[5] Stratospheric temperatures also vary within the stratosphere as the seasons change, reaching particularly low temperatures in the polar night (winter). No tracking or performance measurement cookies were served with this page. 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. 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. [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. We live in one layer, called the troposphere, where the clouds and most of the water vapor reside. Temperature decreases with height throughout the mesosphere. 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! The biosphere extends from the deepest root systems of trees, to the dark environments of ocean trenches, to lush rain forests, high mountaintops, and transition zones like this one, where ocean and terrestrial ecosystems meet. The bottom of the stratosphere is around 10 km (6.2 miles or about 33,000 feet) above the ground at middle latitudes. The air in the stratosphere is extremely thin, which makes it impossible to breathe at this level. Layers of the atmosphere: troposphere, stratosphere, mesosphere .

Some of these waves and tides carry energy from the troposphere upward into the stratosphere, others convey energy from the stratosphere up into the mesosphere. The stratosphere is a layer of Earths atmosphere. The troposphere, the lowest layer, is right below the stratosphere. As the altitude increases, the atmosphere diminishes which is the reason why the air pressure in the exosphere is shallow. Just above that is the stratosphere, the area of the atmosphere where passenger airplanes and weather balloons fly. Convection is the process whereby warm air rises and cooler air descends. Unlike the stratosphere, temperatures once again grow colder as you rise up through the mesosphere. The stratosphere accounts for approximately 24% of the earth's total atmosphere. Stratospheric warming of the polar vortex results in its weakening. As you might imagine, the "air" in the exosphere is very, very, very thin, making this layer even more space-like than the thermosphere. However, it is made up out of five different layers: The troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Earth's Atmospheric Layers | NASA 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. UCAR/Randy Russell 40 Unbelievable But True Troposphere Facts | Kidadl At Home Show All Free Coloring Pages Free Dot to Dot Printables Free Printable Stencils Funnies Trivia Birthdays Books Creative, Arts & Crafts On November 29, 1973, a Rppell's vulture (Gyps rueppelli) was ingested into a jet engine 11,278m (37,000ft) above the Ivory Coast. The thermosphere extends from about 90 km to 500 kmand 1,000 km above our planet. 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. Above the stratosphere lies the mesosphere, thermosphere, and exosphere. As a result, the air in the stratosphere is about 1000 times thinner in the stratosphere than at sea level in the troposphere. "Strat" means layer. Because of this, jet aircraft and weather balloons reach their maximum operational altitudes within the stratosphere. The layer made of layers Above the troposphere and below the mesosphere, we have 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. 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. In this region, the temperature increases with height. PSCs appear in the lower stratosphere near the poles in winter. Composed of mostly nitrogen and oxygen, the stratosphere also contains the ozone layer. There is very little water vapor in this layer of the atmosphere, so clouds are a rare occurrence. This layer of our atmosphere has its own set of layers. 33. It is the reason why the sky appears blue. Meteors burn up in the coldest layer, the mesosphere. The stratosphere contains approximately 19% of the earth's total atmospheric gases. The greenhouse gases increase the effect making the earths surface to be warmer than usual. We live in the troposphere, which is the layer of the atmosphere closest to earth. [6] Winds in the stratosphere can far exceed those in the troposphere, reaching near 60m/s (220km/h; 130mph) in the Southern polar vortex. To unlock this lesson you must be a Study.com Member. While common in the troposphere, very little convection takes place in the stratosphere. 16. 2023 TheFactFile.Org. The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high. Life as we know it wouldnt be possible without this layer of protection. 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. Overall, the attenuation of solar UV at wavelengths that damage DNA by the ozone layer allows life to exist on the surface of the planet outside of the ocean. 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. It is the only atmospheric layer where temperature inversion takes place. Certain birds can fly to this altitude, including cranes, swans, and vultures. As you rise through the troposphere, the temperature decreases to around -60 degrees Fahrenheit. Scientists have been warning people for many years about the damage we are doing to the ozone layer. A rare type of electrical discharge, somewhat akin to lightning, occurs in the stratosphere. There are forms of biological bacteria living in the stratosphere. Interesting Facts About Mercury. 23. 110 lessons. OH is formed by the reaction of electrically excited oxygen atoms produced by ozone photolysis, with water vapor. Because of this temperature stratification, there is little convection and mixing in the stratosphere, so the layers of air there are quite stable. Ozone is important for ensuring that just the right amount of ultraviolet radiation reaches the earth. The atmospheric gases must retain the heat in the sun rays and reflect them to the earth to keep it warm. The temperatures in the ozone belt are higher than in the troposphere since the ozone absorbs the ultraviolet rays. The stratosphere also contains the ozone layer, which absorbs harmful ultraviolet radiation as it enters our atmosphere from the sun. The stratosphere is where youll find the very important ozone layer. Due to the lack of vertical convection in the stratosphere, materials that get into the stratosphere can stay there for long times. Enrolling in a course lets you earn progress by passing quizzes and exams. In the 1900s, Hungarian physicist Theodore von Krmn determined the boundary to be around 50 miles up, or roughly 80 kilometers above sea level. The HO2 radical produced by the reaction of OH with O3 is recycled to OH by reaction with oxygen atoms or ozone. Rocket launches inject exhaust gases into the stratosphere, producing uncertain consequences. This border is known as the Karman line. Such is the case for ozone-destroying chemicals called CFCs (chlorofluorocarbons). The atmosphere is dense near the surface of the Earth and protects life on the planet Earth. Earth is a great planet to live on because it has a wonderful atmosphere around it. . Air density in this layer gradually decreases as you go higher. The image above illustrates the layers of Earth's atmosphere and their approximate distances from the Earth's surface. 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. The particles in the exosphere do not behave like gases. What are the characteristics of the five layers of the atmosphere? A.A. Scaife, J.R. Knight, G.K. Vallis, C.K. It changes sometimes unpredictably That's almost as wide as Earth itself. Exosphere widely contains particles of helium and hydrogen. Hare, J.R. Knight. But its not the same everywhere. Earths atmosphere has six different layers. However, temperature increases with altitude in the stratosphere, which is opposite from the troposphere. Moving upward from ground level, these layers are called the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. 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. The coldest temperatures in Earth's atmosphere, about -90 C (-130 F), are found near the top of this layer. 13. The first is due to the reaction of hydroxyl radicals (OH) with ozone. 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). In 1985, they observed a hole in the ozone layer above the Antarctic. 12 chapters | The particles in this layer are electrically charged, and when they hit each other, aurora australis can be observed. As harmful UV rays from the sun become absorbed in the ozone layer, this layer heats up. - 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? Facts About The Mesosphere - What It Is And Its Defining Characteristics 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. Dr. Rachel Tustin has a PhD in Education focusing on Educational Technology, a Masters in English, and a BS in Marine Science. This breaking is much more pronounced in the winter hemisphere where this region is called the surf zone. Most meteors burn up in the mesosphere. Paul J. Crutzen, Mario J. Molina and F. Sherwood Rowland were awarded the Nobel Prize in Chemistry in 1995 for their work describing the formation and decomposition of stratospheric ozone.[9]. 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. Ionosphere plays a vital role in radio signals broadcast on the earths surface. 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. The mesosphere is a layer of Earth's atmosphere. The atmosphere is a layer of gases retained by gravity on the earth. Stated another way, it allows the airliner to fly faster while maintaining lift equal to the weight of the plane. To learn more about each layer of the atmosphere, click the images below. One wild characteristic of the stratosphere is a phenomenon that occurs, which is known as blue jets. Close to the tropopause, temperatures start at approximately -51 Celsius (-60 Fahrenheit) and continue to rise until reaching the stratopause, where temperatures reach -15 Celsius (5 Fahrenheit). What's in the Atmosphere? It starts to glow, and the rocks begin to fly off. The stratosphere extends from from 4 -12 miles (6-20 km) above the Earth's surface to around 31 miles (50 km). That trend of rising temperatures with altitude means that air in the stratosphere lacks the turbulence and updrafts of the troposphere beneath. . As the ozone layer absorbs UV radiation, it causes the temperature in this layer to increase. Aurora is also referred to as polar light. Ozone molecules in this layer absorb high-energy ultraviolet (UV) light from the Sun, converting the UV energy into heat. Be grateful! Heat is produced in the process of the formation of Ozone, and this heat is responsible for . #1. It acts as a giant sponge and absorbs the vast majority of the sun's dangerous Ultraviolet Light. The word 'stratosphere' is derived from the word 'strato' meaning layer, and 'sphere' which is earth's shape. Temperature increases with height until the estimated top of the thermosphere at 500 km. 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. 2011 UCAR with portions adapted from Windows to the Universe ( 2009 NESTA). Earths atmosphere has six layers: the troposphere, the stratosphere, the mesosphere, the thermosphere, the ionosphere, and the exosphere. Sunlight is reflected in every direction by the gases present in the atmosphere. Commercial airliners typically cruise at altitudes of 912km (30,00039,000ft) which is in the lower reaches of the stratosphere in temperate latitudes. This diagram shows some of the features of the stratosphere. However, just above that is an equally important layer called the stratosphere. Facts About the Stratosphere Tower | USA Today As mentioned in the introduction, certain birds such as cranes, swans, and vultures can fly at this altitude. Mercury has water ice and organics. The increase of temperature with altitude is a result of the absorption of the Sun's ultraviolet (UV) radiation by the ozone layer. The atmosphere is one of four spheres of the earth, which include the atmosphere, the hydrosphere, the biosphere, and the lithosphere. Certain birds will even fly in the stratosphere, including swans, cranes, and vultures! 7. This includes its location, what it is composed of, the temperature range, and its density. Because of this, few clouds are found in this layer and almost all clouds occur in the lower, more humid troposphere. The water exists in the form of vapor and invisible to plain eyes. 8. It is located just above the troposphere, which is the first layer of the atmosphere closest to the ground. The temperatures at the different atmospheric layers differ depending on solar radiation, humidity, and altitude. This is also where you'll find low Earth orbit satellites. Like the other atmospheric layers, it does not have a fixed height but starts at an altitude of approximately 10 km(6 miles), extending up to a height of roughly 50 km(30 miles). Certain swans, cranes, and vultures can fly in the lower stratosphere. 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. Once you leave the stratosphere, and enter the mesosphere, the temperature dramatically decreases until plummeting to around -184 degrees Fahrenheit. Commercial passenger jets fly in the lower stratosphere, partly because this less-turbulent layer provides a smoother ride. The atmosphere comprises five layers: troposphere, stratosphere, mesosphere, thermosphere and exosphere. 31. 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. 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. For years, CFCs - a chemical used in aerosols - were transported the stratosphere via convection and became trapped there. What's in the Atmosphere? | NASA Climate Kids Its about 6,200 miles (10,000 kilometers) thick. Its upper edge has maximum ozone concentration, referred to as the ozone belt. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. 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. Stratosphere | Encyclopedia.com 18. The stratosphere is the second layer of the Earth's atmosphere, and lies approximately 10km to 50km above the Earth's surface. This includes the troposphere, mesosphere, thermosphere, exosphere, and stratosphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet. [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. 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. The stratosphere is the second layer of the Earth's atmosphere, laying just above the troposphere and below the mesosphere. At the top of the stratosphere, the density of the air is close to zero. All Rights Reserved. In the stratosphere - 'strato' means layer and sphere is the shape of the earth. Any opinions, findings and conclusions or recommendations expressed in this material do not necessarily reflect the views of the National Science Foundation. As previously mentioned, the stratosphere is one of the five layers that make up the Earth's atmosphere. Learn about the stratosphere, including the stratosphere's definition and importance. These are generated when cold atmospheric air blends with the hot, humid exhaust. The shiny blue marble continues to fascinate us since the time we began walking across its surfaces. They are a combination of supercooled water and nitric acid that develop at very low temperatures. Although humans would not be able to survive in the stratosphere due to thin air and frigid temperatures, there is life that can and does survive there. 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]. Autumn Skies Online Pty Ltd is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high (5 to 9 miles). Write CSS OR LESS and hit save. 25. Ice clouds form in this layer which is visible when lighted from beneath during sunset. As you go up, it becomes colder. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. [20], Some bird species have been reported to fly at the upper levels of the troposphere. What are 3 interesting facts about Mercury? These distances vary slightly due to elevation changes on the Earth. The presence of moisture in the atmosphere is At an altitude of 100 km above sea level, a border represents the separation between the atmosphere and outer space. Stratopause is the connection between the mesosphere and stratosphere. Above the stratosphere is the mesosphere. Planes and jets will sometimes. The layer of very rare air above the mesosphere is called the thermosphere. The atmospheric balance is jeopardized by human activities that cause global warming, greenhouse effect, ozone belt destruction, air contamination, and acid rains. Although the sun and other planets have magnetospheres, the earths magnetosphere is the strongest one of all the rocky planets. Thats almost as wide as Earth itself. It contains 80% of the atmospheric weight, making it the densest layer. Without the stratosphere, life on Earth would be very different or non-existent, as the shielding of the sun's radiation is important for known Earth life. It is enough to cover the entire earths surface with 1 cm of rain. As it absorbs the UV light, it absorbs energy. It is the highest layer. The stratosphere is actually crucial to allowing us to live on earth, because within the stratosphere you will find the ozone layer. Finally, chlorofluorocarbon molecules are photolysed in the stratosphere releasing chlorine atoms that react with ozone giving ClO and O2. 3 It borders the stratosphere below through a thin transitional space called the stratopause. The top of the stratosphere occurs at an altitude of 50 km (31 miles). I would definitely recommend Study.com to my colleagues. The stratosphere is the second layer of the atmosphere, which is composed of a total of five layers. Thats the opposite of how the layers work in the troposphere, where we live. The stratosphere ends where it transitions to the mesosphere, around 50 kilometers above the earth. It extends above the tropopause to an altitude of 50 km above the earth. The stratosphere is a layer of Earth's atmosphere. All air entering the stratosphere must pass through the tropopause, the temperature minimum that divides the troposphere and stratosphere. It is seen in high latitude areas as shimmering curtains of lights that are visible at night. 21. The stratosphere can be as deep 20 miles or as shallow as 5.5 miles. Stratospheric circulation is a predominantly wave-driven circulation in that the tropical upwelling is induced by the wave force by the westward propagating Rossby waves, in a phenomenon called Rossby-wave pumping. 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. That means that to get to outer space, you have to be really far from Earth. 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. The waves and tides influence the flows of air in the stratosphere and can also cause regional heating of this layer of the atmosphere. This site is owned and operated by Autumn Skies Online Pty Ltd, a limited liability company headquartered in Somerset West, South Africa. As a result, air circulation is not as prevalent in this layer of the atmosphere, making it difficult for some gasses to escape. Due to the high speed of the meteor, it generates a lot of heat resulting from high friction between the particles and the meteor. 17. (The fuel consumption depends on the drag, which is related to the lift by the lift-to-drag ratio.) The exosphere gradually fades away into the realm of interplanetary space. The ozone layer is a layer of gas within the stratosphere that protects the Earth's surface from harmful ultraviolet sun rays. 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. Around the poles, it actually begins at around 7 kilometers, whereas around the equator it can be as high as 20 kilometers. Troposphere - The lowest level of our atmosphere is called the Troposphere. It borders the mesosphere above through a thin transitional space called the stratopause. Air density is the lowest, and its temperature can increase up to 1500 degrees Celsius. The next higher layer above the stratosphere is the mesosphere. Various types of waves and tides in the atmosphere influence the stratosphere. https://en.wikipedia.org/w/index.php?title=Stratosphere&oldid=1140010063, This page was last edited on 18 February 2023, at 00:23. The thermosphere is home to the International Space Station as it orbits Earth. It helps in propagation of the radio waves used in telecommunication. It keeps us warm, it gives us oxygen to breathe, and its where our weather happens. The ionosphere stretches roughly 50 to 400 miles above Earth's surface, right at the edge of space. As a meteor begins to enter this layer, it rapidly bumps into mesosphere particles and scrapes against them. This was based on temperature profiles from mostly unmanned and a few manned instrumented balloons. Current map of global winds and temperatures at the 10 hPa level. Above the troposphere and below the mesosphere, we have the stratosphere. Facts About the Atmosphere - Overview, Benefits and Its Layers The lower boundary of the stratosphere can be as high as 20 km (12 miles or 65,000 feet) near the equator and as low as 7 km (4 miles or 23,000 feet) at the poles in winter. The stratosphere also has an increasing temperature with increasing altitude, which is different than what happens in the troposphere. Radicals produced from the homolytically split oxygen molecules combine with molecular oxygen to form ozone. Polar Stratospheric Clouds develop in this layer near the poles at an altitude of 15 - 25 kilometers. The stratosphere begins at around 10 kilometers above the surface of the earth. Weather balloons also rise up to this level of the atmosphere to collect data without interference of storm clouds.
