Strat means layer. This UV radiation is important for the production of vitamin D in humans, but too much can destroy tissue. Sydney Chapman gave a correct description of the source of stratospheric ozone and its ability to generate heat within the stratosphere;[citation needed] he also wrote that ozone may be destroyed by reacting with atomic oxygen, making two molecules of molecular oxygen. These are generated when cold atmospheric air blends with the hot, humid exhaust. The atmosphere is dense near the surface of the Earth and protects life on the planet Earth. [12] Eustace also broke the world records for vertical speed skydiving, reached with a peak velocity of 1,321km/h (822mph) and total freefall distance of 123,414ft (37,617m) lasting four minutes and 27 seconds.[13]. It acts as a giant sponge and absorbs the vast majority of the sun's dangerous Ultraviolet Light. Temperatures rise as one moves upward through the stratosphere. It not only examines what the stratosphere is but also looks at the characteristics or facts that define it. It keeps us warm, gives us oxygen to breathe, and it is where our weather happens. The infamous ozone layer is found within the stratosphere. It contains 80% of the atmospheric weight, making it the densest layer. The stratosphere is one of five layers of the earth's atmosphere. The stratosphere is one of five layers of the earth's atmosphere. The stratosphere is located above the troposphere and below the mesosphere. Earths atmosphere is similar to a jacket for our planet. Airplanes fly in the stratosphere to avoid turbulence. Thats the opposite of how the layers work in the troposphere, where we live. This ozone layer is important for man's survival, and for the survival of life on earth, as it absorbs the UV radiation from the sun that would otherwise be deadly. This is due to the temperature changes within the stratosphere. Clouds form due to convection, which is uncommon in the stratosphere. The stratosphere was discovered in 1900 by French meteorologist Lon Teisserenc de Bort. It borders the troposphere below through a thin transitional space called the tropopause. As a result of the EUs General Data Protection Regulation (GDPR). It is also roughly 35 kilometers (22 miles) thick. Despite Mercury's weak magnetic field, it behaves similarly to Earth's. This is just an estimate, however, as the lower and upper boundaries actually vary with the latitude of the earth. 8. It changes sometimes unpredictably This list does not contain all the data available about the stratosphere but highlights the key facts and characteristics of this layer. This layer of our atmosphere has its own set of layers. Scientists have been warning people for many years about the damage we are doing to the ozone layer. Without it, the earths surface would be so cold that living here would not be possible. 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 stratosphere contains the ozone layer, which shields the Earth from harmful radiation emitted from the Sun. Composition of the Earth's atmosphere. Learn about the stratosphere, including the stratosphere's definition and importance. The stratosphere extends from the tropopause at about 10 to 17 km (about 6 to 11 miles) altitude to its upper boundary (the stratopause) at . 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. It is the second layer of the atmosphere as you go upward. Stratospheric circulation is a predominantly wave-driven circulation in that the tropical upwelling is induced by the wave force by the westward propagating Rossby waves, in a phenomenon called Rossby-wave pumping. . Stratosphere | Encyclopedia.com "Strat" means layer. There are a few other atmospheric layers as well -- you can take a look at a diagram of these below. Life as we know it wouldnt be possible without this layer of protection.

The next higher layer above the stratosphere is the mesosphere. It is the second layer of the atmosphere as you go upward. Three Highest Thrill Rides in the World. Moreover, meteorites falling over the earth burn in this layer. It lies above the troposphere, the layer closest to Earth, and below the mesosphere. Temperature decreases with height throughout the mesosphere. Most clouds appear here, mainly because 99% of the water vapor in the atmosphere is found in the troposphere. Stratospheric warming of the polar vortex results in its weakening. Since the stratosphere has increasing temperature with elevation, convection is very rare. stratosphere: [noun] the part of the earth's atmosphere which extends from the top of the troposphere to about 30 miles (50 kilometers) above the surface and in which temperature increases gradually to about 32 F (0 C) and clouds rarely form. Facts About the Atmosphere - Overview, Benefits and Its Layers Almost all weather is in this region. The stratosphere is a very interesting layer in Earth's atmosphere, as there are many fun stratosphere facts outside of its primary characteristics that make it unique. stratosphere, layer of Earth's atmosphere lying between the troposphere and the mesosphere. They result from ionized particles from the sun striking the upper atmosphere above the poles. Certain bird species like the common crane, whooper swan, and the Rppel's griffon vulture are capable of flying in the lower stratosphere. The stratosphere the atmosphere's second layer, and is located right above the troposphere and right below the mesosphere. 16. 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 photosynthesis process enables plants to take up carbon dioxide and release oxygen into the atmosphere. Heat is produced in the process of the formation of Ozone, and this heat is responsible for . In this region, the temperature increases with height. The atmosphere comprises five layers: troposphere, stratosphere, mesosphere, thermosphere and exosphere. copyright 2003-2023 Study.com. As you rise through the troposphere, the temperature decreases to around -60 degrees Fahrenheit. Its about 6,200 miles (10,000 kilometers) thick. As the altitude increases, the atmosphere diminishes which is the reason why the air pressure in the exosphere is shallow. Variations in the amount of energy coming from the Sun exert a powerful influence on both the height of the top of this layer and the temperature within it. This layer of our atmosphere has its own set of layers. They have been observed by airline pilots and the international space station. However, the air in this layer is so thin that it would feel freezing cold to us! It is the only atmospheric layer where temperature inversion occurs and the region where the ozone layer is situated. That means that to get to outer space, you have to be really far from Earth. What are 3 interesting facts about Mercury? Temperatures in the upper thermosphere can range from about 500 C (932 F) to 2,000 C (3,632 F) or higher. The other four layers include the troposphere, mesosphere, thermosphere, and exosphere. Rainbow Facts: What Is A Rainbow And How Does It Occur? Above the troposphere and below the mesosphere, we have the stratosphere. Since almost almost weather activity is limited to the troposphere and almost no water vapor is present in the stratosphere, Polar Stratospheric Clouds is the only visual meteorological phenomenon that can be observed in the stratosphere. It is easy & understandable to view our atmosphere as a continuous layer of air. Ninety-nine percent of the gases that compose the atmosphere are located below a height of 32 km (20 miles). The air in the stratosphere is extremely thin, which makes it impossible to breathe at this level. Planes and jets will sometimes. This is exactly the opposite of the behavior in the troposphere in which we live, where temperatures drop with increasing altitude. 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. The ozone layer lies in the stratosphere, which absorb the majority of harmful UV radiation from the sun. [6] Winds in the stratosphere can far exceed those in the troposphere, reaching near 60m/s (220km/h; 130mph) in the Southern polar vortex. Earth is a great planet to live on because it has a wonderful atmosphere around it. We take a closer look at the stratosphere and its defining characteristics. The troposphere is the lowest layer of our atmosphere. 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. Ozone layer | Description, Importance, & Facts | Britannica It is in the thermosphere that the space shuttle flew. It surrounds the globe and protects it by absorbing the infrared rays from the sun. 34. The stratosphere is the second layer of the atmosphere, in between the troposphere and the mesosphere. Ozone is a blue pungent-smelling gas that helps to absorb the ultraviolet radiation in the sun rays. 10. Also, magnetic and south poles reverse at uneven intervals of hundreds of thousands of years. The exosphere gradually fades away into the realm of interplanetary space. 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. Ozone layer lies about 19-32 km over the earths surface. 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. 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. Atmosphere | NASA Climate Kids 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. [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. 5. She earned her bachelor's in Physics and Astronomy from the University of North Carolina at Asheville. Just above that is the stratosphere, the area of the atmosphere where passenger airplanes and weather balloons fly. That's almost as wide as Earth itself. Fun Stratosphere Facts for Kids. As it absorbs the UV light, it absorbs energy. It is the only atmospheric layer where temperature inversion takes place. Its like a teacher waved a magic wand and did the work for me. Earth's atmosphere has a series of layers, each with its own specific traits. Each year, this large amount of water is recycled about 40 times. In the stratosphere - 'strato' means layer and sphere is the shape of the earth. 9. Of all the atmospheric layers, this is the most closest to the Earth. Within no time, the vapor from the exhaust freezes and turns visible. Radicals produced from the homolytically split oxygen molecules combine with molecular oxygen to form ozone. It also consists of a layer known as the ozone layer, a blanket of ozone that absorbs harmful ultraviolet (UV) rays from the sun. 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.
