It is like a giant magnet and retains high-energy particles, thereby protecting the earth. It surrounds the globe and protects it by absorbing the infrared rays from the sun. It lies above the troposphere, the layer closest to Earth, and below the mesosphere. In this article, we are going to learn about the atmosphere. 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. Atmosphere facts: ninety-nine percent of the gases that compose the atmosphere are located below a height of 32 km (20 miles). Because of this, few clouds are found in this layer and almost all clouds occur in the lower, more humid troposphere. The atmosphere comprises five layers: troposphere, stratosphere, mesosphere, thermosphere and exosphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet. 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. https://en.wikipedia.org/w/index.php?title=Stratosphere&oldid=1140010063, This page was last edited on 18 February 2023, at 00:23. Nasa Ozone Watch: Ozone facts The stratosphere is the second layer of the Earth's atmosphere, and lies approximately 10km to 50km above the Earth's surface. The stratosphere the atmosphere's second layer, and is located right above the troposphere and right below the mesosphere. Bacterial life survives in the stratosphere, making it a part of the biosphere. Ozone depletion is a major environmental problem because it increases the amount of ultraviolet (UV . Moreover, it regulates the temperature extremes that are likely to occur between day and night. 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. 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 stratosphere ( / strtsfr, - to -/) is the second layer of the atmosphere of the Earth, located above the troposphere and below the mesosphere. Polar Stratospheric Clouds develop in this layer near the poles at an altitude of 15 - 25 kilometers. The composition of the atmosphere of each celestial body is different. 7. The air in the stratosphere is about 1000 thinner than the air at sea level in the troposphere. 29. Rainbow Facts: What Is A Rainbow And How Does It Occur? "Strat" means layer. The photosynthesis process enables plants to take up carbon dioxide and release oxygen into the atmosphere. Earths atmosphere is similar to a jacket for our planet. The amount of water vapour in the stratosphere is very low, and because of this there are no clouds in the stratosphere. They are much similar to warm breath during cold weather. The height of the bottom of the stratosphere varies with latitude and with the seasons. 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. Its upper edge has maximum ozone concentration, referred to as the ozone belt. [6], The mechanism describing the formation of the ozone layer was described by British mathematician Sydney Chapman in 1930. Variations in the amount of energy coming from the Sun exert a powerful influence on both the height of the top of this layer and the temperature within it. These events often precede unusual winter weather [16] and may even be responsible for the cold European winters of the 1960s.[17]. The stratospheric air is extremely thin and dry since the vast majority of atmospheric gases (and weather activity) are limited to the troposphere. The ozone layer is a layer of gas within the stratosphere that protects the Earth's surface from harmful ultraviolet sun rays. 40 Unbelievable But True Troposphere Facts | Kidadl Since the stratosphere has increasing temperature with elevation, convection is very rare. The stratosphere also has an increasing temperature with increasing altitude, which is different than what happens in the troposphere. Ozone layer | Description, Importance, & Facts | Britannica 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. (Learn more about Nacreous or Polar Stratospheric Clouds in this article.). Discover fun facts about the stratosphere and stratosphere characteristics. Earth's atmosphere has a series of layers, each with its own specific traits. While the stratosphere is dry, additional water vapor is produced in situ by the photochemical oxidation of methane (CH4). The Concorde aircraft cruised at Mach 2 at about 60,000ft (18km), and the SR-71 cruised at Mach 3 at 85,000ft (26km), all within the stratosphere. She earned her bachelor's in Physics and Astronomy from the University of North Carolina at Asheville. The stratosphere is located above the troposphere and below the mesosphere. Facts About Stratosphere - GKToday All air entering the stratosphere must pass through the tropopause, the temperature minimum that divides the troposphere and stratosphere. The holes in the ozone layer have been recorded above the Antarctica seasonally, as well as in other parts of the world. Each year, this large amount of water is recycled about 40 times. 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. They have been observed by airline pilots and the international space station. Troposphere - The lowest level of our atmosphere is called the Troposphere. What are the characteristics of the five layers of the atmosphere? The stratosphere is one of five layers of the earth's atmosphere. The stratosphere is located above the troposphere and below the mesosphere. #1. As it absorbs the UV light, it absorbs energy. The main gases are nitrogen and oxygen, which make up 99% of the atmosphere. The stratosphere is home to the ozone layer, which is a thin layer of concentrated ozone which plays an essential role in protecting the Earth from dangerous solar radiation. It helps in propagation of the radio waves used in telecommunication. 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. To learn more about each layer of the atmosphere, click the images below. 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. The increase of temperature with altitude is a result of the absorption of the Sun's ultraviolet (UV) radiation by the ozone layer. Unlike the troposphere, the stratosphere actually gets warmer the higher you go! This includes the troposphere, mesosphere, thermosphere, exosphere, and stratosphere. The mesosphere is a layer of Earth's atmosphere. Thats almost as wide as Earth itself. Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. There are a few other atmospheric layers as well -- you can take a look at a diagram of these below. The timescale of this rapid mixing is much smaller than the much slower timescales of upwelling in the tropics and downwelling in the extratropics. These gases are chemically inert, although some can react with various chemicals: carbon monoxide, sulfur dioxide, methane, ammonia, ozone, and water vapor. Of all the atmospheric layers, this is the most closest to the Earth. The stratosphere is the second layer of the atmosphere, in between the troposphere and the mesosphere. The atmosphere is dense near the surface of the Earth and protects life on the planet Earth. It is the only atmospheric layer where temperature inversion occurs and the region where the ozone layer is situated. 5. 9. This list does not contain all the data available about the stratosphere but highlights the key facts and characteristics of this layer. Temperatures rise as one moves upward through the stratosphere. 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. [20], Some bird species have been reported to fly at the upper levels of the troposphere. 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. Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. [21] Bar-headed geese (Anser indicus) sometimes migrate over Mount Everest, whose summit is 8,848m (29,029ft). But its not the same everywhere. 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. Above the stratosphere lies the mesosphere, thermosphere, and exosphere. Radicals produced from the homolytically split oxygen molecules combine with molecular oxygen to form ozone. Thus it means layer which surrounds the earth. The atmosphere has nearly 37.5 million billion gallons of water at any given time. stratosphere The atmospheric layer above the troposphere, which extends on average from about 10 to 50 km above the Earth's surface. Moving upward from ground level, these layers are called the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The other four layers include the troposphere, mesosphere, thermosphere, and exosphere. Most clouds appear here, mainly because 99% of the water vapor in the atmosphere is found in the troposphere. The stratosphere is a layer of Earths atmosphere. The stratosphere extends from from 4 -12 miles (6-20 km) above the Earth's surface to around 31 miles (50 km). 16. The troposphere is where we breath in and is also referred to as the lower atmosphere. Convection is when gases cool as they rise, allowing them to condense on air molecules which form clouds. 5. That trend of rising temperatures with altitude means that air in the stratosphere lacks the turbulence and updrafts of the troposphere beneath. This is due to gravity, but mostly due to the temperature inversion in the tropopause that prevents gases from entering the layer. The jet stream flows near the border between the troposphere and the stratosphere. The rapid photolysis and reformation of ozone heat the stratosphere, resulting in a temperature inversion. The rising air is literally freeze dried; the stratosphere is a very dry place. The rides, which are called The Big Shot, Insanity and X-Scream, are equally terrifying and exciting. Atmosphere Layers: Facts About the Atmosphere Layers In the stratosphere - 'strato' means layer and sphere is the shape of the earth. 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. 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 layer made of layers Above the troposphere and below the mesosphere, we have the stratosphere. This is the opposite of what happens in the troposphere, where an increasing altitude yields a decrease in temperature. The lower boundary of the stratosphere is called the tropopause; the upper boundary is called the stratopause. Earth's Atmospheric Layers | NASA Ozone depletion | Facts, Effects, & Solutions | Britannica Be grateful! The top of the stratosphere occurs at an altitude of 50 km (31 miles). What's in the Atmosphere? The waves and tides influence the flows of air in the stratosphere and can also cause regional heating of this layer of the atmosphere. The more humid the atmosphere is, the thicker the contrails will be. When the ozone absorbs ultraviolet radiation, it actually causes another phenomenon that is used to identify different layers in the atmosphere. The thinning is most pronounced in the polar regions, especially over Antarctica. Planting trees is one of the efforts that people have done to try to minimize damage and to help rebuild the damaged ozone layer. Moreover, meteorites falling over the earth burn in this layer. The atmosphere is one of four spheres of the earth, which include the atmosphere, the hydrosphere, the biosphere, and the lithosphere. Instead, clouds condense in the troposphere. A.A. Scaife, J.R. Knight, G.K. Vallis, C.K. The stratosphere is one of five layers of the earth's atmosphere. Moreover, the distance between the molecules increases as you move up the different layers. 22. It changes sometimes unpredictably It borders the mesosphere above through a thin transitional space called the stratopause. Certain bird species like the common crane, whooper swan, and the Rppel's griffon vulture are capable of flying in the lower stratosphere. Ozone is a gas made up of three oxygen atoms (O 3). 34. 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. Most of the clouds form in the troposphere, just below the stratosphere. 35. Thislayerseparates the rest of the atmosphere from outer space. 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. Earth's atmosphere has six layers: the troposphere, the stratosphere, the mesosphere, the thermosphere, the ionosphere, and the exosphere. 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. The particles in the exosphere do not behave like gases. Ozone (O3) photolysis produces O and O2. But there are no mountains high enough to reach the stratosphere, so you dont have to worry about that. The atmospheric gases must retain the heat in the sun rays and reflect them to the earth to keep it warm. 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 Without it, the earths surface would be so cold that living here would not be possible. Earths atmosphere has six layers: the troposphere, the stratosphere, the mesosphere, the thermosphere, the ionosphere, and the exosphere. The Earth's atmosphere is a mixture of several gases. 77 Amazing, Interesting, and Exciting Facts about the Atmosphere Convection is the process whereby warm air rises and cooler air descends. Gases and dust from volcanic eruptions often meet the same fate, remaining trapped in the stratosphere for months or even longer. Ozone (O3) is a highly reactive gas whose molecules are comprised of three oxygen atoms. 4 This layer is 22 miles (35 kilometers) thick. The atmosphere has nearly 37.5 million billion gallons of water at any given time. The stratosphere is the second layer of the Earth's atmosphere, laying just above the troposphere and below the mesosphere. There is no clear-cut upper boundary where the exosphere finally fades away into space. The word 'stratosphere' is derived from the word 'strato' meaning layer, and 'sphere' which is earth's shape. 11. Fun Stratosphere Facts for Kids. In the lower atmosphere (the troposphere) near the Earth's surface, ozone is created by chemical reactions between air pollutants . The following list highlights the characteristics and facts of the stratosphere in more detail. Aurora is also referred to as polar light. Acid rains form when nitrogen oxide or Sulphur dioxide combines with water vapor in the atmosphere. It starts to glow, and the rocks begin to fly off. The Stratosphere also has three thrill rides at the top. 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. They shoot upwards through the stratosphere in a blue column to altitudes as high as 50km! It is the only atmospheric layer where temperature inversion occurs and the region where the ozone layer is situated. . Earth's atmosphere is a jacket of gases that surrounds our planet. Earth is a great planet to live on because it has a wonderful atmosphere around it. Stratosphere Facts, Characteristics & Composition | What is the 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. The stratosphere also traps certain gasses known as CFC's, which are chemicals derived from aerosol. These free-moving elements continuously escape into space due to ballistic trajectories. As a result of the EUs General Data Protection Regulation (GDPR). 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. It also allows the airplane to stay above the turbulent weather of the troposphere. At the top of the stratosphere, the density of the air is close to zero. They go from the ground all the way to outer space. Exosphere | NASA Space Place - NASA Science for Kids The aurora, the Northern Lights and Southern Lights, occur in the thermosphere. 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). Meteors burn up in the coldest layer, the mesosphere. 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. 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! Stratosphere | NASA Space Place - NASA Science for Kids It is easy & understandable to view our atmosphere as a continuous layer of air. Little-Known Scientific Facts About the Stratosphere Meteorological phenomena are limited to the troposphere since they result from the earths rotation and suns radiation on the atmosphere. 3090 Center Green Drive, Boulder, CO 80301, Virtual Ballooning to Explore the Atmosphere, ACOM | Atmospheric Chemistry Observations & Modeling, CISL | Computational & Information Systems, EdEC | Education, Engagement & Early-Career Development, Government Relations & External Engagement. The atmosphere consists of five distinct layers, with the stratosphere being the second, situated just above the troposphere. [4] Temperatures range from an average of 51C (60F; 220K) near the tropopause to an average of 15C (5.0F; 260K) near the mesosphere. This UV radiation is important for the production of vitamin D in humans, but too much can destroy tissue. The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high. Clouds form when water vapor condenses into a liquid, and with very little water, vapor condensation is virtually impossible. 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. 2. The stratosphere is a layer of Earth's atmosphere. Air is roughly a thousand times thinner at the top of the stratosphere than it is at sea level. That means that to get to outer space, you have to be really far from Earth. The stratosphere protects Earth life from extremely harmful UV rays from the sun. 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. Endeavoring to achieve professional growth through ongoing development of skills and using new and accepted methods of . The wind, which is the air current, is generated when the hot air rises and gets replaced by colder air. This article focus on the stratosphere, Earth's second layer. Stratosphere Definition & Meaning - Merriam-Webster Around the poles, it actually begins at around 7 kilometers, whereas around the equator it can be as high as 20 kilometers. This decrease in temperature with altitude is what causes convection to occur in the troposphere. Stratospheric warming of the polar vortex results in its weakening. As a result, the air in the stratosphere is about 1000 times thinner in the stratosphere than at sea level in the troposphere. The stratosphere is a major stable layer whose base is marked by the tropopause, and where temperatures overall average approximately 60 C.Temperature in the lower stratosphere is isothermal but increases markedly in the upper part, to reach a maximum of . It comprises the magnetosphere and ionosphere. This breaking is much more pronounced in the winter hemisphere where this region is called the surf zone. (The ozone layer is too large a topic for this article, but you can read more about it in the following post.). We live in the troposphere, which is the layer of the atmosphere closest to earth. 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). 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. "Strat" means layer. 77 Exciting Facts about the Atmosphere - LovePsychologys The next layer up is called the stratosphere. The stratosphere is the second layer of the atmosphere, which is composed of a total of five layers. 13. Stratosphere | atmospheric region | Britannica The top of the stratosphere is called the stratopause, above which the temperature decreases with height. 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 stratosphere extends from the tropopause at about 10 to 17 km (about 6 to 11 miles) altitude to its upper boundary (the stratopause) at . Troposphere is the thinnest and closest layer to the earths surface. 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. [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]. 24. From space, the earth is seen as a blue halo. As a result, it tends to trap any and all gases that enter this region of the atmosphere. The ionosphere stretches roughly 50 to 400 miles above Earth's surface, right at the edge of space. N.Butchart, A.A. Scaife, J. Austin, S.H.E. Ozone layer facts and information - Environment However, this feature allows commercial airliners to fly in the lower stratosphere while traveling faster and save fuel. 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. Its like a teacher waved a magic wand and did the work for me. Since blue light has short wavelengths, it gets reflected more compared to other colors. Earths atmosphere has six different layers.
