10 Things to Know About the Ionosphere - NASA Solar System Exploration 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 mesosphere is the third layer of the atmosphere (above the troposphere and stratosphere.) Because the temperature in the tropopause and lower stratosphere is largely constant with increasing altitude, very little convection and its resultant turbulence occurs there. 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. It has a very important job: to protect us from harmful energy from the Sun, called radiation. They result from ionized particles from the sun striking the upper atmosphere above the poles. Facts About The Stratosphere: What It Is And Its Defining Characteristics [21] Bar-headed geese (Anser indicus) sometimes migrate over Mount Everest, whose summit is 8,848m (29,029ft). The holes in the ozone layer have been recorded above the Antarctica seasonally, as well as in other parts of the world. 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. Radicals produced from the homolytically split oxygen molecules combine with molecular oxygen to form ozone. Facts About the Stratosphere Tower | USA Today Around the poles, it actually begins at around 7 kilometers, whereas around the equator it can be as high as 20 kilometers. 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. Its about 6,200 miles (10,000 kilometers) thick. Be grateful! Ozone layer lies about 19-32 km over the earths surface. The ozone layer is very important, as it protects life on Earth from the majority of the UV rays emitted from the sun. It is the only layer of the atmosphere where temperature inversion occurs. Polar Stratospheric Clouds develop in this layer near the poles at an altitude of 15 - 25 kilometers. PSCs appear in the lower stratosphere near the poles in winter. 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. "Strat" means layer. The rides, which are called The Big Shot, Insanity and X-Scream, are equally terrifying and exciting. 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. 12 chapters | 34. Above the troposphere and below the mesosphere, we have the stratosphere. The air in the mesosphere is far too thin to breathe (the air pressure at the bottom of the layer is well below 1% of the pressure at sea level and continues dropping as you go higher). Solar ultraviolet radiation (sunlight) separates an oxygen molecule into two different oxygen atoms in the first step. It also allows the airplane to stay above the turbulent weather of the troposphere. The next higher layer above the stratosphere is the mesosphere. Unlike the troposphere however it is colder closer to the earth and warmer as it gets closer to the mesosphere. It starts to glow, and the rocks begin to fly off. That's almost as wide as Earth itself. A single chlorine atom can destroy more than a hundred thousand ozone molecules. 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. Skin cancer frequency is increasing due to the thinning of the ozone layer. 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. It is the only atmospheric layer where temperature inversion takes place. 77 Amazing, Interesting, and Exciting Facts about the Atmosphere These distances vary slightly due to elevation changes on the Earth. Exosphere | NASA Space Place - NASA Science for Kids Thermosphere | NASA Space Place - NASA Science for Kids Like an onion, the Earth's atmosphere is composed of many layers. Troposphere - The lowest level of our atmosphere is called the Troposphere. Atmosphere facts: ninety-nine percent of the gases that compose the atmosphere are located below a height of 32 km (20 miles). Autumn Skies Online Pty Ltd is a participant in the Amazon Services LLC Associates Program, an affiliate advertising program designed to provide a means for sites to earn advertising fees by advertising and linking to Amazon.com. Due to the characteristics of the stratosphere, it is a very important part of Earth's atmosphere. The stratosphere is the second layer of the atmosphere. Once you leave the stratosphere, and enter the mesosphere, the temperature dramatically decreases until plummeting to around -184 degrees Fahrenheit. The Stratosphere | Center for Science Education The troposphere, the lowest layer, is right below the stratosphere. The exosphere gradually fades away into the realm of interplanetary space. She earned her bachelor's in Physics and Astronomy from the University of North Carolina at Asheville. These are generated when cold atmospheric air blends with the hot, humid exhaust. [6], The mechanism describing the formation of the ozone layer was described by British mathematician Sydney Chapman in 1930. (The fuel consumption depends on the drag, which is related to the lift by the lift-to-drag ratio.) Temperatures in the upper thermosphere can range from about 500 C (932 F) to 2,000 C (3,632 F) or higher. Various types of waves and tides in the atmosphere influence the stratosphere. In this region, the temperature increases with height. The more humid the atmosphere is, the thicker the contrails will be. 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. Discover fun facts about the stratosphere and stratosphere characteristics. Exosphere widely contains particles of helium and hydrogen. 9. Luckily the situation has improved since the ban of chlorofluorocarbon. What are the characteristics of stratosphere? Also, magnetic and south poles reverse at uneven intervals of hundreds of thousands of years. The stratosphere (/strtsfr, -to-/) is the second layer of the atmosphere of the Earth, located above the troposphere and below the mesosphere. This layer of our atmosphere has its own set of layers. It is the second layer of the atmosphere as you go upward. The stratosphere has many defining features that make it a unique part of the atmosphere. Commercial airliners fly in the lower stratosphere to avoid the weather, travel faster, and save fuel. (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.). https://en.wikipedia.org/w/index.php?title=Stratosphere&oldid=1140010063, This page was last edited on 18 February 2023, at 00:23. The burning of fossil fuels discharges carbon dioxide, while agricultural developments deposit a lot of methane and nitrogen oxides into the atmosphere. 32. Above the stratosphere is the mesosphere. Each year, this large amount of water is recycled about 40 times. 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. Finally, chlorofluorocarbon molecules are photolysed in the stratosphere releasing chlorine atoms that react with ozone giving ClO and O2. It borders the mesosphere above through a thin transitional space called the stratopause. 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. Stratosphere Facts, Characteristics & Composition | What is the There is no clear-cut upper boundary where the exosphere finally fades away into space. I feel like its a lifeline. The stratosphere also has an increasing temperature with increasing altitude, which is different than what happens in the troposphere. "Strat" means layer. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. The atmosphere is dense near the surface of the Earth and protects life on the planet Earth. The stratosphere is located above the troposphere and below the mesosphere. These free-moving elements continuously escape into space due to ballistic trajectories. Here are 50 Interesting facts about the atmosphere that you probably didnt know. The stratosphere contains approximately 19% of the earth's total atmospheric gases. Earth's atmosphere is similar to a jacket for our planet. Biosphere forms part of the troposphere where life exists. [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 . 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. Bacterial life survives in the stratosphere, making it a part of the biosphere. The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high (5 to 9 miles). 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. The stratosphere ( / strtsfr, - to -/) is the second layer of the atmosphere of the Earth, located above the troposphere and below the mesosphere. But its not the same everywhere. [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. Interestingly, the most significant portion of the atmosphere is located within twelve kilometers of the earths surface. The stratosphere is a layer of Earths atmosphere. The composition of the atmosphere of each celestial body is different. Certain swans, cranes, and vultures can fly in the lower stratosphere. Stratospheric warming of the polar vortex results in its weakening. Stratosphere | Encyclopedia.com This border is known as the Karman line. The ozone layer is a layer of gas within the stratosphere that protects the Earth's surface from harmful ultraviolet sun rays. 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 stratosphere is situated just above the troposphere, with a thin layer of air called the tropopause separating the two layers. Earths atmosphere has six layers: the troposphere, the stratosphere, the mesosphere, the thermosphere, the ionosphere, and the exosphere. Certain bird species like the common crane, whooper swan, and the Rppel's griffon vulture are capable of flying in the lower stratosphere. Blue jets are an extremely rare form of lightning or electrical discharge from clouds in the troposphere. In this article, we are going to learn about the atmosphere. Most airplanes or jets travel in the lower part of the stratosphere. This UV radiation is important for the production of vitamin D in humans, but too much can destroy tissue. 20. The resultant breaking causes large-scale mixing of air and other trace gases throughout the midlatitude surf zone. Almost all weather is in this region. Earth's atmosphere has a series of layers, each with its own specific traits. The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high. Other gases that make up the remaining 0.1 percent include trace amounts of carbon dioxide, methane, water vapour, and neon. The lack of particles in the air causes less friction to hold an aircraft back, which requires less power to travel faster and further. Starting at ground level, it extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level.

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). The atmosphere is about 500 km thick, with a mix of more than ten different gases. 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. [20], Some bird species have been reported to fly at the upper levels of the troposphere. It acts as a giant sponge and absorbs the vast majority of the sun's dangerous Ultraviolet Light. The stratosphere is the second layer of the Earth's atmosphere, laying just above the troposphere and below the mesosphere. 3 It borders the stratosphere below through a thin transitional space called the stratopause. 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. Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. 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 increase of temperature with altitude is characteristic of the stratosphere; its resistance to vertical mixing means that it is stratified. OH is formed by the reaction of electrically excited oxygen atoms produced by ozone photolysis, with water vapor. It's about 6,200 miles (10,000 kilometers) thick. Layers of the Atmosphere | National Oceanic and Atmospheric Administration 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). 50 Interesting Facts About The Atmosphere - Page 2 of 3 - The Fact File The oxygen atom product combines with atmospheric molecular oxygen to reform O3, releasing heat. This layer of our atmosphere has its own set of layers. 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. For years, CFCs - a chemical used in aerosols - were transported the stratosphere via convection and became trapped there. 19. This is just an estimate, however, as the lower and upper boundaries actually vary with the latitude of the earth. The stratosphere is one of five layers of the earth's atmosphere. 21. When the ozone absorbs ultraviolet radiation, it actually causes another phenomenon that is used to identify different layers in the atmosphere. However, the distance of 100 kms from the earths surface is what is considered generally as an imaginary boundary. 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. One of the most surprising things about the stratosphere is not its characteristics but about what you find in this layer. Convection is when gases cool as they rise, allowing them to condense on air molecules which form clouds. Convection is when gasses cool down as they rise, allowing them to condense onto air particles and form clouds. The greenhouse gases increase the effect making the earths surface to be warmer than usual. They are far much apart from that they can move thousands of kilometers without colliding. 30. Hare, J.R. Knight. 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. However, the air in this layer is so thin that it would feel freezing cold to us! Planting trees is one of the efforts that people have done to try to minimize damage and to help rebuild the damaged ozone layer. 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.
