Around the poles, it actually begins at around 7 kilometers, whereas around the equator it can be as high as 20 kilometers. 30. It is called stratosphere because it is stratified in temperature, with warmer layers higher up and cooler layers farther down. The thinning is most pronounced in the polar regions, especially over Antarctica. The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high (5 to 9 miles). The coldest temperatures in Earth's atmosphere, about -90 C (-130 F), are found near the top of this layer. It has a very important job: to protect us from harmful energy from the Sun, called radiation. The stratosphere is very cold, ranging in temperatures from negative 68F to negative 5F. 9. The stratosphere also traps certain gasses known as CFC's, which are chemicals derived from aerosol. 7. It surrounds our planet, keeps us warm, gives us oxygen to breathe, and it is where our weather happens. Since the ozone layer absorbs UV rays from the sun, it heats up, which allows temperatures to increase as altitude increases. Earth's atmosphere has a series of layers, each with its own specific traits. copyright 2003-2023 Study.com. Stratospheric warming of the polar vortex results in its weakening. Though the atmosphere may appear uniform to the naked eye, it is actually similar to a layer cake. Other gases that make up the remaining 0.1 percent include trace amounts of carbon dioxide, methane, water vapour, and neon. 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. [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]. Stated another way, it allows the airliner to fly faster while maintaining lift equal to the weight of the plane. Here are 50 Interesting facts about the atmosphere that you probably didnt know. Air is roughly a thousand times thinner at the top of the stratosphere than it is at sea level. Providing an environment conducive to good instruction and motivation in which there is an atmosphere of self-motivation and self-discipline in the areas of personal development, character, and academic integrity. [5] Stratospheric temperatures also vary within the stratosphere as the seasons change, reaching particularly low temperatures in the polar night (winter). There are little to no clouds in the stratosphere from the lack of convection. The atmospheric gases must retain the heat in the sun rays and reflect them to the earth to keep it warm. All other trademarks and copyrights are the property of their respective owners. The stratosphere is one of five layers of the atmosphere. Most of the clouds form in the troposphere, just below the stratosphere. A good percentage of the earths population breathes contaminated air, primarily sulfur dioxide and carbon monoxide emitted by industrial factories. 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. The top of the stratosphere occurs at an altitude of 50 km (31 miles). As this article clearly illustrated, the stratosphere has a crucial role to play in maintaining the atmosphere and all life in it. Dr. Rachel Tustin has a PhD in Education focusing on Educational Technology, a Masters in English, and a BS in Marine Science. The atmosphere comprises five layers: troposphere, stratosphere, mesosphere, thermosphere and exosphere. Above the troposphere and below the mesosphere, we have the stratosphere. There are forms of biological bacteria living in the stratosphere. Its magnetic field goes up to 60,000 km into space. However, it is made up out of five different layers: The troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Ozone depletion is a major environmental problem because it increases the amount of ultraviolet (UV . 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. Composition of the Earth's atmosphere. It is in the thermosphere that the space shuttle flew. At an altitude of 100 km above sea level, a border represents the separation between the atmosphere and outer space. 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. [7] Molecular oxygen absorbs high energy sunlight in the UV-C region, at wavelengths shorter than about 240nm. Without it, the earths surface would be so cold that living here would not be possible. The oxygen atom product combines with atmospheric molecular oxygen to reform O3, releasing heat. The wind, which is the air current, is generated when the hot air rises and gets replaced by colder air. It changes sometimes unpredictably No tracking or performance measurement cookies were served with this page. Ozone is a gas made up of three oxygen atoms (O 3). Just like the troposphere, its depth varies with latitude. 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]. Biosphere forms part of the troposphere where life exists. The next higher layer above the stratosphere is the mesosphere. As a result, the air in the stratosphere is about 1000 times thinner in the stratosphere than at sea level in the troposphere. This jacket of gases does a lot for us. The mesosphere is directly above the stratosphere and below the thermosphere. . This is how certain gases become trapped in the stratosphere, like CFC's and ozone. Commercial airliners typically cruise at altitudes of 912km (30,00039,000ft) which is in the lower reaches of the stratosphere in temperate latitudes. The more humid the atmosphere is, the thicker the contrails will be. It surrounds the globe and protects it by absorbing the infrared rays from the sun. Enrolling in a course lets you earn progress by passing quizzes and exams. 32. It is the reason why the sky appears blue. The atmosphere is a layer of gases retained by gravity on the earth. However, the air in this layer is so thin that it would feel freezing cold to us! 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. 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. 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. Ozone protects life on Earth from the Sun's ultraviolet (UV) radiation. The ozone layer lies in the stratosphere, which absorb the majority of harmful UV radiation from the sun. Terms & Conditions 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). The atmosphere has nearly 37.5 million billion gallons of water at any given time. 2 It extends from a height of approximately 65 km (40 miles) to 85 km (53 miles) above the Earth's surface. The atmosphere is dense near the surface of the Earth and protects life on the planet Earth. As altitude increases, air density in the layers of the atmosphere decrease. 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. The stratosphere is the second layer of the atmosphere. 10. It extends above the tropopause to an altitude of 50 km above the earth. The atmosphere gradually changes as the climate and weather change. 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. It is seen in high latitude areas as shimmering curtains of lights that are visible at night. At the outer limit of the magnetic field is the magnetosphere. Ice clouds form in this layer which is visible when lighted from beneath during sunset. As previously mentioned, the stratosphere is one of the five layers that make up the Earth's atmosphere. 3. [6], The mechanism describing the formation of the ozone layer was described by British mathematician Sydney Chapman in 1930. This decrease in temperature with altitude is what causes convection to occur in the troposphere. One of the most surprising things about the stratosphere is not its characteristics but about what you find in this layer. Autumn Skies Online Pty Ltd is compensated for referring traffic and business to these companies., The Earth's atmosphere consists of five layers. In this article, we are going to learn about the atmosphere. 13. 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. One wild characteristic of the stratosphere is a phenomenon that occurs, which is known as blue jets. This layer is 22 miles (35 kilometers) thick. Why Is Carbon Important? 21. Ozone (O3) photolysis produces O and O2. Within no time, the vapor from the exhaust freezes and turns visible. Commercial passenger jets fly in the lower stratosphere, partly because this less-turbulent layer provides a smoother ride. The atmosphere surrounds our planet like the peel of an orange. The stratosphere is very dry air and contains little water vapor. Planes that are low on fuel also fly at this altitude because they can cover more distance than in the troposphere while using less fuel and encountering less turbulence. The resultant breaking causes large-scale mixing of air and other trace gases throughout the midlatitude surf zone. Clouds rarely form in the stratosphere for this reason as well, as the air is very dry. if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[300,250],'ownyourweather_com-large-billboard-2','ezslot_3',116,'0','0'])};__ez_fad_position('div-gpt-ad-ownyourweather_com-large-billboard-2-0');if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[300,250],'ownyourweather_com-large-billboard-2','ezslot_4',116,'0','1'])};__ez_fad_position('div-gpt-ad-ownyourweather_com-large-billboard-2-0_1');if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[300,250],'ownyourweather_com-large-billboard-2','ezslot_5',116,'0','2'])};__ez_fad_position('div-gpt-ad-ownyourweather_com-large-billboard-2-0_2');if(typeof ez_ad_units != 'undefined'){ez_ad_units.push([[300,250],'ownyourweather_com-large-billboard-2','ezslot_6',116,'0','3'])};__ez_fad_position('div-gpt-ad-ownyourweather_com-large-billboard-2-0_3'); .large-billboard-2-multi-116{border:none !important;display:block !important;float:none !important;line-height:0px;margin-bottom:3px !important;margin-left:auto !important;margin-right:auto !important;margin-top:3px !important;max-width:100% !important;min-height:250px;min-width:300px;padding:0;text-align:center !important;}Recent Posts, Copyright 2023 by Own Your Weather. Planting trees is one of the efforts that people have done to try to minimize damage and to help rebuild the damaged ozone layer. Earths atmosphere has six different layers. 16. Air density in this layer gradually decreases as you go higher. Aurora is also referred to as polar light. 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 mesosphere is the third layer of the atmosphere (above the troposphere and stratosphere.) Its depth also varies from 5.5 to 20 miles depending on latitude as well. As a result, it tends to trap any and all gases that enter this region of the atmosphere. Earth's atmosphere is a jacket of gases that surrounds our planet. Meteors burn up in the coldest layer, the mesosphere. Other gases such as carbon dioxide, argon, helium, and neon occupy the remaining portion. It has increased the number of respiratory conditions such as asthma. The stratosphere is situated just above the troposphere, with a thin layer of air called the tropopause separating the two layers. Rocket launches inject exhaust gases into the stratosphere, producing uncertain consequences. We are not permitting internet traffic to Byjus website from countries within European Union at this time. She has taught in K-12 for more than 15 years, and higher education for ten years. 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. Certain swans, cranes, and vultures can fly in the lower stratosphere. The atmosphere is about 500 km thick, with a mix of more than ten different gases. Thats almost as wide as Earth itself. The stratosphere is a layer of extremely stratified air that rises 40 kilometres above the tropopause and comprises about 20% of the atmosphere's mass. 22. Brewer-Dobson Circulation occurs in the stratosphere. [6] Winds in the stratosphere can far exceed those in the troposphere, reaching near 60m/s (220km/h; 130mph) in the Southern polar vortex. Above the stratosphere lies the mesosphere, thermosphere, and exosphere. 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. 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. In fact, the air in the exosphere is constantly - though very gradually - "leaking" out of Earth's atmosphere into outer space. It not only examines what the stratosphere is but also looks at the characteristics or facts that define it. This allows the stratosphere to have an increasing temperature with altitude. The other four layers include the troposphere, mesosphere, thermosphere, and exosphere. 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 . The stratosphere is actually crucial to allowing us to live on earth, because within the stratosphere you will find the ozone layer. The site owner may have set restrictions that prevent you from accessing the site. 77 Amazing, Interesting, and Exciting Facts about the Atmosphere 31. Like an onion, the Earth's atmosphere is composed of many layers. 6. This creates a smoother ride for passengers, as there are few clouds or weather in the stratosphere. Along with the neutral upper atmosphere, the ionosphere forms the boundary between Earth's lower atmosphere where we live and breathe and the vacuum of space. Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. Commercial airliners fly in the lower stratosphere to avoid the weather, travel faster, and save fuel.

The contrails usually become thin at low humidity and high altitudes. Unlike the stratosphere, temperatures once again grow colder as you rise up through the mesosphere. Temperature decreases with height throughout the mesosphere. "Strat" means layer. Write CSS OR LESS and hit save. These gases are chemically inert, although some can react with various chemicals: carbon monoxide, sulfur dioxide, methane, ammonia, ozone, and 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. The stratosphere begins at around 10 kilometers above the surface of the earth. There is no clear-cut upper boundary where the exosphere finally fades away into space. The air density is also very low, making it less turbulent to travel through. 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. The water ice appears younger than we would expect. Ionization takes place in the ionosphere caused by the suns radiation. 17. The stratosphere is located above the troposphere and below the mesosphere. The stratosphere was discovered in 1900 by French meteorologist Lon Teisserenc de Bort. The layer of very rare air above the mesosphere is called the thermosphere. 34. ], 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. It is the only atmospheric layer where temperature inversion occurs and the region where the ozone layer is situated. 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. 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. 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. There are some species of birds capable of flying in the stratosphere. It acts as a giant sponge and absorbs the vast majority of the sun's dangerous Ultraviolet Light. Mercury's magnetic field is different at its poles. The stratosphere is the second layer of the Earth's atmosphere, and lies approximately 10km to 50km above the Earth's surface. [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. However, just above that is an equally important layer called the stratosphere. This diagram shows some of the features of the stratosphere. Fun Stratosphere Facts for Kids. The lack of particles in the air causes less friction to hold an aircraft back, which requires less power to travel faster and further. As a result of the EUs General Data Protection Regulation (GDPR). The ozone layer is situated within this layer. In many ways, the thermosphere is more like outer space than a part of the atmosphere. It is made up of 78% nitrogen and 21% oxygen. A.A. Scaife, J.R. Knight, G.K. Vallis, C.K. This layer of Earth's atmosphere is about 319 miles (513 kilometers) thick. This diagram shows some of the features of the stratosphere. [21] Bar-headed geese (Anser indicus) sometimes migrate over Mount Everest, whose summit is 8,848m (29,029ft). The ozone layer is a layer of gas within the stratosphere that protects the Earth's surface from harmful ultraviolet sun rays. However, temperature increases with altitude in the stratosphere, which is opposite from the troposphere. The exosphere is really, really big. The timescale of this rapid mixing is much smaller than the much slower timescales of upwelling in the tropics and downwelling in the extratropics. They go from the ground all the way to outer space. Meteorological phenomena are limited to the troposphere since they result from the earths rotation and suns radiation on the atmosphere. Louise Fisher has taught middle school students introductory physics topics for two years. Mercury has an atmosphere that changes with its distance to the Sun. It is important because it contains the ozone layer, which protects the Earth from harmful UV rays. It is the only atmospheric layer where temperature inversion occurs and the region where the ozone layer is situated. Skin cancer frequency is increasing due to the thinning of the ozone layer. Ozone is a chemical compound consisting of three oxygen atoms. It reaches up to the mesosphere, with another thin layer of air called the stratopause separating them. Also, magnetic and south poles reverse at uneven intervals of hundreds of thousands of years. [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. As mentioned in the introduction, certain birds such as cranes, swans, and vultures can fly at this altitude. This includes the troposphere, mesosphere, thermosphere, exosphere, and stratosphere. In addition, solar proton events can significantly affect ozone levels via radiolysis with the subsequent formation of OH. The troposphere is the lowest layer of our atmosphere. Scientists have been warning people for many years about the damage we are doing to the ozone layer. The coldest temperatures in Earths atmosphere, about -90 C (-130 F), are found near the top of this layer. The first is due to the reaction of hydroxyl radicals (OH) with ozone. However, this feature allows commercial airliners to fly in the lower stratosphere while traveling faster and save fuel. - This is the second layer of the atmosphere from the surface of the earth, and lies between the troposphere and the mesosphere. This layer separates the rest of the atmosphere from outer space. Air pressure drops, and temperatures get colder, as you climb higher in the troposphere. The exosphere gradually fades away into the realm of interplanetary space. Most clouds appear here, mainly because 99% of the water vapor in the atmosphere is found in the troposphere. 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. 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. Folland. It keeps us warm, it gives us oxygen to breathe, and its where our weather happens. [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. When greenhouse gases rise into the atmosphere, they form chloride ions that destroy the ozone layer by making holes in it. 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. The stratosphere is the second layer of the atmosphere, which is composed of a total of five layers. Luckily the situation has improved since the ban of chlorofluorocarbon. 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. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. The stratosphere can be as deep 20 miles or as shallow as 5.5 miles. The troposphere, the lowest layer, is right below the stratosphere. Clouds form due to convection, which is uncommon in the stratosphere. Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. Many satellites actually orbit Earth within the thermosphere! Blue jets are an extremely rare form of lightning or electrical discharge from clouds in the troposphere. Because of this temperature stratification, there is little convection and mixing in the stratosphere, so the layers of air there are quite stable. That means that to get to outer space, you have to be really far from Earth. It's about 6,200 miles (10,000 kilometers) thick. Hare, J.R. Knight. Mesosphere lies between 50-85 km above sea level. The stratosphere has many defining features that make it a unique part of the atmosphere. Earth is a great planet to live on because it has a wonderful atmosphere around it. In 1985, they observed a hole in the ozone layer above the Antarctic. It contains 80% of the atmospheric weight, making it the densest layer. The stratosphere extends from the top of the troposphere to about 50 km (31 miles) above the ground. The stratosphere ( / strtsfr, - to -/) is the second layer of the atmosphere of the Earth, located above the troposphere and below the mesosphere. This layer is 22 miles (35 kilometers) thick. Privacy Policy This is the opposite of what happens in the troposphere, the layer of the atmosphere closest to Earth. 90% of the ozone layer is found in the stratosphere's upper crust. The main gases are nitrogen and oxygen, which make up 99% of the atmosphere. It is enough to cover the entire earths surface with 1 cm of rain. As it absorbs the UV light, it absorbs energy. Solar ultraviolet radiation (sunlight) separates an oxygen molecule into two different oxygen atoms in the first step. Weather balloons also rise up to this level of the atmosphere to collect data without interference of storm clouds. (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.).
