what are 3 facts about the stratosphere3 on 3 basketball tournaments in colorado

As the ozone layer absorbs UV radiation, it causes the temperature in this layer to increase. It is in the thermosphere that the space shuttle flew. However, temperature increases with altitude in the stratosphere, which is opposite from the troposphere. Ozone molecules in this layer absorb high-energy ultraviolet (UV) light from the Sun, converting the UV energy into heat. stratosphere The atmospheric layer above the troposphere, which extends on average from about 10 to 50 km above the Earth's surface. However, the air in this layer is so thin that it would feel freezing cold to us! The mesosphere is a layer of Earth's atmosphere. Since blue light has short wavelengths, it gets reflected more compared to other colors. Facts About The Exosphere: The Outermost Layer Of The Atmosphere. But its not the same everywhere. It is the only atmospheric layer where temperature inversion occurs and the region where the ozone layer is situated. The site owner may have set restrictions that prevent you from accessing the site. Many satellites actually orbit Earth within the thermosphere! 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. 23. 110 lessons. It keeps us warm, it gives us oxygen to breathe, and its where our weather happens. They are found at altitudes of 15 to 25 km (9.3 to 15.5 miles) and form only when temperatures at those heights dip below -78 C. They appear to help cause the formation of the infamous holes in the ozone layer by "encouraging" certain chemical reactions that destroy ozone. Create your account. The ozone layer absorbs the majority of these rays, shielding life from harmful radiation. 3. 26. The stratosphere starts just above the troposphere and extends to 50 kilometers (31 miles) high. Thus it means layer which surrounds the earth. The stratosphere is a layer of Earth's atmosphere. Temperature increases with height until the estimated top of the thermosphere at 500 km. Moreover, the distance between the molecules increases as you move up the different layers. The stratosphere is one of five layers of the earth's atmosphere. It is the only layer of the atmosphere where temperature inversion occurs. 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 stratosphere extends from the top of the troposphere to about 50 km (31 miles) above the ground. She has taught in K-12 for more than 15 years, and higher education for ten years. We live in one layer, called the troposphere, where the clouds and most of the water vapor reside. 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. Thats almost as wide as Earth itself. Most of the clouds form in the troposphere, just below the stratosphere. Also known as Nacreous Clouds, these unique clouds develop near the poles at an altitude of 15 - 25 kilometers (9 - 15 miles) during the winter months. For this reason, humans would not be able to survive at this altitude without being inside of a plane, rocket, or some type of enclosed environment where air density can be regulated. Stratosphere Facts, Characteristics & Composition | What is the 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 mesosphere is directly above the stratosphere and below the thermosphere. It has increased the number of respiratory conditions such as asthma. Just above that is the stratosphere, the area of the atmosphere where passenger airplanes and weather balloons fly. 4. It extends from about 50 to 85 km (31 to 53 miles) above our planet. 2. The thinning is most pronounced in the polar regions, especially over Antarctica. Mercury's magnetic field is different at its poles. Airplanes fly in the stratosphere to avoid turbulence. Earth's atmosphere has six layers: the troposphere, the stratosphere, the mesosphere, the thermosphere, the ionosphere, and the exosphere. Most meteors burn up in the mesosphere. Gases and dust from volcanic eruptions often meet the same fate, remaining trapped in the stratosphere for months or even longer. 11. The top of the stratosphere is called the stratopause, above which the temperature decreases with height. To unlock this lesson you must be a Study.com Member. . 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. 50 Interesting Facts About The Atmosphere - Page 2 of 3 - The Fact File Another large-scale feature that significantly influences stratospheric circulation is the breaking planetary waves[15] resulting in intense quasi-horizontal mixing in the midlatitudes. Exosphere widely contains particles of helium and hydrogen. The stratosphere contains approximately 19% of the earth's total atmospheric gases. The air in the stratosphere is about 1000 thinner than the air at sea level in the troposphere. She earned her bachelor's in Physics and Astronomy from the University of North Carolina at Asheville. Unlike the troposphere however it is colder closer to the earth and warmer as it gets closer to the mesosphere. 12. That's almost as wide as Earth itself. 90% of the ozone layer is found in the stratosphere's upper crust. This creates a smoother ride for passengers, as there are few clouds or weather in the stratosphere. However, it is made up out of five different layers: The troposphere, stratosphere, mesosphere, thermosphere, and exosphere. The QBO induces a secondary circulation that is important for the global stratospheric transport of tracers, such as ozone[14] or water vapor. That's much thicker than the inner layers of the atmosphere, but not nearly as thick as the exosphere. These events often precede unusual winter weather [16] and may even be responsible for the cold European winters of the 1960s.[17]. A rare type of electrical discharge, somewhat akin to lightning, occurs in the stratosphere. All other trademarks and copyrights are the property of their respective owners. Life as we know it wouldnt be possible without this layer of protection. 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. 3 It borders the stratosphere below through a thin transitional space called the stratopause. 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. This breaking is much more pronounced in the winter hemisphere where this region is called the surf zone. When the ozone absorbs ultraviolet radiation, it actually causes another phenomenon that is used to identify different layers in the atmosphere. 22. They are far much apart from that they can move thousands of kilometers without colliding. 2011 UCAR with portions adapted from Windows to the Universe ( 2009 NESTA). To learn more about each layer of the atmosphere, click the images below. This decrease in temperature with altitude is what causes convection to occur in the troposphere. The stratosphere has many defining features that make it a unique part of the atmosphere. Exosphere | NASA Space Place - NASA Science for Kids 16. [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. A two-step reactive mechanism produces ozone in the stratosphere naturally. Because of this, jet aircraft and weather balloons reach their maximum operational altitudes within 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). Between the troposphere and stratosphere is the tropopause border that demarcates the beginning of the temperature inversion. Finally, chlorofluorocarbon molecules are photolysed in the stratosphere releasing chlorine atoms that react with ozone giving ClO and O2. One of the most surprising things about the stratosphere is not its characteristics but about what you find in this layer. 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. Learn about the stratosphere, including the stratosphere's definition and importance. As this article clearly illustrated, the stratosphere has a crucial role to play in maintaining the atmosphere and all life in it. 40 Unbelievable But True Troposphere Facts | Kidadl At Home Show All Free Coloring Pages Free Dot to Dot Printables Free Printable Stencils Funnies Trivia Birthdays Books Creative, Arts & Crafts 3090 Center Green Drive, Boulder, CO 80301, Air pressure drops, and temperatures get colder, as you climb higher in the troposphere, ACOM | Atmospheric Chemistry Observations & Modeling, CISL | Computational & Information Systems, EdEC | Education, Engagement & Early-Career Development, Government Relations & External Engagement. The thermosphere is home to the International Space Station as it orbits Earth. The composition of the atmosphere of each celestial body is different. Approximately 90 percent of the atmosphere's ozone occurs in the stratosphere, the region extending from 10-18 km (6-11 miles) to approximately 50 km (about 30 miles) above Earth's surface. 12 chapters | The stratosphere protects Earth life from extremely harmful UV rays from the sun. 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. There are a few other atmospheric layers as well -- you can take a look at a diagram of these below. The exosphere gradually fades away into the realm of interplanetary space. This layer of our atmosphere has its own set of layers. 1. Because of this, few clouds are found in this layer and almost all clouds occur in the lower, more humid troposphere. https://en.wikipedia.org/w/index.php?title=Stratosphere&oldid=1140010063, This page was last edited on 18 February 2023, at 00:23. This is how certain gases become trapped in the stratosphere, like CFC's and ozone. But there are no mountains high enough to reach the stratosphere, so you dont have to worry about that. As a result, the air in the stratosphere is about 1000 times thinner in the stratosphere than at sea level in the troposphere. Write CSS OR LESS and hit save. 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 a layer of Earths atmosphere. Ozone protects life on Earth from the Sun's ultraviolet (UV) radiation. Due to the characteristics of the stratosphere, it is a very important part of Earth's atmosphere. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. This is the opposite of what happens in the troposphere, where an increasing altitude yields a decrease in temperature. The coldest temperatures in Earths atmosphere, about -90 C (-130 F), are found near the top of this layer. This layer is 22 miles (35 kilometers) thick. [21] Bar-headed geese (Anser indicus) sometimes migrate over Mount Everest, whose summit is 8,848m (29,029ft). Ozone (O3) photolysis produces O and O2. The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high (5 to 9 miles). 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. In fact, the air in the exosphere is constantly - though very gradually - "leaking" out of Earth's atmosphere into outer space. It helps in propagation of the radio waves used in telecommunication. Interestingly, the most significant portion of the atmosphere is located within twelve kilometers of the earths surface.

The oxygen atom product combines with atmospheric molecular oxygen to reform O3, releasing heat. Within no time, the vapor from the exhaust freezes and turns visible. Temperatures rise as one moves upward through the stratosphere. 10 Things to Know About the Ionosphere - NASA Solar System Exploration It borders the mesosphere above through a thin transitional space called the stratopause. It is the only atmospheric layer where temperature inversion takes place. Cred: NASA's Scientific Visualization Studio 3. Air is roughly a thousand times thinner at the top of the stratosphere than it is at sea level. Composed of mostly nitrogen and oxygen, the stratosphere also contains the ozone layer. Earths atmosphere has six layers: the troposphere, the stratosphere, the mesosphere, the thermosphere, the ionosphere, and the exosphere. This is the opposite of what happens in the troposphere, the layer of the atmosphere closest to Earth. The layer made of layers. In comparison, the warmest in the thermosphere. Ionosphere plays a vital role in radio signals broadcast on the earths surface. Acid rains form when nitrogen oxide or Sulphur dioxide combines with water vapor in the atmosphere. Convection is when gases cool as they rise, allowing them to condense on air molecules which form clouds. She currently works as a physicist assistant at a cancer treatment center. Air pressure drops, and temperatures get colder, as you climb higher in the troposphere. It is like a giant magnet and retains high-energy particles, thereby protecting the earth. Also, magnetic and south poles reverse at uneven intervals of hundreds of thousands of years. The stratosphere contains the ozone layer, which shields the Earth from harmful radiation emitted from the Sun.
