A.A. Scaife, J.R. Knight, G.K. Vallis, C.K. 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. 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. Dr. Rachel Tustin has a PhD in Education focusing on Educational Technology, a Masters in English, and a BS in Marine Science. Radicals produced from the homolytically split oxygen molecules combine with molecular oxygen to form ozone. 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). It has a very important job: to protect us from harmful energy from the Sun, called radiation. The stratosphere has many defining features that make it a unique part of the atmosphere. 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]. It is enough to cover the entire earths surface with 1 cm of rain. The coldest temperatures in Earths atmosphere, about -90 C (-130 F), are found near the top of this layer. This jacket of gases does a lot for us. The jet stream flows near the border between the troposphere and the stratosphere. Since the stratosphere has increasing temperature with elevation, convection is very rare. As the ozone layer absorbs UV radiation, it causes the temperature in this layer to increase. While common in the troposphere, very little convection takes place in the stratosphere. Convection is when gasses cool down as they rise, allowing them to condense onto air particles and form clouds. Create an account to start this course today. There are little to no clouds in the stratosphere from the lack of convection. [20], Some bird species have been reported to fly at the upper levels of the troposphere. 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. Clouds rarely form in the stratosphere for this reason as well, as the air is very dry. Certain birds can fly to this altitude, including cranes, swans, and vultures. 11. Due to the characteristics of the stratosphere, it is a very important part of Earth's atmosphere. Of all the atmospheric layers, this is the most closest to the Earth. Just like the troposphere, its depth varies with latitude. Various types of waves and tides in the atmosphere influence the stratosphere. 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. Most of the clouds form in the troposphere, just below the stratosphere. The rapid photolysis and reformation of ozone heat the stratosphere, resulting in a temperature inversion. Gases and dust from volcanic eruptions often meet the same fate, remaining trapped in the stratosphere for months or even longer. The stratosphere is located above the troposphere and below the mesosphere. Earth's Atmosphere | NASA Space Place - NASA Science for Kids 35. The Earth's atmosphere is very important, as each layer plays a role for life on Earth. 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. Above the troposphere and below the mesosphere, we have the stratosphere. These events often precede unusual winter weather [16] and may even be responsible for the cold European winters of the 1960s.[17]. You might have seen planes leaving white condensation trails. The stratosphere also traps certain gasses known as CFC's, which are chemicals derived from aerosol. Stratosphere is the second layer. This layer is 22 miles (35 kilometers) thick. What's in the Atmosphere? | NASA Climate Kids 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). Layers of the atmosphere: troposphere, stratosphere, mesosphere . Despite Mercury's weak magnetic field, it behaves similarly to Earth's. 6. Earth's Atmospheric Layers | NASA . 4. As previously mentioned, the stratosphere is one of the five layers that make up the Earth's atmosphere. The other four layers include the troposphere, mesosphere, thermosphere, and exosphere. He discovered this atmospheric layer by sending a weather balloon up and noticing that the temperature changes differently than it does in the troposphere. Exosphere widely contains particles of helium and hydrogen. It extends upward to a height of about 85 km (53 miles) above our planet. The stratosphere is a layer of Earth's atmosphere. When the ozone absorbs ultraviolet radiation, it actually causes another phenomenon that is used to identify different layers in the atmosphere. This is just an estimate, however, as the lower and upper boundaries actually vary with the latitude of the earth. The stratosphere was discovered in 1900 by French meteorologist Lon Teisserenc de Bort. Thislayerseparates the rest of the atmosphere from outer space. As you rise through the troposphere, the temperature decreases to around -60 degrees Fahrenheit. (The fuel consumption depends on the drag, which is related to the lift by the lift-to-drag ratio.) [22][23], In 1902, Lon Teisserenc de Bort from France and Richard Assmann from Germany, in separate but coordinated publications and following years of observations, published the discovery of an isothermal layer at around 1114km, which is the base of the lower stratosphere. The image above illustrates the layers of Earth's atmosphere and their approximate distances from the Earth's surface. The stratosphere is one of five layers of the earth's atmosphere. It borders the mesosphere above through a thin transitional space called the stratopause. 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. What are 3 interesting facts about Mercury? This decrease in temperature with altitude is what causes convection to occur in the troposphere. The importance of the stratosphere is highlighted by the presence of the ozone layer, without which no life on Earth will be possible. 29. The stratosphere ( / strtsfr, - to -/) is the second layer of the atmosphere of the Earth, located above the troposphere and below the mesosphere. The troposphere is where we breath in and is also referred to as the lower atmosphere. This list does not contain all the data available about the stratosphere but highlights the key facts and characteristics of this layer. A rare type of electrical discharge, somewhat akin to lightning, occurs in the stratosphere. 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 the second layer in the Earth's atmosphere. However, exceptionally energetic convection processes, such as volcanic eruption columns and overshooting tops in severe supercell thunderstorms, may carry convection into the stratosphere on a very local and temporary basis. The troposphere is the lowest layer of our atmosphere. It surrounds our planet, keeps us warm, gives us oxygen to breathe, and it is where our weather happens. Layers of the atmosphere: troposphere, stratosphere, mesosphere and thermosphere. However, as you enter the stratosphere, the ozone gas absorbs the ultraviolet light entering the atmosphere from the sun. 77 Amazing, Interesting, and Exciting Facts about the Atmosphere Most clouds appear here, mainly because 99% of the water vapor in the atmosphere is found in the troposphere. Polar stratospheric clouds (PSCs) are the exception. All other trademarks and copyrights are the property of their respective owners. Rocket launches inject exhaust gases into the stratosphere, producing uncertain consequences. Unlike the troposphere however it is colder closer to the earth and warmer as it gets closer to the mesosphere. The lower portion of the stratosphere is nearly isothermal (a layer of constant temperature), whereas temperatures in its upper levels increase with altitude. Unlike the troposphere, it contains little water vapor so there are no clouds in this layer of the atmosphere. The stratosphere extends from the top of the troposphere to about 50 km (31 miles) above the ground. The stratosphere ends where it transitions to the mesosphere, around 50 kilometers above the earth. Between the troposphere and stratosphere is the tropopause border that demarcates the beginning of the temperature inversion. Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. Ozone (O3) photolysis produces O and O2. It extends above the tropopause to an altitude of 50 km above the earth. He concluded that there was another layer in the atmosphere above the troposphere, which he called the stratosphere. 14. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. The air in the stratosphere is about 1000 thinner than the air at sea level in the troposphere. To learn more about each layer of the atmosphere, click the images below. 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. I feel like its a lifeline. Stratosphere Definition & Meaning - Merriam-Webster It sets it apart from the other atmospheric layers by temperature rising instead of dropping as altitude increases, a process called temperature inversion. This includes its location, what it is composed of, the temperature range, and its density. The main gases are nitrogen and oxygen, which make up 99% of the atmosphere. It starts to glow, and the rocks begin to fly off. The Stratosphere | Center for Science Education It keeps us warm, gives us oxygen to breathe, and it is where our weather happens. The aurora, the Northern Lights and Southern Lights, occur in the thermosphere. The stratosphere contains the ozone layer, which shields the Earth from harmful radiation emitted from the Sun. These free-moving elements continuously escape into space due to ballistic trajectories. [21] Bar-headed geese (Anser indicus) sometimes migrate over Mount Everest, whose summit is 8,848m (29,029ft). It has different layers with different qualities. It is the only atmospheric layer where temperature inversion occurs and the region where the ozone layer is situated. 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. Troposphere. 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. Luckily the situation has improved since the ban of chlorofluorocarbon. Discover fun facts about the stratosphere and stratosphere characteristics. Atmosphere facts: ninety-nine percent of the gases that compose the atmosphere are located below a height of 32 km (20 miles). This breaking is much more pronounced in the winter hemisphere where this region is called the surf zone. 2. 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. It changes sometimes unpredictably The shiny blue marble continues to fascinate us since the time we began walking across its surfaces. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. Troposphere - The lowest level of our atmosphere is called the Troposphere. [7] Molecular oxygen absorbs high energy sunlight in the UV-C region, at wavelengths shorter than about 240nm. Planes fly in the stratosphere to avoid turbulence and fly longer distances using less fuel. 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. This allows the stratosphere to have an increasing temperature with altitude. PSCs are also called nacreous clouds. Air density is the lowest, and its temperature can increase up to 1500 degrees Celsius. The latter value is about halfway to the Moon!

One of the most surprising things about the stratosphere is not its characteristics but about what you find in this layer. N.Butchart, A.A. Scaife, J. Austin, S.H.E. Troposphere is the thinnest and closest layer to the earths surface. - Structure, Solubility & Products, Arrow Pushing Mechanism in Organic Chemistry, Topicity in Stereochemistry: Relationships & Examples, Antarafacial & Suprafacial Relationships in Organic Chemistry, Working Scholars Bringing Tuition-Free College to the Community. The photosynthesis process enables plants to take up carbon dioxide and release oxygen into the atmosphere. 2023 TheFactFile.Org. Stratopause is the connection between the mesosphere and stratosphere. (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.). When greenhouse gases rise into the atmosphere, they form chloride ions that destroy the ozone layer by making holes in it. These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure. It is the reason why the sky appears blue. As altitude increases, air density in the layers of the atmosphere decrease. It is the second layer of the atmosphere as you go upward. 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 greenhouse gases increase the effect making the earths surface to be warmer than usual. 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. Above the stratosphere is the mesosphere. The next higher layer above the stratosphere is the mesosphere. Fun Stratosphere Facts for Kids. Current map of global winds and temperatures at the 10 hPa level. 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. 5. This border is known as the Karman line. It also allows the airplane to stay above the turbulent weather of the troposphere. No tracking or performance measurement cookies were served with this page. 24. 4 [6], The mechanism describing the formation of the ozone layer was described by British mathematician Sydney Chapman in 1930. 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. On October 24, 2014, Alan Eustace became the record holder for reaching the altitude record for a manned balloon at 135,890ft (41,419m). 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. 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. This layer is 22 miles (35 kilometers) thick. 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. As a meteor begins to enter this layer, it rapidly bumps into mesosphere particles and scrapes against them. Facts About The Mesosphere - What It Is And Its Defining Characteristics The ozone layer lies in the stratosphere, which absorb the majority of harmful UV radiation from the sun. Earths atmosphere is similar to a jacket for our planet. The temperatures in the ozone belt are higher than in the troposphere since the ozone absorbs the ultraviolet rays. Ozone protects life on Earth from the Sun's ultraviolet (UV) radiation. [4] Temperatures range from an average of 51C (60F; 220K) near the tropopause to an average of 15C (5.0F; 260K) near the mesosphere. Atmosphere | NASA Climate Kids [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. It is easy & understandable to view our atmosphere as a continuous layer of air. Hare, J.R. Knight. They shoot upwards through the stratosphere in a blue column to altitudes as high as 50km! It is important because it contains the ozone layer, which protects the Earth from harmful UV rays. This article focus on the stratosphere, Earth's second layer. These distances vary slightly due to elevation changes on the Earth. https://en.wikipedia.org/w/index.php?title=Stratosphere&oldid=1140010063, This page was last edited on 18 February 2023, at 00:23. 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. The atmosphere surrounds our planet like the peel of an orange. 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. A two-step reactive mechanism produces ozone in the stratosphere naturally.
