Within no time, the vapor from the exhaust freezes and turns visible. It has a very important job: to protect us from harmful energy from the Sun, called radiation. Troposphere is the thinnest and closest layer to the earths surface. Be grateful! Certain swans, cranes, and vultures can fly in the lower stratosphere. The coldest temperatures in Earth's atmosphere, about -90 C (-130 F), are found near the top of this layer. Within the stratosphere temperatures increase with altitude (see temperature inversion); the top of the stratosphere has a temperature of about 270 K (3C or 26.6F).[8]. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. The Brief Overview. Endeavoring to achieve professional growth through ongoing development of skills and using new and accepted methods of . The ozone layer, which absorbs and scatters the . But there are no mountains high enough to reach the stratosphere, so you dont have to worry about that. Because of this, few clouds are found in this layer and almost all clouds occur in the lower, more humid troposphere. Planting trees is one of the efforts that people have done to try to minimize damage and to help rebuild the damaged ozone layer. The next higher layer above the stratosphere is the mesosphere. Unlike the stratosphere, temperatures once again grow colder as you rise up through the mesosphere. At the top of the stratosphere, the density of the air is close to zero. The water exists in the form of vapor and invisible to plain eyes. Mercury has an atmosphere that changes with its distance to the Sun. . As the altitude increases, the atmosphere diminishes which is the reason why the air pressure in the exosphere is shallow. The air in the stratosphere is extremely thin, which makes it impossible to breathe at this level. Stratosphere | NASA Space Place - NASA Science for Kids As it absorbs the UV light, it absorbs energy. 50 Interesting Facts About The Atmosphere - Page 2 of 3 - The Fact File The troposphere, the lowest layer, is right below the stratosphere. The stratosphere is the second layer of the atmosphere. Acid rains form when nitrogen oxide or Sulphur dioxide combines with water vapor in the atmosphere. As the ozone layer absorbs UV radiation, it causes the temperature in this layer to increase. PSCs are also called nacreous clouds. 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. The atmosphere is dense near the surface of the Earth and protects life on the planet Earth. Ice clouds form in this layer which is visible when lighted from beneath during sunset. This decrease in temperature with altitude is what causes convection to occur in the troposphere. The jet stream flows near the border between the troposphere and the stratosphere. Strat means layer. 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 bottom of the stratosphere is around 10 km (6.2 miles or about 33,000 feet) above the ground at middle latitudes. Ozone layer | Description, Importance, & Facts | Britannica Above the troposphere and below the mesosphere, we have the stratosphere. It is seen in high latitude areas as shimmering curtains of lights that are visible at night. The particles in this layer are electrically charged, and when they hit each other, aurora australis can be observed. [21] Bar-headed geese (Anser indicus) sometimes migrate over Mount Everest, whose summit is 8,848m (29,029ft). Atmosphere facts: ninety-nine percent of the gases that compose the atmosphere are located below a height of 32 km (20 miles). The HO2 radical produced by the reaction of OH with O3 is recycled to OH by reaction with oxygen atoms or ozone. The stratosphere also contains the ozone layer, which absorbs harmful ultraviolet radiation as it enters our atmosphere from the sun. Privacy Policy Ozone in turn is photolysed much more rapidly than molecular oxygen as it has a stronger absorption that occurs at longer wavelengths, where the solar emission is more intense. The thinning is most pronounced in the polar regions, especially over Antarctica. The rapid photolysis and reformation of ozone heat the stratosphere, resulting in a temperature inversion. There are some species of birds capable of flying in the stratosphere. Polar stratospheric clouds (PSCs) are the exception. It is easy & understandable to view our atmosphere as a continuous layer of air. Its concentration in the atmosphere naturally fluctuates depending on seasons and latitudes, but it was . To unlock this lesson you must be a Study.com Member. This jacket of gases does a lot for us. Thermosphere | NASA Space Place - NASA Science for Kids 34. The stratosphere is located above the troposphere and below the mesosphere. It is the only atmospheric layer where temperature inversion takes place. The other four layers include the troposphere, mesosphere, thermosphere, and exosphere. 21. 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. It surrounds our planet, keeps us warm, gives us oxygen to breathe, and it is where our weather happens. 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 ozone layer is within the stratosphere, which protect the Earth from harmful radiation emitted by the sun. This vertical stratification, with warmer layers above and cooler layers below, makes the stratosphere dynamically stable: there is no regular convection and associated turbulence in this part of the atmosphere. 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. Sunlight is reflected in every direction by the gases present in the atmosphere. This is exactly the opposite of the behavior in the troposphere in which we live, where temperatures drop with increasing altitude. The Stratosphere | Center for Science Education Its upper edge has maximum ozone concentration, referred to as the ozone belt. The exosphere is the very edge of our atmosphere. In comparison, the warmest in the thermosphere. 4 The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high. Cred: NASA's Scientific Visualization Studio 3. Enrolling in a course lets you earn progress by passing quizzes and exams. Facts About the Stratosphere Tower | USA Today [7] Molecular oxygen absorbs high energy sunlight in the UV-C region, at wavelengths shorter than about 240nm. Earth's Atmospheric Layers | NASA There is no clear-cut upper boundary where the exosphere finally fades away into space. Facts About The Mesosphere - What It Is And Its Defining Characteristics 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 similar to a jacket for our planet. 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 atmosphere comprises five layers: troposphere, stratosphere, mesosphere, thermosphere and exosphere. However, this feature allows commercial airliners to fly in the lower stratosphere while traveling faster and save fuel. Interesting Facts About Mercury. 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. 2023 TheFactFile.Org. Louise Fisher has taught middle school students introductory physics topics for two years. It contains most of our Earth's water vapour, and is 78% nitrogen and 21% oxygen. 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 the second layer of the Earth's atmosphere, laying just above the troposphere and below the mesosphere. Just above that is the stratosphere, the area of the atmosphere where passenger airplanes and weather balloons fly. Most meteors burn up in the mesosphere. The stratosphere is a layer of Earth's atmosphere. 90% of the ozone layer is found in the stratosphere's upper crust. Little-Known Scientific Facts About the Stratosphere Life as we know it wouldnt be possible without this layer of protection. Convection is when gases cool as they rise, allowing them to condense on air molecules which form clouds. It also allows the airplane to stay above the turbulent weather of the troposphere. Meteorological phenomena are limited to the troposphere since they result from the earths rotation and suns radiation on the atmosphere. In the lower atmosphere (the troposphere) near the Earth's surface, ozone is created by chemical reactions between air pollutants . When the ozone absorbs ultraviolet radiation, it actually causes another phenomenon that is used to identify different layers in the atmosphere. Facts About Stratosphere Published: April 3, 2016 The stratosphere is the second major layer of Earth's atmosphere, just above the troposphere, and below the mesosphere. - This is the second layer of the atmosphere from the surface of the earth, and lies between the troposphere and the mesosphere. Its magnetic field goes up to 60,000 km into space. Ozone depletion is a major environmental problem because it increases the amount of ultraviolet (UV . Stated another way, it allows the airliner to fly faster while maintaining lift equal to the weight of the plane. No tracking or performance measurement cookies were served with this page. However, just above that is an equally important layer called the stratosphere. Convection is when gasses cool down as they rise, allowing them to condense onto air particles and form clouds. It sets it apart from the other atmospheric layers by temperature rising instead of dropping as altitude increases, a process called temperature inversion. The stratosphere can be as deep 20 miles or as shallow as 5.5 miles. 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. One wild characteristic of the stratosphere is a phenomenon that occurs, which is known as blue jets. Aurora is also referred to as polar light. The stratosphere is one of five layers of the earth's atmosphere. copyright 2003-2023 Study.com. 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. It comprises the magnetosphere and ionosphere. "Strat" means layer. These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure. 3 It borders the stratosphere below through a thin transitional space called the stratopause. The atmospheric balance is jeopardized by human activities that cause global warming, greenhouse effect, ozone belt destruction, air contamination, and acid rains. While common in the troposphere, very little convection takes place in the stratosphere. Moreover, the distance between the molecules increases as you move up the different layers. As a result, air circulation is not as prevalent in this layer of the atmosphere, making it difficult for some gasses to escape. These distances vary slightly due to elevation changes on the Earth. 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. Finally, chlorofluorocarbon molecules are photolysed in the stratosphere releasing chlorine atoms that react with ozone giving ClO and O2. Mercury has water ice and organics. It is the only layer of the atmosphere where temperature inversion occurs. 6. It is called stratosphere because it is stratified in temperature, with warmer layers higher up and cooler layers farther down. It contains the ozone layer and is between the troposphere, the first layer of the atmosphere, and the mesosphere, the third layer of the atmosphere. The next layer up is called the stratosphere. This was based on temperature profiles from mostly unmanned and a few manned instrumented balloons. Temperature decreases with height throughout the mesosphere. Ozone (O3) is a highly reactive gas whose molecules are comprised of three oxygen atoms. The ozone layer is a layer of gas within the stratosphere that protects the Earth's surface from harmful ultraviolet sun rays. It is in the thermosphere that the space shuttle flew. This layer separates the rest of the atmosphere from outer space. This includes its location, what it is composed of, the temperature range, and its density. The image above illustrates the layers of Earth's atmosphere and their approximate distances from the Earth's surface. The stratosphere is located above the troposphere and below the mesosphere. Dr. Rachel Tustin has a PhD in Education focusing on Educational Technology, a Masters in English, and a BS in Marine Science. An increase of altitude in the troposphere makes temperatures decrease, which is why it is much colder on the top of a mountain than on sea level. This diagram shows some of the features of the stratosphere. Layers of the atmosphere: troposphere, stratosphere, mesosphere and thermosphere. The atmosphere consists of five distinct layers, with the stratosphere being the second, situated just above the troposphere. Its depth also varies from 5.5 to 20 miles depending on latitude as well. As a result of the EUs General Data Protection Regulation (GDPR). All air entering the stratosphere must pass through the tropopause, the temperature minimum that divides the troposphere and stratosphere. While the stratosphere is dry, additional water vapor is produced in situ by the photochemical oxidation of methane (CH4). Atmosphere Layers: Facts About the Atmosphere Layers That's almost as wide as Earth itself. Certain birds can fly to this altitude, including cranes, swans, and vultures. The stratosphere is composed primarily of nitrogen and oxygen. The stratosphere ends where it transitions to the mesosphere, around 50 kilometers above the earth. The coldest temperatures in Earths atmosphere, about -90 C (-130 F), are found near the top of this layer. 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. Stratosphere Facts, Characteristics & Composition | What is the These are generated when cold atmospheric air blends with the hot, humid exhaust. It is the only atmospheric layer where temperature inversion occurs and the region where the ozone layer is situated. The waves and tides influence the flows of air in the stratosphere and can also cause regional heating of this layer of the atmosphere. They are a combination of supercooled water and nitric acid that develop at very low temperatures. This allows the stratosphere to have an increasing temperature with altitude. Ionization takes place in the ionosphere caused by the suns radiation. 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. 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. The air in the stratosphere is about 1000 thinner than the air at sea level in the troposphere. 5. 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. It changes sometimes unpredictably Without the stratosphere, life on Earth would be much different, if not non-existent. They result from ionized particles from the sun striking the upper atmosphere above the poles. 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 . - There are no clouds in the layer, and though . Three Highest Thrill Rides in the World. It is also roughly 35 kilometers (22 miles) thick. Stratosphere Definition & Meaning - Merriam-Webster Ozone is a chemical compound consisting of three oxygen atoms. Stratosphere | NASA Space Place - NASA Science for Kids It is important because it contains the ozone layer, which protects the Earth from harmful UV rays. 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. 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. This increase of temperature with altitude is characteristic of the stratosphere; its resistance to vertical mixing means that it is stratified. Commercial airliners fly in the lower stratosphere to avoid the weather, travel faster, and save fuel. Radicals produced from the homolytically split oxygen molecules combine with molecular oxygen to form ozone. The Earth's atmosphere is a mixture of several gases. Unlike the troposphere, the stratosphere actually gets warmer the higher you go! It not only examines what the stratosphere is but also looks at the characteristics or facts that define it. PSCs appear in the lower stratosphere near the poles in winter. Air circulation within the stratosphere is dominated by the Brewer-Dobson Circulation, which is a single-celled air movement that stretches from the Poles to the Equator. At an altitude of 100 km above sea level, a border represents the separation between the atmosphere and outer space. These gases are chemically inert, although some can react with various chemicals: carbon monoxide, sulfur dioxide, methane, ammonia, ozone, and water vapor. 2 It extends from a height of approximately 65 km (40 miles) to 85 km (53 miles) above the Earth's surface. Polar Stratospheric Clouds develop in this layer near the poles at an altitude of 15 - 25 kilometers. It extends above the tropopause to an altitude of 50 km above the earth. The troposphere, the lowest layer, is right below the stratosphere. Its like a teacher waved a magic wand and did the work for me. Between the troposphere and stratosphere is the tropopause border that demarcates the beginning of the temperature inversion. The word 'stratosphere' is derived from the word 'strato' meaning layer, and 'sphere' which is earth's shape. Layers of the atmosphere: troposphere, stratosphere, mesosphere . The main gases are nitrogen and oxygen, which make up 99% of the atmosphere. What's in the Atmosphere? | NASA Climate Kids Autumn Skies Online Pty Ltd is compensated for referring traffic and business to these companies., The Earth's atmosphere consists of five layers. [20], Some bird species have been reported to fly at the upper levels of the troposphere. UCAR/Randy Russell But its not the same everywhere. Unlike the troposphere, it contains little water vapor so there are no clouds in this layer of the atmosphere. It occurs naturally in small (trace) amounts in the upper atmosphere (the stratosphere). 14. Like an onion, the Earth's atmosphere is composed of many layers. The lower boundary of the stratosphere is called the tropopause; the upper boundary is called the stratopause. This list does not contain all the data available about the stratosphere but highlights the key facts and characteristics of this layer. The mesosphere is directly above the stratosphere and below the thermosphere. These "blue jets" appear above thunderstorms, and extend from the bottom of the stratosphere up to altitudes of 40 or 50 km (25 to 31 miles). Stratosphere | atmospheric region | Britannica 20. Some researchers and even students have sent helium balloons with cameras to record the stratosphere. This UV radiation is important for the production of vitamin D in humans, but too much can destroy tissue. The stratosphere is where youll find the very important ozone layer. 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. Of all the atmospheric layers, this is the most closest to the Earth. It is the only atmospheric layer where temperature inversion occurs and the region where the ozone layer is situated. It acts as a giant sponge and absorbs the vast majority of the sun's dangerous Ultraviolet Light. Life as we know it wouldnt be possible without this layer of protection. (The ozone layer is too large a topic for this article, but you can read more about it in the following post.). It helps in propagation of the radio waves used in telecommunication. As a meteor begins to enter this layer, it rapidly bumps into mesosphere particles and scrapes against them. The amount of water vapour in the stratosphere is very low, and because of this there are no clouds in the stratosphere.
