This article focus on the stratosphere, Earth's second layer. Write CSS OR LESS and hit save. Current map of global winds and temperatures at the 10 hPa level. The stratosphere is a region of intense interactions among radiative, dynamical, and chemical processes, in which the horizontal mixing of gaseous components proceeds much more rapidly than does vertical mixing. 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 stratosphere is very cold, ranging in temperatures from negative 68F to negative 5F. The exosphere gradually fades away into the realm of interplanetary space. Thermosphere | NASA Space Place - NASA Science for Kids 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. Stratopause is the connection between the mesosphere and stratosphere. 2 It extends from a height of approximately 65 km (40 miles) to 85 km (53 miles) above the Earth's surface. Atmosphere Atmosphere and Its Layers Such is the case for ozone-destroying chemicals called CFCs (chlorofluorocarbons). However, it is made up out of five different layers: 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. Stratosphere. Certain birds can fly to this altitude, including cranes, swans, and vultures. The stratosphere is composed primarily of nitrogen and oxygen. There is very little water vapor in this layer of the atmosphere, so clouds are a rare occurrence. [21] Bar-headed geese (Anser indicus) sometimes migrate over Mount Everest, whose summit is 8,848m (29,029ft). Enrolling in a course lets you earn progress by passing quizzes and exams. The presence of moisture in the atmosphere is It is the only atmospheric layer where temperature inversion occurs and the region where the ozone layer is situated. Radicals produced from the homolytically split oxygen molecules combine with molecular oxygen to form ozone. These free-moving elements continuously escape into space due to ballistic trajectories. Most of the clouds form in the troposphere, just below the stratosphere. 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. [7] Molecular oxygen absorbs high energy sunlight in the UV-C region, at wavelengths shorter than about 240nm. 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. This UV radiation is important for the production of vitamin D in humans, but too much can destroy tissue. The stratosphere is where youll find the very important ozone layer. To unlock this lesson you must be a Study.com Member. Between the troposphere and stratosphere is the tropopause border that demarcates the beginning of the temperature inversion. The stratosphere is the second layer of the atmosphere, in between the troposphere and the mesosphere. A rare type of electrical discharge, somewhat akin to lightning, occurs in the stratosphere. Layers of the Atmosphere | National Oceanic and Atmospheric Administration The atmospheric gases must retain the heat in the sun rays and reflect them to the earth to keep it warm. Its upper edge has maximum ozone concentration, referred to as the ozone belt. It surrounds our planet, keeps us warm, gives us oxygen to breathe, and it is where our weather happens. What's in the Atmosphere? | NASA Climate Kids As you might imagine, the "air" in the exosphere is very, very, very thin, making this layer even more space-like than the thermosphere. Since blue light has short wavelengths, it gets reflected more compared to other colors. The temperature increases to about negative {eq}5 {/eq} F in the stratosphere. As a result, it tends to trap any and all gases that enter this region of the atmosphere. Stratosphere | NASA Space Place - NASA Science for Kids 33. 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 atmosphere gradually changes as the climate and weather change. Once you leave the stratosphere, and enter the mesosphere, the temperature dramatically decreases until plummeting to around -184 degrees Fahrenheit. 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. Starting at ground level, it extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level. Gases and dust from volcanic eruptions often meet the same fate, remaining trapped in the stratosphere for months or even longer. The stratosphere is the second layer in the Earth's atmosphere. Luckily the situation has improved since the ban of chlorofluorocarbon. 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. Three Highest Thrill Rides in the World. At an altitude of 100 km above sea level, a border represents the separation between the atmosphere and outer space. The atmosphere consists of five distinct layers, with the stratosphere being the second, situated just above the troposphere. It contains 80% of the atmospheric weight, making it the densest layer. . 21. The air in the mesosphere is far too thin to breathe (the air pressure at the bottom of the layer is well below 1% of the pressure at sea level and continues dropping as you go higher). 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. The height of the bottom of the stratosphere varies with latitude and with the seasons. (Learn more about Nacreous or Polar Stratospheric Clouds in this article.). The atmosphere comprises five layers: troposphere, stratosphere, mesosphere, thermosphere and exosphere. The ionosphere is not a distinct layer like the others mentioned above. 5. PSCs are also called nacreous clouds. Stratosphere | NASA Space Place - NASA Science for Kids I would definitely recommend Study.com to my colleagues. The layer made of layers Above the troposphere and below the mesosphere, we have the stratosphere. Mercury has an atmosphere that changes with its distance to the Sun. As a meteor begins to enter this layer, it rapidly bumps into mesosphere particles and scrapes against them. Terms & Conditions 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 bottom of the stratosphere is around 10 km (6.2 miles or about 33,000 feet) above the ground at middle latitudes. It has increased the number of respiratory conditions such as asthma. 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. Clouds form due to convection, which is uncommon in the stratosphere. . Its magnetic field goes up to 60,000 km into space. They have been observed by airline pilots and the international space station. The rides, which are called The Big Shot, Insanity and X-Scream, are equally terrifying and exciting. 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. This was based on temperature profiles from mostly unmanned and a few manned instrumented balloons. The atmosphere surrounds our planet like the peel of an orange. These troposphere facts are going to make you see the air around you in a very different light and help you learn more about how we live and breathe. Facts About The Exosphere: The Outermost Layer Of The Atmosphere. 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. Facts About the Stratosphere Tower | USA Today 110 lessons. 9. Ionization takes place in the ionosphere caused by the suns radiation. [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. The exosphere is the very edge of our atmosphere. There are some species of birds capable of flying in the stratosphere. There are forms of biological bacteria living in the stratosphere. Earth's atmosphere is a jacket of gases that surrounds our planet. Biosphere forms part of the troposphere where life exists. Earth's atmosphere has a series of layers, each with its own specific traits. This layer of our atmosphere has its own set of layers. This is the opposite of what happens in the troposphere, the layer of the atmosphere closest to Earth. 17. The site owner may have set restrictions that prevent you from accessing the site. The stratosphere ends where it transitions to the mesosphere, around 50 kilometers above the earth. Cred: NASA's Scientific Visualization Studio 3. 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. Exosphere | NASA Space Place - NASA Science for Kids This allows the stratosphere to have an increasing temperature with altitude. Just like the troposphere, its depth varies with latitude. The latter value is about halfway to the Moon! 35. The layer of very rare air above the mesosphere is called the thermosphere. 5. Thislayerseparates the rest of the atmosphere from outer space. 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 oxygen atom product combines with atmospheric molecular oxygen to reform O3, releasing heat. The mesosphere is directly above the stratosphere and below the thermosphere. They are much similar to warm breath during cold weather. As this article clearly illustrated, the stratosphere has a crucial role to play in maintaining the atmosphere and all life in it. 3090 Center Green Drive, Boulder, CO 80301, Air pressure drops, and temperatures get colder, as you climb higher in the troposphere, ACOM | Atmospheric Chemistry Observations & Modeling, CISL | Computational & Information Systems, EdEC | Education, Engagement & Early-Career Development, Government Relations & External Engagement. The stratosphere has many defining features that make it a unique part of the atmosphere. 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. It is called stratosphere because it is stratified in temperature, with warmer layers higher up and cooler layers farther down. To learn more about each layer of the atmosphere, click the images below. They are a combination of supercooled water and nitric acid that develop at very low temperatures. Earth's atmosphere is similar to a jacket for our planet. [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 . stratosphere The atmospheric layer above the troposphere, which extends on average from about 10 to 50 km above the Earth's surface. 2. Ozone is a gas made up of three oxygen atoms (O 3). In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. Strat means layer. This layer is 22 miles (35 kilometers) thick. The particles in this layer are electrically charged, and when they hit each other, aurora australis can be observed. The Stratosphere | Center for Science Education 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. In the 1900s, Hungarian physicist Theodore von Krmn determined the boundary to be around 50 miles up, or roughly 80 kilometers above sea level. That trend of rising temperatures with altitude means that air in the stratosphere lacks the turbulence and updrafts of the troposphere beneath. Heat is produced in the process of the formation of Ozone, and this heat is responsible for . As it absorbs the UV light, it absorbs energy. 40 Unbelievable But True Troposphere Facts | Kidadl Strat means layer. 25. In many ways, the thermosphere is more like outer space than a part of the atmosphere. 7. 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. Convection is when gasses cool down as they rise, allowing them to condense onto air particles and form clouds. However, this feature allows commercial airliners to fly in the lower stratosphere while traveling faster and save fuel. Planting trees is one of the efforts that people have done to try to minimize damage and to help rebuild the damaged ozone layer. This layer of our atmosphere has its own set of layers. Almost all weather is in this region. Atmosphere facts: ninety-nine percent of the gases that compose the atmosphere are located below a height of 32 km (20 miles). Weather balloons also rise up to this level of the atmosphere to collect data without interference of storm clouds. It surrounds our planet, keeps us warm, gives us oxygen to breathe, and it is where our weather happens. No tracking or performance measurement cookies were served with this page. Air density in this layer gradually decreases as you go higher. 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]. The timescale of this rapid mixing is much smaller than the much slower timescales of upwelling in the tropics and downwelling in the extratropics. As you go up, it becomes colder. Above the troposphere and below the mesosphere, we have the stratosphere. There is no clear-cut upper boundary where the exosphere finally fades away into space. The Brief Overview. It extends above the tropopause to an altitude of 50 km above the earth. This is due to the temperature changes within the stratosphere. As a result, air circulation is not as prevalent in this layer of the atmosphere, making it difficult for some gasses to escape. "Strat" means layer. The stratosphere also has an increasing temperature with increasing altitude, which is different than what happens in the troposphere. Most clouds appear here, mainly because 99% of the water vapor in the atmosphere is found in the troposphere. The Stratosphere also has three thrill rides at the top. During northern hemispheric winters, sudden stratospheric warmings, caused by the absorption of Rossby waves in the stratosphere, can be observed in approximately half of winters when easterly winds develop in the stratosphere. Ozone protects life on Earth from the Sun's ultraviolet (UV) radiation. 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. Unlike the troposphere however it is colder closer to the earth and warmer as it gets closer to the mesosphere. Composition of the Earth's atmosphere. Earths atmosphere is similar to a jacket for our planet. The main gases are nitrogen and oxygen, which make up 99% of the atmosphere. As a result, the air in the stratosphere is about 1000 times thinner in the stratosphere than at sea level in the troposphere. Ozone molecules in this layer absorb high-energy ultraviolet (UV) light from the Sun, converting the UV energy into heat. 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. It is possible to send research balloons into the stratosphere. There are little to no clouds in the stratosphere from the lack of convection. - 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? This jacket of gases does a lot for us. 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. UCAR/Randy Russell It is like a giant magnet and retains high-energy particles, thereby protecting the earth. Any opinions, findings and conclusions or recommendations expressed in this material do not necessarily reflect the views of the National Science Foundation. The following list highlights the characteristics and facts of the stratosphere in more detail. The exosphere is really, really big. Just like the troposphere, its depth varies with latitude. (The ozone layer is too large a topic for this article, but you can read more about it in the following post.). Stratosphere - Definition, Functions & Characteristics with Videos - BYJUS 10 Things to Know About the Ionosphere - NASA Solar System Exploration Earth is a great planet to live on because it has a wonderful atmosphere around it. Meteors burn up in the coldest layer, the mesosphere. 20. For years, CFCs - a chemical used in aerosols - were transported the stratosphere via convection and became trapped there. . It is made up of 78% nitrogen and 21% oxygen. 6. The ozone layer absorbs the majority of these rays, shielding life from harmful radiation. The stratosphere extends from from 4 -12 miles (6-20 km) above the Earth's surface to around 31 miles (50 km). It is seen in high latitude areas as shimmering curtains of lights that are visible at night. Unlike the troposphere, the stratosphere actually gets warmer the higher you go! Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. The stratosphere accounts for approximately 24% of the earth's total atmosphere. Thats the opposite of how the layers work in the troposphere, where we live. There are a few other atmospheric layers as well -- you can take a look at a diagram of these below. 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. Due to the lack of vertical convection in the stratosphere, materials that get into the stratosphere can stay there for long times. As you rise through the troposphere, the temperature decreases to around -60 degrees Fahrenheit. Facts About Stratosphere - GKToday As altitude increases, air density in the layers of the atmosphere decrease. 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. The stratosphere is located above the troposphere and below the mesosphere. Bacterial life survives in the stratosphere, making it a part of the biosphere. They result from ionized particles from the sun striking the upper atmosphere above the poles. 29. The troposphere, the lowest layer, is right below the stratosphere. Due to the high speed of the meteor, it generates a lot of heat resulting from high friction between the particles and the meteor. The next higher layer above the stratosphere is the mesosphere. The stratosphere is a layer of Earth's atmosphere. 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. 77 Exciting Facts about the Atmosphere - LovePsychologys This results in an increase in temperature from about -76 degrees Fahrenheit to around 5 degrees Fahrenheit. The composition of the atmosphere of each celestial body is different. It is located just above the troposphere, which is the first layer of the atmosphere closest to the ground. What Causes Air Pollution? Rocket launches inject exhaust gases into the stratosphere, producing uncertain consequences. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. 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. Skin cancer frequency is increasing due to the thinning of the ozone layer. This is exactly the opposite of the behavior in the troposphere in which we live, where temperatures drop with increasing altitude. 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. It has a very important job: to protect us from harmful energy from the Sun, called radiation. The air has a very low density that you get into the interplanetary space without a manifest limit. Without it, the earths surface would be so cold that living here would not be possible. ], 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. All Rights Reserved. [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. Brewer-Dobson Circulation occurs in the stratosphere. copyright 2003-2023 Study.com. You might have seen planes leaving white condensation trails. Thats almost as wide as Earth itself. These distances vary slightly due to elevation changes on the Earth.

While the stratosphere is dry, additional water vapor is produced in situ by the photochemical oxidation of methane (CH4). Facts about the Earth's Atmosphere - Odyssey Magazine This is the opposite of what happens in the troposphere, where an increasing altitude yields a decrease in temperature. 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. 28. It sets it apart from the other atmospheric layers by temperature rising instead of dropping as altitude increases, a process called temperature inversion. 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. 32. 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. Facts About The Stratosphere: What It Is And Its Defining Characteristics The stratosphere the atmosphere's second layer, and is located right above the troposphere and right below the mesosphere. Planes and jets will sometimes. Stratosphere | Encyclopedia.com Above the troposphere and below the mesosphere, we have the stratosphere. The stratosphere is one of five layers of the earth's atmosphere. - 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. The infamous ozone layer is found within the stratosphere. The ozone layer is a layer of gas within the stratosphere that protects the Earth's surface from harmful ultraviolet sun rays. As the altitude increases, the atmosphere diminishes which is the reason why the air pressure in the exosphere is shallow. . 31. N.Butchart, A.A. Scaife, J. Austin, S.H.E. 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. She currently works as a physicist assistant at a cancer treatment center. measured by the humidity of the air. Because of this temperature stratification, there is little convection and mixing in the stratosphere, so the layers of air there are quite stable. Endeavoring to achieve professional growth through ongoing development of skills and using new and accepted methods of . It changes sometimes unpredictably Privacy Policy The stratosphere is the second layer of the atmosphere. The contrails usually become thin at low humidity and high altitudes. 4 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. The mesosphere is a layer of Earth's atmosphere. Convection is the process whereby warm air rises and cooler air descends. The other four layers include the troposphere, mesosphere, thermosphere, and exosphere. It is the reason why the sky appears blue. But there are no mountains high enough to reach the stratosphere, so you dont have to worry about that. However, the air in this layer is so thin that it would feel freezing cold to us! Mercury has water ice and organics. The ozone layer is situated within this layer. The exosphere gradually fades away into the realm of interplanetary space. It is the only layer of the atmosphere where temperature inversion occurs. 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. 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. So, what does the stratosphere do? The temperatures in the ozone belt are higher than in the troposphere since the ozone absorbs the ultraviolet rays. A single chlorine atom can destroy more than a hundred thousand ozone molecules. The ozone layer lies in the stratosphere, which absorb the majority of harmful UV radiation from the sun.
