The layer made of 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 more humid the atmosphere is, the thicker the contrails will be. Above the stratosphere is the mesosphere. Here are 50 Interesting facts about the atmosphere that you probably didnt know. Convection is when gasses cool down as they rise, allowing them to condense onto air particles and form clouds. The atmosphere gradually changes as the climate and weather change. ], 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. Acid rains form when nitrogen oxide or Sulphur dioxide combines with water vapor in the atmosphere. The stratosphere the atmosphere's second layer, and is located right above the troposphere and right below the mesosphere. The troposphere is the lowest layer of our atmosphere. This article focus on the stratosphere, Earth's second layer. The composition of the atmosphere of each celestial body is different. The next higher layer above the stratosphere is the mesosphere. This layer of Earth's atmosphere is about 319 miles (513 kilometers) thick. The mesosphere is directly above the stratosphere and below the thermosphere. The ionosphere is not a distinct layer like the others mentioned above. The rising air is literally freeze dried; the stratosphere is a very dry place. It is the only atmospheric layer where temperature inversion occurs and the region where the ozone layer is situated. It keeps us warm, it gives us oxygen to breathe, and its where our weather happens. The chlorine atoms are recycled when ClO reacts with O in the upper stratosphere, or when ClO reacts with itself in the chemistry of the Antarctic ozone hole. They shoot upwards through the stratosphere in a blue column to altitudes as high as 50km! In this article, we are going to learn about the atmosphere. Just like the troposphere, its depth varies with latitude. Stratopause is the connection between the mesosphere and stratosphere. This increase of temperature with altitude is characteristic of the stratosphere; its resistance to vertical mixing means that it is stratified. Most of the clouds form in the troposphere, just below the stratosphere. 30. 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. They have been observed by airline pilots and the international space station. We are not permitting internet traffic to Byjus website from countries within European Union at this time. Various types of waves and tides in the atmosphere influence the stratosphere. Ninety-nine percent of the gases that compose the atmosphere are located below a height of 32 km (20 miles). It borders the troposphere below through a thin transitional space called the tropopause.

The stratosphere also contains the ozone layer, which absorbs harmful ultraviolet radiation as it enters our atmosphere from the sun. Interestingly, the most significant portion of the atmosphere is located within twelve kilometers of the earths surface. Many satellites actually orbit Earth within the thermosphere! 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. 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]. 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. Because of this temperature stratification, there is little convection and mixing in the stratosphere, so the layers of air there are quite stable. Due to this effect, temperatures in the stratosphere actually increase from about negative {eq}60 {/eq} F up to about negative {eq}5 {/eq} F with altitude. Also, magnetic and south poles reverse at uneven intervals of hundreds of thousands of years. 32. 16. Life as we know it wouldnt be possible without this layer of protection. It is called stratosphere because it is stratified in temperature, with warmer layers higher up and cooler layers farther down. It keeps us warm, gives us oxygen to breathe, and it is where our weather happens. We now know that there are additional ozone loss mechanisms and that these mechanisms are catalytic meaning that a small amount of the catalyst can destroy a great number of ozone molecules. What Causes Air Pollution? He concluded that there was another layer in the atmosphere above the troposphere, which he called the stratosphere. It has different layers with different qualities. 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. Most meteors burn up in the mesosphere. The jet stream flows near the border between the troposphere and the stratosphere. It contains 80% of the atmospheric weight, making it the densest layer. 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. Its like a teacher waved a magic wand and did the work for me. It helps in propagation of the radio waves used in telecommunication. On top of that, air samples from this altitude have shown that certain types of bacteria and microbes are present in the stratosphere, making it the closest to space and furthest from the Earth's surface that humans have found life naturally living. A rare type of electrical discharge, somewhat akin to lightning, occurs in the stratosphere. Discover fun facts about the stratosphere and stratosphere characteristics. stratosphere, layer of Earth's atmosphere lying between the troposphere and the mesosphere. 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 . 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. 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 stratosphere is where youll find the very important ozone layer. 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. Though the atmosphere may appear uniform to the naked eye, it is actually similar to a layer cake. 21. Because of this, few clouds are found in this layer and almost all clouds occur in the lower, more humid troposphere. Theexosphereis really, really big. [22][23], In 1902, Lon Teisserenc de Bort from France and Richard Assmann from Germany, in separate but coordinated publications and following years of observations, published the discovery of an isothermal layer at around 1114km, which is the base of the lower stratosphere. However, temperature increases with altitude in the stratosphere, which is opposite from the troposphere. Above the troposphere and below the mesosphere, we have the stratosphere. OH is formed by the reaction of electrically excited oxygen atoms produced by ozone photolysis, with water vapor.

The ionosphere stretches roughly 50 to 400 miles above Earth's surface, right at the edge of space. The air in the stratosphere is about 1000 thinner than the air at sea level in the troposphere. 17. Blue jets are an extremely rare form of lightning or electrical discharge from clouds in the troposphere. 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. In fact, the air in the exosphere is constantly - though very gradually - "leaking" out of Earth's atmosphere into outer space. The stratosphere contains the ozone layer, which shields the Earth from harmful radiation emitted from the Sun. From space, the earth is seen as a blue halo. The stratosphere is very cold, ranging in temperatures from negative 68F to negative 5F. Certain birds can fly to this altitude, including cranes, swans, and vultures. As a result, it tends to trap any and all gases that enter this region of the atmosphere. - 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? It occurs naturally in small (trace) amounts in the upper atmosphere (the stratosphere). What are the characteristics of the five layers of the atmosphere? The atmospheric balance is jeopardized by human activities that cause global warming, greenhouse effect, ozone belt destruction, air contamination, and acid rains. 2023 TheFactFile.Org. Its magnetic field goes up to 60,000 km into space. As this article clearly illustrated, the stratosphere has a crucial role to play in maintaining the atmosphere and all life in it. Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. 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. Meteors burn up in the coldest layer, the mesosphere. 23. Composed of mostly nitrogen and oxygen, the stratosphere also contains the ozone layer. 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. 24. The atmosphere surrounds our planet like the peel of an orange. As a result, air circulation is not as prevalent in this layer of the atmosphere, making it difficult for some gasses to escape. Mesosphere lies between 50-85 km above sea level. So, what does the stratosphere do? Thats the opposite of how the layers work in the troposphere, where we live. They go from the ground all the way to outer space. There are little to no clouds in the stratosphere from the lack of convection. 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. The layer made of layers Above the troposphere and below the mesosphere, we have the stratosphere. The bottom of the stratosphere is around 10 km (6.2 miles or about 33,000 feet) above the ground at middle latitudes. [4] The temperature inversion is in contrast to the troposphere, near the Earth's surface, where temperature decreases with altitude. Mercury has an atmosphere that changes with its distance to the Sun. It extends from about 50 to 85 km (31 to 53 miles) above our planet. Rocket launches inject exhaust gases into the stratosphere, producing uncertain consequences. This is the opposite of what happens in the troposphere, the layer of the atmosphere closest to Earth. 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. High-energy X-rays and UV radiation from the Sun are absorbed in the thermosphere, raising its temperature to hundreds or at times thousands of degrees. It is possible to send research balloons into the stratosphere. Enrolling in a course lets you earn progress by passing quizzes and exams. Rainbow Facts: What Is A Rainbow And How Does It Occur? The atmosphere is dense near the surface of the Earth and protects life on the planet Earth. The destruction of the ozone layer lets an enormous amount of ultraviolet rays reach the earth, which leads to skin cancer and cataracts in humans and animals alike. 4 One of the most surprising things about the stratosphere is not its characteristics but about what you find in this layer. 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. These events often precede unusual winter weather [16] and may even be responsible for the cold European winters of the 1960s.[17]. The air in the stratosphere is extremely thin, which makes it impossible to breathe at this level. The Earth's atmosphere is very important, as each layer plays a role for life on Earth. The stratosphere also traps certain gasses known as CFC's, which are chemicals derived from aerosol. Radicals produced from the homolytically split oxygen molecules combine with molecular oxygen to form ozone. The importance of the stratosphere is highlighted by the presence of the ozone layer, without which no life on Earth will be possible. The Earth's atmosphere is made up of roughly 78% nitrogen, 21% oxygen, 0.9% argon, and 0.1% other gases. It starts to glow, and the rocks begin to fly off. 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. Dr. Rachel Tustin has a PhD in Education focusing on Educational Technology, a Masters in English, and a BS in Marine Science. The stratosphere is the second layer of the Earth's atmosphere, and lies approximately 10km to 50km above the Earth's surface. These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure. 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. Earth's atmosphere is a jacket of gases that surrounds our planet. 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). It extends upward to a height of about 85 km (53 miles) above our planet. The resultant breaking causes large-scale mixing of air and other trace gases throughout the midlatitude surf zone. Certain birds will even fly in the stratosphere, including swans, cranes, and vultures! Be grateful! Its concentration in the atmosphere naturally fluctuates depending on seasons and latitudes, but it was . [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. 20. Stratosphere is the second layer. Moreover, meteorites falling over the earth burn in this layer. Why Is Carbon Important? This decrease in temperature with altitude is what causes convection to occur in the troposphere. Most airplanes or jets travel in the lower part of the stratosphere. Most clouds appear here, mainly because 99% of the water vapor in the atmosphere is found in the troposphere. Troposphere. As altitude increases, air density in the layers of the atmosphere decrease. Above the troposphere and below the mesosphere, we have the stratosphere. But there are no mountains high enough to reach the stratosphere, so you dont have to worry about that. This border is known as the Karman line. We humans live in the troposphere, and nearly all weather occurs in this lowest layer. 27. On October 24, 2014, Alan Eustace became the record holder for reaching the altitude record for a manned balloon at 135,890ft (41,419m). 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 exosphere gradually fades away into the realm of interplanetary space. 5. Ozone (O3) is a highly reactive gas whose molecules are comprised of three oxygen atoms. The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high (5 to 9 miles). Earths atmosphere is similar to a jacket for our planet. The stratosphere is a layer of Earth's atmosphere. Since almost almost weather activity is limited to the troposphere and almost no water vapor is present in the stratosphere, Polar Stratospheric Clouds is the only visual meteorological phenomenon that can be observed in the stratosphere. It is the second layer of the atmosphere as you go upward. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. Since the stratosphere has increasing temperature with elevation, convection is very rare. That's much thicker than the inner layers of the atmosphere, but not nearly as thick as the exosphere. At an altitude of 100 km above sea level, a border represents the separation between the atmosphere and outer space. 25. This breaking is much more pronounced in the winter hemisphere where this region is called the surf zone. The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high. That trend of rising temperatures with altitude means that air in the stratosphere lacks the turbulence and updrafts of the troposphere beneath. [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. Once you leave the stratosphere, and enter the mesosphere, the temperature dramatically decreases until plummeting to around -184 degrees Fahrenheit. The HO2 radical produced by the reaction of OH with O3 is recycled to OH by reaction with oxygen atoms or ozone. Clouds form due to convection, which is uncommon in the stratosphere. Heat is produced in the process of the formation of Ozone, and this heat is responsible for . There are a few other atmospheric layers as well -- you can take a look at a diagram of these below. Mercury has water ice and organics. Strat means layer. The lack of particles in the air causes less friction to hold an aircraft back, which requires less power to travel faster and further. While the stratosphere is dry, additional water vapor is produced in situ by the photochemical oxidation of methane (CH4). We live in the troposphere, which is the layer of the atmosphere closest to earth. The first is due to the reaction of hydroxyl radicals (OH) with ozone. 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. The Earth's atmosphere is a mixture of several gases. The lower boundary of the stratosphere is called the tropopause; the upper boundary is called the stratopause. As a result of the EUs General Data Protection Regulation (GDPR). It has a very important job: to protect us from harmful energy from the Sun, called radiation. 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. 29. 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. 15. Current map of global winds and temperatures at the 10 hPa level. The stratosphere can be as deep 20 miles or as shallow as 5.5 miles. #1. "Strat" means layer. As mentioned in the introduction, certain birds such as cranes, swans, and vultures can fly at this altitude. Weather balloons also rise up to this level of the atmosphere to collect data without interference of storm clouds. The atmosphere comprises five layers: troposphere, stratosphere, mesosphere, thermosphere and exosphere. Temperatures in the upper thermosphere can range from about 500 C (932 F) to 2,000 C (3,632 F) or higher. Its depth also varies from 5.5 to 20 miles depending on latitude as well. 7. The temperatures in the ozone belt are higher than in the troposphere since the ozone absorbs the ultraviolet rays. A good percentage of the earths population breathes contaminated air, primarily sulfur dioxide and carbon monoxide emitted by industrial factories. The ozone layer lies in the stratosphere, which absorb the majority of harmful UV radiation from the sun. (Learn more about Nacreous or Polar Stratospheric Clouds in this article.). I would definitely recommend Study.com to my colleagues. 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. The stratosphere is the second layer of the atmosphere, which is composed of a total of five layers. Biosphere forms part of the troposphere where life exists. Ozone is important for ensuring that just the right amount of ultraviolet radiation reaches the earth. Since the ozone layer absorbs UV rays from the sun, it heats up, which allows temperatures to increase as altitude increases. The top of the stratosphere occurs at an altitude of 50 km (31 miles). The stratosphere (/strtsfr, -to-/) is the second layer of the atmosphere of the Earth, located above the troposphere and below the mesosphere. [20], Some bird species have been reported to fly at the upper levels of the troposphere. (The fuel consumption depends on the drag, which is related to the lift by the lift-to-drag ratio.) Such is the case for ozone-destroying chemicals called CFCs (chlorofluorocarbons). The height of the bottom of the stratosphere varies with latitude and with the seasons. The stratosphere is the second layer of the atmosphere. 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. 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. Fun Stratosphere Facts for Kids. 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. The exosphere is really, really big. (The ozone layer is too large a topic for this article, but you can read more about it in the following post.). Due to the characteristics of the stratosphere, it is a very important part of Earth's atmosphere. 1. The exosphere gradually fades away into the realm of interplanetary space. Composition of the Earth's 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. What's in the Atmosphere? The rapid photolysis and reformation of ozone heat the stratosphere, resulting in a temperature inversion. The next higher layer above the stratosphere is the mesosphere. 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. The stratosphere is a layer of Earth's atmosphere. These are generated when cold atmospheric air blends with the hot, humid exhaust. Almost all weather is in this region. 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. Earths atmosphere has six different layers. She currently works as a physicist assistant at a cancer treatment center. Stratosphere is the second layer. 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. It extends above the tropopause to an altitude of 50 km above 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 infamous ozone layer is found within the stratosphere. A single chlorine atom can destroy more than a hundred thousand ozone molecules. The ozone layer is a layer of gas within the stratosphere that protects the Earth's surface from harmful ultraviolet sun rays. The next layer up is called the stratosphere. 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. This is due to gravity, but mostly due to the temperature inversion in the tropopause that prevents gases from entering the layer. Folland. The atmosphere consists of five distinct layers, with the stratosphere being the second, situated just above the troposphere.
