She earned her bachelor's in Physics and Astronomy from the University of North Carolina at Asheville. Create an account to start this course today. It is the only atmospheric layer where temperature inversion occurs and the region where the ozone layer is situated. Scientists have been warning people for many years about the damage we are doing to the ozone layer. This layer of our atmosphere has its own set of layers. Strat means layer. The stratosphere is one of five layers of the atmosphere. Earth's atmosphere is similar to a jacket for our planet. The stratosphere is a very interesting layer in Earth's atmosphere, as there are many fun stratosphere facts outside of its primary characteristics that make it unique. The stratosphere is situated just above the troposphere, with a thin layer of air called the tropopause separating the two layers. 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. Most clouds appear here, mainly because 99% of the water vapor in the atmosphere is found in the troposphere. As a result of the EUs General Data Protection Regulation (GDPR). 34. Convection is when gasses cool down as they rise, allowing them to condense onto air particles and form clouds. The exosphere gradually fades away into the realm of interplanetary space. Its concentration in the atmosphere naturally fluctuates depending on seasons and latitudes, but it was . Ozone layer lies about 19-32 km over the earths surface. The waves and tides influence the flows of air in the stratosphere and can also cause regional heating of this layer of the atmosphere. The stratosphere ( / strtsfr, - to -/) is the second layer of the atmosphere of the Earth, located above the troposphere and below the mesosphere. Variations in the amount of energy coming from the Sun exert a powerful influence on both the height of the top of this layer and the temperature within it. The stratosphere extends from the tropopause at about 10 to 17 km (about 6 to 11 miles) altitude to its upper boundary (the stratopause) at . Air pressure drops, and temperatures get colder, as you climb higher in the troposphere. It is the highest layer. 5. Temperature decreases with height throughout the mesosphere. The exosphere gradually fades away into the realm of interplanetary space. These distances vary slightly due to elevation changes on the Earth. To unlock this lesson you must be a Study.com Member. Biosphere forms part of the troposphere where life exists. It extends above the tropopause to an altitude of 50 km above the earth. Various types of waves and tides in the atmosphere influence the stratosphere. The ionosphere stretches roughly 50 to 400 miles above Earth's surface, right at the edge of space. As this article clearly illustrated, the stratosphere has a crucial role to play in maintaining the atmosphere and all life in it. Within the stratosphere temperatures increase with altitude (see temperature inversion); the top of the stratosphere has a temperature of about 270 K (3C or 26.6F).[8]. Earth's atmosphere has a series of layers, each with its own specific traits. Its upper edge has maximum ozone concentration, referred to as the ozone belt. These gases are chemically inert, although some can react with various chemicals: carbon monoxide, sulfur dioxide, methane, ammonia, ozone, and water vapor. They are a combination of supercooled water and nitric acid that develop at very low temperatures. As it absorbs the UV light, it absorbs energy. This is also where you'll find low Earth orbit satellites. . The temperatures at the different atmospheric layers differ depending on solar radiation, humidity, and altitude. Acid rains form when nitrogen oxide or Sulphur dioxide combines with water vapor in the atmosphere. While the stratosphere is dry, additional water vapor is produced in situ by the photochemical oxidation of methane (CH4). Ozone is important for ensuring that just the right amount of ultraviolet radiation reaches the earth. The atmosphere is a layer of gases retained by gravity on the earth. Facts About The Stratosphere: What It Is And Its Defining Characteristics These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure. The stratosphere is where youll find the very important ozone layer. It has different layers with different qualities. Interestingly, the most significant portion of the atmosphere is located within twelve kilometers of the earths surface. Without the stratosphere, life on Earth would be much different, if not non-existent. Ozone layer | Description, Importance, & Facts | Britannica 33. The atmospheric balance is jeopardized by human activities that cause global warming, greenhouse effect, ozone belt destruction, air contamination, and acid rains. 12. Stratosphere is the second layer. 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. 11. Of all the atmospheric layers, this is the most closest to the Earth. The water exists in the form of vapor and invisible to plain eyes. The importance of the stratosphere is highlighted by the presence of the ozone layer, without which no life on Earth will be possible. [6] Winds in the stratosphere can far exceed those in the troposphere, reaching near 60m/s (220km/h; 130mph) in the Southern polar vortex. This creates a smoother ride for passengers, as there are few clouds or weather in the stratosphere. Life as we know it wouldnt be possible without this layer of protection. They are much similar to warm breath during cold weather. Earth's atmosphere has six layers: the troposphere, the stratosphere, the mesosphere, the thermosphere, the ionosphere, and the exosphere. Facts About The Exosphere: The Outermost Layer Of The Atmosphere. Weather balloons also rise up to this level of the atmosphere to collect data without interference of storm clouds. The stratosphere is the second layer of the atmosphere, in between the troposphere and the mesosphere. Thats the opposite of how the layers work in the troposphere, where we live. The layer of very rare air above the mesosphere is called the thermosphere. Around the poles, it actually begins at around 7 kilometers, whereas around the equator it can be as high as 20 kilometers. ], 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. 29. 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). Meteorological phenomena are limited to the troposphere since they result from the earths rotation and suns radiation on the atmosphere. Mesosphere lies between 50-85 km above sea level. The atmosphere surrounds our planet like the peel of an orange. Air pollution causes the demolition of the ozone belt, and without it, the earth would be exposed to the deadly ultraviolet rays in the sun. OH is formed by the reaction of electrically excited oxygen atoms produced by ozone photolysis, with water vapor. Facts About The Mesosphere - What It Is And Its Defining Characteristics 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 aurora, the Northern Lights and Southern Lights, occur in the thermosphere. The stratosphere is very dry air and contains little water vapor. 18. The stratosphere protects Earth life from extremely harmful UV rays from the sun. 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. From space, the earth is seen as a blue halo. Brewer-Dobson Circulation occurs in the stratosphere. Certain birds can fly to this altitude, including cranes, swans, and vultures. The stratosphere also contains the ozone layer, which absorbs harmful ultraviolet radiation as it enters our atmosphere from the sun. Skin cancer frequency is increasing due to the thinning of the ozone layer. However, it is made up out of five different layers: The troposphere, stratosphere, mesosphere, thermosphere, and exosphere. (The ozone layer is too large a topic for this article, but you can read more about it in the following post.).

The next higher layer above the stratosphere is the mesosphere. The mesosphere is the third layer of the atmosphere (above the troposphere and stratosphere.) The composition of the atmosphere of each celestial body is different. The thermosphere extends from about 90 km to 500 kmand 1,000 km above our planet. As previously mentioned, the stratosphere is one of the five layers that make up the Earth's atmosphere. Composition of the Earth's atmosphere. Temperature decreases with height throughout the mesosphere. https://en.wikipedia.org/w/index.php?title=Stratosphere&oldid=1140010063, This page was last edited on 18 February 2023, at 00:23. Ice clouds form in this layer which is visible when lighted from beneath during sunset. Though the atmosphere may appear uniform to the naked eye, it is actually similar to a layer cake. In addition, solar proton events can significantly affect ozone levels via radiolysis with the subsequent formation of OH. It reaches up to the mesosphere, with another thin layer of air called the stratopause separating them. 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. Ozone protects life on Earth from the Sun's ultraviolet (UV) radiation. 26. The infamous ozone layer is found within the stratosphere. Stratosphere | atmospheric region | Britannica The stratosphere can be as deep 20 miles or as shallow as 5.5 miles. 5. It is the reason why the sky appears blue. Facts About the Atmosphere - Overview, Benefits and Its Layers The layer made of layers. The image above illustrates the layers of Earth's atmosphere and their approximate distances from the Earth's surface. The stratosphere begins at around 10 kilometers above the surface of the earth. The stratosphere is one of five layers of the earth's atmosphere. The overall circulation of the stratosphere is termed as Brewer-Dobson circulation, which is a single-celled circulation, spanning from the tropics up to the poles, consisting of the tropical upwelling of air from the tropical troposphere and the extra-tropical downwelling of air. The rapid photolysis and reformation of ozone heat the stratosphere, resulting in a temperature inversion. Such is the case for ozone-destroying chemicals called CFCs (chlorofluorocarbons). It extends upward to a height of about 85 km (53 miles) above our planet. Air density is the lowest, and its temperature can increase up to 1500 degrees Celsius. The air density is also very low, making it less turbulent to travel through. 25. The atmosphere is one of four spheres of the earth, which include the atmosphere, the hydrosphere, the biosphere, and the lithosphere. The QBO induces a secondary circulation that is important for the global stratospheric transport of tracers, such as ozone[14] or water vapor. 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. He discovered this atmospheric layer by sending a weather balloon up and noticing that the temperature changes differently than it does in the troposphere. 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. The latter value is about halfway to the Moon! Sunlight is reflected in every direction by the gases present in the atmosphere. Ozone (O3) photolysis produces O and O2. We take a closer look at the stratosphere and its defining characteristics. Different definitions place the top of the exosphere somewhere between 100,000 km (62,000 miles) and 190,000 km (120,000 miles) above the surface of Earth. This diagram shows some of the features of the stratosphere. The temperatures decrease by 6.5 degrees Celsius each kilometer, reaching -55 degrees Celsius at the top limit of the troposphere, commonly known as the tropopause. No tracking or performance measurement cookies were served with this page. The ozone layer is within the stratosphere, which protect the Earth from harmful radiation emitted by the sun. The stratosphere was discovered in 1900 by French meteorologist Lon Teisserenc de Bort. This is how certain gases become trapped in the stratosphere, like CFC's and ozone. 14. It is called stratosphere because it is stratified in temperature, with warmer layers higher up and cooler layers farther down. In many ways, the thermosphere is more like outer space than a part of the atmosphere. Autumn Skies Online Pty Ltd also participates in affiliate programs with Clickbank, CJ, ShareASale, and other sites. Its upper edge has maximum ozone concentration, referred to as the ozone belt. Like an onion, the Earth's atmosphere is composed of many layers. Stratosphere | NASA Space Place - NASA Science for Kids 6. 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 wind, which is the air current, is generated when the hot air rises and gets replaced by colder air. The coldest temperatures in Earth's atmosphere, about -90 C (-130 F), are found near the top of this layer. Just like the troposphere, its depth varies with latitude. As harmful UV rays from the sun become absorbed in the ozone layer, this layer heats up. Atmosphere Layers: Facts About the Atmosphere Layers 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). Despite Mercury's weak magnetic field, it behaves similarly to Earth's. 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. 10 Things to Know About the Ionosphere - NASA Solar System Exploration The stratosphere is abundant in ozone, a type of oxygen molecule that absorbs the sun's ultraviolet radiation and uses it to heat this layer in the atmosphere. Cred: NASA's Scientific Visualization Studio 3. The timescale of this rapid mixing is much smaller than the much slower timescales of upwelling in the tropics and downwelling in the extratropics. This is the opposite of what happens in the troposphere, the layer of the atmosphere closest to Earth. The mesosphere is directly above the stratosphere and below the thermosphere. This diagram shows some of the features of the stratosphere. The more humid the atmosphere is, the thicker the contrails will be. Since blue light has short wavelengths, it gets reflected more compared to other colors. It is made up of 78% nitrogen and 21% oxygen. The atmosphere has nearly 37.5 million billion gallons of water at any given time. This layer of our atmosphere has its own set of layers. Most airplanes or jets travel in the lower part of the stratosphere. This layer is 22 miles (35 kilometers) thick. It is easy & understandable to view our atmosphere as a continuous layer of air. - This is the second layer of the atmosphere from the surface of the earth, and lies between the troposphere and the mesosphere. 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 air in the stratosphere is extremely thin, which makes it impossible to breathe at this level. The stratosphere has many defining features that make it a unique part of the atmosphere. The stratosphere is the second layer of the atmosphere, which is composed of a total of five layers. Ionization takes place in the ionosphere caused by the suns radiation. PSCs appear in the lower stratosphere near the poles in winter. Thus it means layer which surrounds the earth. [19] In 2001, dust was collected at a height of 41 kilometres in a high-altitude balloon experiment and was found to contain bacterial material when examined later in the laboratory. The lower portion of the stratosphere is nearly isothermal (a layer of constant temperature), whereas temperatures in its upper levels increase with altitude. Exosphere widely contains particles of helium and hydrogen. 16. A.A. Scaife, J.R. Knight, G.K. Vallis, C.K. Near the equator, the lower edge of the stratosphere is as high as 20km (66,000ft; 12mi), at midlatitudes around 10km (33,000ft; 6.2mi), and at the poles about 7km (23,000ft; 4.3mi). As altitude increases, air density in the layers of the atmosphere decrease. Planes and jets will sometimes. What are the characteristics of stratosphere? The troposphere, the lowest layer, is right below the stratosphere. The ozone layer is situated within this layer. The atmospheric gases must retain the heat in the sun rays and reflect them to the earth to keep it warm. The ozone layer is very important, as it protects life on Earth from the majority of the UV rays emitted from the sun. The mesosphere is a layer of Earth's atmosphere. Strat means layer. The atmosphere is dense near the surface of the Earth and protects life on the planet Earth. You might have seen planes leaving white condensation trails. Be grateful! In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. Instead, clouds condense in the troposphere. The troposphere, the lowest layer, is right below the stratosphere. The contrails usually become thin at low humidity and high altitudes. As you might imagine, the "air" in the exosphere is very, very, very thin, making this layer even more space-like than the thermosphere. Rainbow Facts: What Is A Rainbow And How Does It Occur? To learn more about each layer of the atmosphere, click the images below. The coldest temperatures are found in the mesopause. 3 It borders the stratosphere below through a thin transitional space called the stratopause. The ozone layer, which absorbs and scatters the . Facts About Stratosphere Published: April 3, 2016 The stratosphere is the second major layer of Earth's atmosphere, just above the troposphere, and below the mesosphere. Three Highest Thrill Rides in the World. Atmosphere Atmosphere and Its Layers This article focus on the stratosphere, Earth's second layer. The rising air is literally freeze dried; the stratosphere is a very dry place. 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. 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. Theexosphereis really, really big. Layers of the atmosphere: troposphere, stratosphere, mesosphere . The atmosphere comprises five layers: troposphere, stratosphere, mesosphere, thermosphere and exosphere. As a result, it tends to trap any and all gases that enter this region of the atmosphere. UCAR/Randy Russell Ozone layer facts and information - Environment The stratosphere is located above the troposphere and below the mesosphere. 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. 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. 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. "Strat" means layer. Privacy Policy Ozone depletion is a major environmental problem because it increases the amount of ultraviolet (UV . Above the stratosphere lies the mesosphere, thermosphere, and exosphere. It contains 80% of the atmospheric weight, making it the densest layer. Geomagnetic solar storms caused by solar flares or solar winds can disrupt activities in the ionosphere, causing difficulty in transmitting radio signals and global positioning system signals. For this reason, humans would not be able to survive at this altitude without being inside of a plane, rocket, or some type of enclosed environment where air density can be regulated. There are a few other atmospheric layers as well -- you can take a look at a diagram of these below. Terms & Conditions This jacket of gases does a lot for us. The lower boundary of the stratosphere is called the tropopause; the upper boundary is called the stratopause. Never miss out again when another interesting and helpful article is released and stay updated, while also receiving helpful tips & information by simplyclicking on this link .Until next time, keep your eye on the weather! Although some experts consider the thermosphere to be the uppermost layer of our atmosphere, others consider the exosphere to be the actual "final frontier" of Earth's gaseous envelope. This layer is 22 miles (35 kilometers) thick. It occurs naturally in small (trace) amounts in the upper atmosphere (the stratosphere). Folland. Composed of mostly nitrogen and oxygen, the stratosphere also contains the ozone layer. The atmosphere has nearly 37.5 million billion gallons of water at any given time. 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 comprises the magnetosphere and ionosphere. It extends above the tropopause to an altitude of 50 km above the earth. [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. 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. Convection is when gases cool as they rise, allowing them to condense on air molecules which form clouds. Other gases such as carbon dioxide, argon, helium, and neon occupy the remaining portion. These events often precede unusual winter weather [16] and may even be responsible for the cold European winters of the 1960s.[17]. 3. 12 chapters | The holes in the ozone layer have been recorded above the Antarctica seasonally, as well as in other parts of the world. The amount of water vapour in the stratosphere is very low, and because of this there are no clouds in the stratosphere. Above the troposphere and below the mesosphere, we have the stratosphere. This layer holds 19 percent of the atmosphere's gases but very little water vapor. Stratosphere - The Stratosphere makes up around 25% of the total of Earth's atmosphere, and is home to more than 90% of our Earth's O-Zone layer. What are the characteristics of the five layers of the atmosphere? An increase of altitude in the troposphere makes temperatures decrease, which is why it is much colder on the top of a mountain than on sea level. Certain bird species like the common crane, whooper swan, and the Rppel's griffon vulture are capable of flying in the lower stratosphere. The atmosphere gradually changes as the climate and weather change. Endeavoring to achieve professional growth through ongoing development of skills and using new and accepted methods of . 10. (The lack of weather activity in the stratosphere also allows aircraft to avoid adverse weather conditions by flying in the lower stratosphere above the weather.). 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. Because of this temperature stratification, there is little convection and mixing in the stratosphere, so the layers of air there are quite stable. It contains the ozone layer and is between the troposphere, the first layer of the atmosphere, and the mesosphere, the third layer of the atmosphere. The ozone layer absorbs the majority of these rays, shielding life from harmful radiation. However, this feature allows commercial airliners to fly in the lower stratosphere while traveling faster and save fuel. Earth is a great planet to live on because it has a wonderful atmosphere around it. The definition of the stratosphere is the second layer of the atmosphere, extending from about 6 miles to 30 miles, or 10km to 50km, above the Earth's surface. Interesting Facts About Mercury. This is just an estimate, however, as the lower and upper boundaries actually vary with the latitude of the earth. Air density in this layer gradually decreases as you go higher. "Strat" means layer. These are generated when cold atmospheric air blends with the hot, humid exhaust. Unlike the stratosphere, temperatures once again grow colder as you rise up through the mesosphere. The resultant breaking causes large-scale mixing of air and other trace gases throughout the midlatitude surf zone. 19. The stratosphere extends from from 4 -12 miles (6-20 km) above the Earth's surface to around 31 miles (50 km). It sets it apart from the other atmospheric layers by temperature rising instead of dropping as altitude increases, a process called temperature inversion.
