#1. 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. Acid rains form when nitrogen oxide or Sulphur dioxide combines with water vapor in the atmosphere. Rocket launches inject exhaust gases into the stratosphere, producing uncertain consequences. Commercial passenger jets fly in the lower stratosphere, partly because this less-turbulent layer provides a smoother ride. Because of this temperature stratification, there is little convection and mixing in the stratosphere, so the layers of air there are quite stable. In this region, the temperature increases with height. The atmosphere has nearly 37.5 million billion gallons of water at any given time. That's the opposite of how the . Stratosphere. This is exactly the opposite of the behavior in the troposphere in which we live, where temperatures drop with increasing altitude. The exosphere gradually fades away into the realm of interplanetary space. OH is formed by the reaction of electrically excited oxygen atoms produced by ozone photolysis, with water vapor. This allows the stratosphere to have an increasing temperature with altitude. They are much similar to warm breath during cold weather. 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. In addition, solar proton events can significantly affect ozone levels via radiolysis with the subsequent formation of OH. 30. The stratosphere (/strtsfr, -to-/) is the second layer of the atmosphere of the Earth, located above the troposphere and below the mesosphere. CTRL + SPACE for auto-complete. 33. It reaches up to the mesosphere, with another thin layer of air called the stratopause separating them. Layers of the atmosphere: troposphere, stratosphere, mesosphere and thermosphere. The troposphere, the lowest layer, is right below the stratosphere. 9. Ionization takes place in the ionosphere caused by the suns radiation. The increase of temperature with altitude is a result of the absorption of the Sun's ultraviolet (UV) radiation by the ozone layer. 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. Thats the opposite of how the layers work in the troposphere, where we live. As mentioned in the introduction, certain birds such as cranes, swans, and vultures can fly at this altitude. This is also where you'll find low Earth orbit satellites. All Rights Reserved. Planes and jets will sometimes choose to fly in the stratosphere, where there are no clouds or weather that can affect the ride. . 5. Temperatures in the upper thermosphere can range from about 500 C (932 F) to 2,000 C (3,632 F) or higher. This layer of Earth's atmosphere is about 319 miles (513 kilometers) thick. 8. The wind, which is the air current, is generated when the hot air rises and gets replaced by colder air. 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. It keeps us warm, it gives us oxygen to breathe, and its where our weather happens. Commercial airliners typically cruise at altitudes of 912km (30,00039,000ft) which is in the lower reaches of the stratosphere in temperate latitudes. 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. The photosynthesis process enables plants to take up carbon dioxide and release oxygen into the atmosphere. The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high (5 to 9 miles). The thermosphere extends from about 90 km to 500 kmand 1,000 km above our planet. The atmosphere is one of four spheres of the earth, which include the atmosphere, the hydrosphere, the biosphere, and the lithosphere. Because of this, jet aircraft and weather balloons reach their maximum operational altitudes within the stratosphere. 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. However, it is made up out of five different layers: The troposphere, stratosphere, mesosphere, thermosphere, and exosphere. She has taught in K-12 for more than 15 years, and higher education for ten years. 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. Though the atmosphere may appear uniform to the naked eye, it is actually similar to a layer cake. The stratosphere also contains the ozone layer, which absorbs harmful ultraviolet radiation as it enters our atmosphere from the sun. 29. This increase of temperature with altitude is characteristic of the stratosphere; its resistance to vertical mixing means that it is stratified. In the 1900s, Hungarian physicist Theodore von Krmn determined the boundary to be around 50 miles up, or roughly 80 kilometers above sea level. The 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. This layer of our atmosphere has its own set of layers. It is the second layer of the atmosphere as you go upward. These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure. These elements react with toxic gases, salt, smoke, and volcanic ash. Be grateful! There are a few other atmospheric layers as well -- you can take a look at a diagram of these below. It comprises the magnetosphere and ionosphere. [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. Why Is Carbon Important? But there are no mountains high enough to reach the stratosphere, so you dont have to worry about that. It is important because it contains the ozone layer, which protects the Earth from harmful UV rays. 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. This is due to gravity, but mostly due to the temperature inversion in the tropopause that prevents gases from entering the layer. 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 ozone layer is a layer of gas within the stratosphere that protects the Earth's surface from harmful ultraviolet sun rays. She earned her bachelor's in Physics and Astronomy from the University of North Carolina at Asheville. They are found at altitudes of 15 to 25 km (9.3 to 15.5 miles) and form only when temperatures at those heights dip below -78 C. They appear to help cause the formation of the infamous holes in the ozone layer by "encouraging" certain chemical reactions that destroy ozone. The next layer up is called the stratosphere. 2. Ionosphere plays a vital role in radio signals broadcast on the earths surface. Various types of waves and tides in the atmosphere influence the stratosphere. 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. 23. Dr. Rachel Tustin has a PhD in Education focusing on Educational Technology, a Masters in English, and a BS in Marine Science. Unlike the troposphere, it contains little water vapor so there are no clouds in this layer of the atmosphere. The atmosphere has nearly 37.5 million billion gallons of water at any given time. As altitude increases, air density in the layers of the atmosphere decrease. I would definitely recommend Study.com to my colleagues. Layers of the atmosphere: troposphere, stratosphere, mesosphere . Because the temperature in the tropopause and lower stratosphere is largely constant with increasing altitude, very little convection and its resultant turbulence occurs there. The ozone layer lies in the stratosphere, which absorb the majority of harmful UV radiation from the sun. Bacterial life survives in the stratosphere, making it a part of the biosphere. The contrails usually become thin at low humidity and high altitudes. Because of this, few clouds are found in this layer and almost all clouds occur in the lower, more humid troposphere. [21] Bar-headed geese (Anser indicus) sometimes migrate over Mount Everest, whose summit is 8,848m (29,029ft). 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. Above the stratosphere lies the mesosphere, thermosphere, and exosphere. Close to the tropopause, temperatures start at approximately -51 Celsius (-60 Fahrenheit) and continue to rise until reaching the stratopause, where temperatures reach -15 Celsius (5 Fahrenheit). The following list highlights the characteristics and facts of the stratosphere in more detail. The QBO induces a secondary circulation that is important for the global stratospheric transport of tracers, such as ozone[14] or water vapor. The stratosphere is a layer of Earth's atmosphere. The top of the stratosphere occurs at an altitude of 50 km (31 miles). The composition of the atmosphere of each celestial body is different. Ozone protects life on Earth from the Sun's ultraviolet (UV) radiation. It helps in propagation of the radio waves used in telecommunication. Once you leave the stratosphere, and enter the mesosphere, the temperature dramatically decreases until plummeting to around -184 degrees Fahrenheit. No tracking or performance measurement cookies were served with this page. The stratosphere is one of five layers of the atmosphere. Autumn Skies Online Pty Ltd is compensated for referring traffic and business to these companies., The Earth's atmosphere consists of five layers. 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. Sunlight is reflected in every direction by the gases present in the atmosphere. 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). Convection is the process whereby warm air rises and cooler air descends. The atmosphere is dense near the surface of the Earth and protects life on the planet Earth. 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. Certain swans, cranes, and vultures can fly in the lower stratosphere. This layer is 22 miles (35 kilometers) thick. Without it, the earths surface would be so cold that living here would not be possible. In fact, the air in the exosphere is constantly - though very gradually - "leaking" out of Earth's atmosphere into outer space. The Stratosphere also has three thrill rides at the top. The air in the stratosphere is extremely thin, which makes it impossible to breathe at this level. The stratosphere is situated just above the troposphere, with a thin layer of air called the tropopause separating the two layers. Meteors burn up in the coldest layer, the mesosphere. Clouds rarely form in the stratosphere for this reason as well, as the air is very dry. 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. The stratosphere is very cold, ranging in temperatures from negative 68F to negative 5F. Cred: NASA's Scientific Visualization Studio 3. 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. (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.). The other four layers include the troposphere, mesosphere, thermosphere, and exosphere. The stratosphere was discovered in 1900 by French meteorologist Lon Teisserenc de Bort. The stratosphere is the second layer of the atmosphere, in between the troposphere and the mesosphere. The stratosphere begins at around 10 kilometers above the surface of the earth. Three Highest Thrill Rides in the World. Ozone is a chemical compound consisting of three oxygen atoms. Earth's atmosphere has six layers: the troposphere, the stratosphere, the mesosphere, the thermosphere, the ionosphere, and the exosphere. The top of the stratosphere is called the stratopause, above which the temperature decreases with height. Unlike the stratosphere, temperatures once again grow colder as you rise up through the mesosphere. It changes sometimes unpredictably It borders the mesosphere above through a thin transitional space called the stratopause. 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. (Learn more about Nacreous or Polar Stratospheric Clouds in this article.). She currently works as a physicist assistant at a cancer treatment center. . The aurora, the Northern Lights and Southern Lights, occur in the thermosphere. The rides, which are called The Big Shot, Insanity and X-Scream, are equally terrifying and exciting. Stratosphere is the second layer. 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 next higher layer above the stratosphere is the mesosphere. 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). 11. Mesosphere lies between 50-85 km above sea level. Its upper edge has maximum ozone concentration, referred to as the ozone belt. Each year, this large amount of water is recycled about 40 times. The stratosphere is where youll find the very important ozone layer. It has different layers with different qualities. The ionosphere is not a distinct layer like the others mentioned above. It starts to glow, and the rocks begin to fly off. [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. Facts About The Mesosphere What It Is And Its Defining Characteristics, The 5 Layers Of The Atmosphere Their Composition, Characteristics, And Importance Explained, Fallstreak Holes: What They Are And How They Form, Bubble Clouds: Defining Mammatus Clouds And How They Form, Noctilucent Clouds: Defining Night Shining Clouds And How They Form. 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. Above the stratosphere is the mesosphere. The particles in this layer are electrically charged, and when they hit each other, aurora australis can be observed. 7. 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. 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]. Its concentration in the atmosphere naturally fluctuates depending on seasons and latitudes, but it was . (The fuel consumption depends on the drag, which is related to the lift by the lift-to-drag ratio.) 10. We live in the troposphere, which is the layer of the atmosphere closest to earth. 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 starts just above the troposphere and extends to 50 kilometers (31 miles) high. 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. The ozone layer is situated within this layer. The mesosphere is a layer of Earth's atmosphere. The ionosphere stretches roughly 50 to 400 miles above Earth's surface, right at the edge of space. Autumn Skies Online Pty Ltd also participates in affiliate programs with Clickbank, CJ, ShareASale, and other sites. 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. Due to the lack of vertical convection in the stratosphere, materials that get into the stratosphere can stay there for long times. Temperatures rise as one moves upward through the stratosphere. We take a closer look at the stratosphere and its defining characteristics. This article focus on the stratosphere, Earth's second layer. Planes fly in the stratosphere to avoid turbulence and fly longer distances using less fuel. On November 29, 1973, a Rppell's vulture (Gyps rueppelli) was ingested into a jet engine 11,278m (37,000ft) above the Ivory Coast. Ozone is a blue pungent-smelling gas that helps to absorb the ultraviolet radiation in the sun rays. The stratosphere contains the ozone layer, which shields the Earth from harmful radiation emitted from the Sun. The waves and tides influence the flows of air in the stratosphere and can also cause regional heating of this layer of the atmosphere. Middle School Earth Science: Tutoring Solution, Earth's Spheres & Structure: Tutoring Solution, Earth's Internal Layers: Crust, Mantle & Core, Psychological Research & Experimental Design, All Teacher Certification Test Prep Courses, Stratosphere Facts: Fun Facts About the Stratosphere, How The Earth is Shaped: Earthquakes, Faults & Tsunamis, What is Earth? [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. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. The troposphere, the lowest layer, is right below the stratosphere. 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. PSCs appear in the lower stratosphere near the poles in winter. 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. Learn about the stratosphere, including the stratosphere's definition and importance. The ozone layer, which absorbs and scatters the . The more humid the atmosphere is, the thicker the contrails will be. Ozone (O3) photolysis produces O and O2. They are a combination of supercooled water and nitric acid that develop at very low temperatures.

It is the second layer of the atmosphere as you go upward. It extends upward to a height of about 85 km (53 miles) above our planet. You might have seen planes leaving white condensation trails. Most clouds appear here, mainly because 99% of the water vapor in the atmosphere is found in the troposphere. The timescale of this rapid mixing is much smaller than the much slower timescales of upwelling in the tropics and downwelling in the extratropics. What's in the Atmosphere? As previously mentioned, the stratosphere is one of the five layers that make up the Earth's atmosphere. The stratosphere accounts for approximately 24% of the earth's total atmosphere. There is very little water vapor in this layer of the atmosphere, so clouds are a rare occurrence. 4. It has a very important job: to protect us from harmful energy from the Sun, called radiation. 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. The stratosphere is very dry air and contains little water vapor. 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.
