Ozone depletion is a major environmental problem because it increases the amount of ultraviolet (UV . 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. 11. As you rise through the troposphere, the temperature decreases to around -60 degrees Fahrenheit. 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. Blue jets are an extremely rare form of lightning or electrical discharge from clouds in the troposphere. Moving upward from ground level, these layers are called the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. She currently works as a physicist assistant at a cancer treatment center. It is important because it contains the ozone layer, which protects the Earth from harmful UV rays. The Earth's atmosphere is a mixture of several gases. Autumn Skies Online Pty Ltd also participates in affiliate programs with Clickbank, CJ, ShareASale, and other sites. However, the air in this layer is so thin that it would feel freezing cold to us! Acid rains form when nitrogen oxide or Sulphur dioxide combines with water vapor in the atmosphere. PSCs appear in the lower stratosphere near the poles in winter. 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 stratosphere is one of five layers of the earth's atmosphere. 2011 UCAR with portions adapted from Windows to the Universe ( 2009 NESTA). Although the sun and other planets have magnetospheres, the earths magnetosphere is the strongest one of all the rocky planets. We take a closer look at the stratosphere and its defining characteristics. The temperatures in the ozone belt are higher than in the troposphere since the ozone absorbs the ultraviolet rays. Because of this, the top of the thermosphere can be found anywhere between 500 and 1,000 km (311 to 621 miles) above the ground. In the stratosphere - 'strato' means layer and sphere is the shape of the earth. To learn more about each layer of the atmosphere, click the images below. Create your account. The stratosphere has many defining features that make it a unique part of the atmosphere. However, as you enter the stratosphere, the ozone gas absorbs the ultraviolet light entering the atmosphere from the sun. But there are no mountains high enough to reach the stratosphere, so you dont have to worry about that. 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 fuel consumption depends on the drag, which is related to the lift by the lift-to-drag ratio.) [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. Earth's atmosphere has six layers: the troposphere, the stratosphere, the mesosphere, the thermosphere, the ionosphere, and the exosphere. 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. However, just above that is an equally important layer called the stratosphere. It is located just above the troposphere, which is the first layer of the atmosphere closest to the ground. It has a very important job: to protect us from harmful energy from the Sun, called radiation. The stratosphere is one of five layers of the atmosphere. This layer of our atmosphere has its own set of layers. Acidic rains destroy plants and animals, and if it reaches rivers and lakes, it destroys all the aquatic life. Learn about the stratosphere, including the stratosphere's definition and importance. Stratosphere - Definition, Functions & Characteristics with Videos - BYJUS 16. 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. 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. Atmosphere Layers: Facts About the Atmosphere Layers The stratosphere also traps certain gasses known as CFC's, which are chemicals derived from aerosol. 3. The atmosphere gradually changes as the climate and weather change. Its about 6,200 miles (10,000 kilometers) thick. The Stratosphere also has three thrill rides at the top. The thinning is most pronounced in the polar regions, especially over Antarctica. Temperature decreases with height throughout the mesosphere. Within no time, the vapor from the exhaust freezes and turns visible. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. Earth's atmosphere has a series of layers, each with its own specific traits. The troposphere is the lowest layer of our atmosphere. Since the stratosphere has increasing temperature with elevation, convection is very rare. It contains most of our Earth's water vapour, and is 78% nitrogen and 21% oxygen. The waves and tides influence the flows of air in the stratosphere and can also cause regional heating of this layer of the atmosphere. The troposphere, the lowest layer, is right below the stratosphere. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. Commercial airliners typically cruise at altitudes of 912km (30,00039,000ft) which is in the lower reaches of the stratosphere in temperate latitudes. 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. Ozone is a chemical compound consisting of three oxygen atoms. Moreover, meteorites falling over the earth burn in this layer. The image above illustrates the layers of Earth's atmosphere and their approximate distances from the Earth's surface. This layer is 22 miles (35 kilometers) thick. The layer of very rare air above the mesosphere is called the thermosphere. Enrolling in a course lets you earn progress by passing quizzes and exams. [24], Seinfeld, J. H., and S. N.(2006), Atmospheric Chemistry and Physics: From Air Pollution to Climate Change 2nd ed, Wiley, New Jersey. This part of the atmosphere is the most dense. Rainbow Facts: What Is A Rainbow And How Does It Occur? The lower portion of the stratosphere is nearly isothermal (a layer of constant temperature), whereas temperatures in its upper levels increase with altitude. The stratosphere is a layer of Earth's atmosphere. Its magnetic field goes up to 60,000 km into space. It is seen in high latitude areas as shimmering curtains of lights that are visible at night. The mesosphere is a layer of Earth's atmosphere. 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 stratosphere is a layer of Earths atmosphere. From space, the earth is seen as a blue halo. It is made up of 78% nitrogen and 21% oxygen. It has different layers with different qualities. The Mesosphere | Center for Science Education The other four layers include the troposphere, mesosphere, thermosphere, and exosphere. Stratosphere - Wikipedia "Strat" means layer. Stated another way, it allows the airliner to fly faster while maintaining lift equal to the weight of the plane. Autumn Skies Online Pty Ltd is compensated for referring traffic and business to these companies., The Earth's atmosphere consists of five layers. Unlike the troposphere however it is colder closer to the earth and warmer as it gets closer to the mesosphere. This is just an estimate, however, as the lower and upper boundaries actually vary with the latitude of the earth. Discover fun facts about the stratosphere and stratosphere characteristics. Unlike the troposphere, the stratosphere actually gets warmer the higher you go! The site owner may have set restrictions that prevent you from accessing the site. Ionosphere plays a vital role in radio signals broadcast on the earths surface. What Causes Air Pollution? Here are 50 Interesting facts about the atmosphere that you probably didnt know. Atmosphere facts: ninety-nine percent of the gases that compose the atmosphere are located below a height of 32 km (20 miles). Interestingly, the most significant portion of the atmosphere is located within twelve kilometers of the earths surface. 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. 2. Three Highest Thrill Rides in the World. This allows the stratosphere to have an increasing temperature with altitude. 3. 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. 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. 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. As harmful UV rays from the sun become absorbed in the ozone layer, this layer heats up. (The ozone layer is too large a topic for this article, but you can read more about it in the following post.). The top of the stratosphere occurs at an altitude of 50 km (31 miles). measured by the humidity of the air. Without the stratosphere, life on Earth would be much different, if not non-existent. If you do your calculations, each water vapor particle spends approximately nine days in the atmosphere.

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. Its concentration in the atmosphere naturally fluctuates depending on seasons and latitudes, but it was . 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). Clouds form when water vapor condenses into a liquid, and with very little water, vapor condensation is virtually impossible. The stratosphere is where youll find the very important ozone layer. It keeps us warm, it gives us oxygen to breathe, and its where our weather happens. The thermosphere is home to the International Space Station as it orbits Earth. 26. [4] Temperatures range from an average of 51C (60F; 220K) near the tropopause to an average of 15C (5.0F; 260K) near the mesosphere. When greenhouse gases rise into the atmosphere, they form chloride ions that destroy the ozone layer by making holes in it. 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. - 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 stratosphere is the second layer of the atmosphere. This border is known as the Karman line. Earths atmosphere has six different layers. (Learn more about Nacreous or Polar Stratospheric Clouds in this article.). The ozone layer lies in the stratosphere, which absorb the majority of harmful UV radiation from the sun. 15. We live in one layer, called the troposphere, where the clouds and most of the water vapor reside. This layer of Earth's atmosphere is about 319 miles (513 kilometers) thick. The amount of water vapour in the stratosphere is very low, and because of this there are no clouds in the stratosphere. 30. To unlock this lesson you must be a Study.com Member. 50 Interesting Facts About The Atmosphere - Page 2 of 3 - The Fact File - This is the second layer of the atmosphere from the surface of the earth, and lies between the troposphere and the mesosphere. Weather balloons also rise up to this level of the atmosphere to collect data without interference of storm clouds. Most of the clouds form in the troposphere, just below the stratosphere. In 1985, they observed a hole in the ozone layer above the Antarctic. 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. stratosphere, layer of Earth's atmosphere lying between the troposphere and the mesosphere. Thats the opposite of how the layers work in the troposphere, where we live. Strat means layer. The atmosphere surrounds our planet like the peel of an orange. 22. The shiny blue marble continues to fascinate us since the time we began walking across its surfaces. 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. Heat is produced in the process of the formation of Ozone, and this heat is responsible for . In the 1900s, Hungarian physicist Theodore von Krmn determined the boundary to be around 50 miles up, or roughly 80 kilometers above sea level. A two-step reactive mechanism produces ozone in the stratosphere naturally. What are 3 interesting facts about Mercury? For years, CFCs - a chemical used in aerosols - were transported the stratosphere via convection and became trapped there. Composed of mostly nitrogen and oxygen, the stratosphere also contains the ozone layer. 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. Earth's Atmosphere | NASA Space Place - NASA Science for Kids 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. This jacket of gases does a lot for us. 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. 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. Privacy Policy The ozone layer is within the stratosphere, which protect the Earth from harmful radiation emitted by the sun. As mentioned in the introduction, certain birds such as cranes, swans, and vultures can fly at this altitude. This includes its location, what it is composed of, the temperature range, and its density. Its like a teacher waved a magic wand and did the work for me. Stratosphere is the second layer. These free-moving elements continuously escape into space due to ballistic trajectories. Convection is when gases cool as they rise, allowing them to condense on air molecules which form clouds. Airplanes fly in the stratosphere to avoid turbulence. The stratosphere is the second layer of the Earth's atmosphere, laying just above the troposphere and below the mesosphere. Above the stratosphere is the mesosphere. The more humid the atmosphere is, the thicker the contrails will be. In many ways, the thermosphere is more like outer space than a part of the atmosphere. As a result of the EUs General Data Protection Regulation (GDPR). 17. It also consists of a layer known as the ozone layer, a blanket of ozone that absorbs harmful ultraviolet (UV) rays from the sun. One of the most surprising things about the stratosphere is not its characteristics but about what you find in this layer. 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. That's the opposite of how the .
