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 mesosphere is directly above the stratosphere and below the thermosphere. Louise Fisher has taught middle school students introductory physics topics for two years. Air is roughly a thousand times thinner at the top of the stratosphere than it is at sea level. Certain bird species like the common crane, whooper swan, and the Rppel's griffon vulture are capable of flying in the lower stratosphere. Because of this, jet aircraft and weather balloons reach their maximum operational altitudes within the stratosphere. 1. As it absorbs the UV light, it absorbs energy. Moreover, the distance between the molecules increases as you move up the different layers. It is the only atmospheric layer where temperature inversion takes place. Providing an environment conducive to good instruction and motivation in which there is an atmosphere of self-motivation and self-discipline in the areas of personal development, character, and academic integrity. If you are interested in the complete structure and make-up of the atmosphere,this articlecovers all five atmospheric layers and their relation to each other in more detail. 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. The stratosphere is one of five layers of the earth's atmosphere. Thus it means layer which surrounds the earth. Ozone is important for ensuring that just the right amount of ultraviolet radiation reaches the earth. Some of these waves and tides carry energy from the troposphere upward into the stratosphere, others convey energy from the stratosphere up into the mesosphere. Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. When greenhouse gases rise into the atmosphere, they form chloride ions that destroy the ozone layer by making holes in it. 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. It is located just above the troposphere, which is the first layer of the atmosphere closest to the ground. The stratosphere is where youll find the very important ozone layer. It lies above the troposphere, the layer closest to Earth, and below the mesosphere. The ozone layer, which absorbs and scatters the . The particles in this layer are electrically charged, and when they hit each other, aurora australis can be observed. As a meteor begins to enter this layer, it rapidly bumps into mesosphere particles and scrapes against them. She has taught in K-12 for more than 15 years, and higher education for ten years. This UV radiation is important for the production of vitamin D in humans, but too much can destroy tissue. The ozone layer is a layer of gas within the stratosphere that protects the Earth's surface from harmful ultraviolet sun rays. Planes and jets will sometimes. However, it is made up out of five different layers: The troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Exosphere widely contains particles of helium and hydrogen. Strat means layer. Certain birds can fly to this altitude, including cranes, swans, and vultures. The ozone layer is within the stratosphere, which protect the Earth from harmful radiation emitted by the sun. The stratosphere is the second layer in the Earth's atmosphere. Its like a teacher waved a magic wand and did the work for me. The timescale of this rapid mixing is much smaller than the much slower timescales of upwelling in the tropics and downwelling in the extratropics. The atmosphere gradually changes as the climate and weather change. She currently works as a physicist assistant at a cancer treatment center. Ozone protects life on Earth from the Sun's ultraviolet (UV) radiation. Thislayerseparates the rest of the atmosphere from outer space. It is seen in high latitude areas as shimmering curtains of lights that are visible at night. Airplanes fly in the stratosphere to avoid turbulence. 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. All air entering the stratosphere must pass through the tropopause, the temperature minimum that divides the troposphere and stratosphere. This is how certain gases become trapped in the stratosphere, like CFC's and ozone. The rides, which are called The Big Shot, Insanity and X-Scream, are equally terrifying and exciting. 3. Temperatures rise as one moves upward through the stratosphere. These distances vary slightly due to elevation changes on the Earth. 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. It is enough to cover the entire earths surface with 1 cm of rain. The stratosphere also contains the ozone layer, which absorbs harmful ultraviolet radiation as it enters our atmosphere from the sun. 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. Earths atmosphere has six different layers. This diagram shows some of the features of the stratosphere. We take a closer look at the stratosphere and its defining characteristics. Planes fly in the stratosphere to avoid turbulence and fly longer distances using less fuel. In many ways, the thermosphere is more like outer space than a part of the atmosphere. Such is the case for ozone-destroying chemicals called CFCs (chlorofluorocarbons). It extends above the tropopause to an altitude of 50 km above the earth. It's about 6,200 miles (10,000 kilometers) thick. Temperature decreases with height throughout the mesosphere. 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. Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. It is possible to send research balloons into the stratosphere. The stratosphere extends from from 4 -12 miles (6-20 km) above the Earth's surface to around 31 miles (50 km).

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. The resultant breaking causes large-scale mixing of air and other trace gases throughout the midlatitude surf zone. The thermosphere extends from about 90 km to 500 kmand 1,000 km above our planet. The stratosphere extends from the top of the troposphere to about 50 km (31 miles) above the ground. Meteorological phenomena are limited to the troposphere since they result from the earths rotation and suns radiation on the atmosphere. Despite Mercury's weak magnetic field, it behaves similarly to Earth's. The height of the bottom of the stratosphere varies with latitude and with the seasons. Temperatures in the upper thermosphere can range from about 500 C (932 F) to 2,000 C (3,632 F) or higher. stratosphere, layer of Earth's atmosphere lying between the troposphere and the mesosphere. There is no clear-cut upper boundary where the exosphere finally fades away into space. It is also roughly 35 kilometers (22 miles) thick. The Earth's atmosphere is very important, as each layer plays a role for life on Earth. 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 . Earth is a great planet to live on because it has a wonderful atmosphere around it. The next higher layer above the stratosphere is the mesosphere. 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. The stratosphere is situated just above the troposphere, with a thin layer of air called the tropopause separating the two layers. Interestingly, the most significant portion of the atmosphere is located within twelve kilometers of the earths surface. The overall circulation of the stratosphere is termed as Brewer-Dobson circulation, which is a single-celled circulation, spanning from the tropics up to the poles, consisting of the tropical upwelling of air from the tropical troposphere and the extra-tropical downwelling of air. This part of the atmosphere is the most dense. As this article clearly illustrated, the stratosphere has a crucial role to play in maintaining the atmosphere and all life in it. Ozone (O3) photolysis produces O and O2. Earth's atmosphere has a series of layers, each with its own specific traits. (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.). Commercial airliners typically cruise at altitudes of 912km (30,00039,000ft) which is in the lower reaches of the stratosphere in temperate latitudes. The stratosphere is very dry air and contains little water vapor. 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 main gases are nitrogen and oxygen, which make up 99% of the atmosphere. Atmosphere facts: ninety-nine percent of the gases that compose the atmosphere are located below a height of 32 km (20 miles). It is important because it contains the ozone layer, which protects the Earth from harmful UV rays. The ozone layer absorbs the majority of these rays, shielding life from harmful radiation. The exosphere is the very edge of our atmosphere. 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. OH is formed by the reaction of electrically excited oxygen atoms produced by ozone photolysis, with water vapor. It borders the troposphere below through a thin transitional space called the tropopause. 4. This is the opposite of what happens in the troposphere, where an increasing altitude yields a decrease in temperature. He discovered this atmospheric layer by sending a weather balloon up and noticing that the temperature changes differently than it does in the troposphere. All Rights Reserved. Gases and dust from volcanic eruptions often meet the same fate, remaining trapped in the stratosphere for months or even longer. The infamous ozone layer is found within the stratosphere. However, as you enter the stratosphere, the ozone gas absorbs the ultraviolet light entering the atmosphere from the sun. Dr. Rachel Tustin has a PhD in Education focusing on Educational Technology, a Masters in English, and a BS in Marine Science. As the altitude increases, the atmosphere diminishes which is the reason why the air pressure in the exosphere is shallow. These gases are chemically inert, although some can react with various chemicals: carbon monoxide, sulfur dioxide, methane, ammonia, ozone, and water vapor. Folland. This creates a smoother ride for passengers, as there are few clouds or weather in the stratosphere. This layer is 22 miles (35 kilometers) thick. 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. . Convection is when gases cool as they rise, allowing them to condense on air molecules which form clouds. Other gases such as carbon dioxide, argon, helium, and neon occupy the remaining portion. N.Butchart, A.A. Scaife, J. Austin, S.H.E. The water exists in the form of vapor and invisible to plain eyes. 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 coldest temperatures are found in the mesopause. [5] Stratospheric temperatures also vary within the stratosphere as the seasons change, reaching particularly low temperatures in the polar night (winter). 2. This layer of our atmosphere has its own set of layers. It helps in propagation of the radio waves used in telecommunication. It surrounds the globe and protects it by absorbing the infrared rays from the sun. 8. To learn more about each layer of the atmosphere, click the images below. The stratosphere contains approximately 19% of the earth's total atmospheric gases. Three Highest Thrill Rides in the World. Rocket launches inject exhaust gases into the stratosphere, producing uncertain consequences. Most airplanes or jets travel in the lower part of the stratosphere. That trend of rising temperatures with altitude means that air in the stratosphere lacks the turbulence and updrafts of the troposphere beneath. This allows the stratosphere to have an increasing temperature with altitude. That means that to get to outer space, you have to be really far from Earth. The air has a very low density that you get into the interplanetary space without a manifest limit. 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. This layer of our atmosphere has its own set of layers. It keeps us warm, gives us oxygen to breathe, and it is where our weather happens. [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. 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. 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. Ozone (O3) is a highly reactive gas whose molecules are comprised of three oxygen atoms. PSCs appear in the lower stratosphere near the poles in winter. It borders the mesosphere above through a thin transitional space called the stratopause. Finally, chlorofluorocarbon molecules are photolysed in the stratosphere releasing chlorine atoms that react with ozone giving ClO and O2. Planting trees is one of the efforts that people have done to try to minimize damage and to help rebuild the damaged ozone layer. 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. Almost all weather is in this region. Learn about the stratosphere, including the stratosphere's definition and importance. 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. Unlike the troposphere, it contains little water vapor so there are no clouds in this layer of the atmosphere. Once you leave the stratosphere, and enter the mesosphere, the temperature dramatically decreases until plummeting to around -184 degrees Fahrenheit. - 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?
