion of the atmosphere is located within twelve kilometers of the earths surface. Each year, this large amount of water is recycled about 40 times. Starting at ground level, it extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level. Most airplanes or jets travel in the lower part of the stratosphere. However, exceptionally energetic convection processes, such as volcanic eruption columns and overshooting tops in severe supercell thunderstorms, may carry convection into the stratosphere on a very local and temporary basis. 14. Large volcanic eruptions and major meteorite impacts can fling aerosol particles up into the stratosphere where they may linger for months or years, sometimes altering Earth's global climate.
