In fact, the air in the exosphere is constantly - though very gradually - "leaking" out of Earth's atmosphere into outer space. 35. This layer of our atmosphere has its own set of layers. The stratosphere is very dry air and contains little water vapor. Learn about the stratosphere, including the stratosphere's definition and importance. As harmful UV rays from the sun become absorbed in the ozone layer, this layer heats up. measured by the humidity of the air. The stratosphere is the second layer of the atmosphere, which is composed of a total of five layers. 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. 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. 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. N.Butchart, A.A. Scaife, J. Austin, S.H.E. Just like the troposphere, its depth varies with latitude. 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. What are 3 interesting facts about Mercury? The latter value is about halfway to the Moon! [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. The stratosphere contains approximately 19% of the earth's total atmospheric gases. Cred: NASA's Scientific Visualization Studio 3. As a result, air circulation is not as prevalent in this layer of the atmosphere, making it difficult for some gasses to escape. When greenhouse gases rise into the atmosphere, they form chloride ions that destroy the ozone layer by making holes in it. Almost all weather is in this region. 25. Temperature decreases with height throughout the mesosphere. Despite Mercury's weak magnetic field, it behaves similarly to Earth's. Earth's atmosphere has a series of layers, each with its own specific traits. 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. When the ozone absorbs ultraviolet radiation, it actually causes another phenomenon that is used to identify different layers in the atmosphere. It is in the thermosphere that the space shuttle flew. 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. 3. 10 Things to Know About the Ionosphere - NASA Solar System Exploration 32. It lies above the troposphere, the layer closest to Earth, and below the mesosphere. Like the other atmospheric layers, it does not have a fixed height but starts at an altitude of approximately 10 km(6 miles), extending up to a height of roughly 50 km(30 miles). 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. 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. Its upper edge has maximum ozone concentration, referred to as the ozone belt. Ozone layer facts and information - Environment 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. stratosphere The atmospheric layer above the troposphere, which extends on average from about 10 to 50 km above the Earth's surface. While common in the troposphere, very little convection takes place in the stratosphere. Temperature increases with height until the estimated top of the thermosphere at 500 km. He concluded that there was another layer in the atmosphere above the troposphere, which he called the stratosphere. The rides, which are called The Big Shot, Insanity and X-Scream, are equally terrifying and exciting. - 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. On November 29, 1973, a Rppell's vulture (Gyps rueppelli) was ingested into a jet engine 11,278m (37,000ft) above the Ivory Coast. The wind, which is the air current, is generated when the hot air rises and gets replaced by colder air. The exosphere is really, really big. The jet stream flows near the border between the troposphere and the stratosphere. These free-moving elements continuously escape into space due to ballistic trajectories. The ozone layer, which absorbs and scatters the . All air entering the stratosphere must pass through the tropopause, the temperature minimum that divides the troposphere and stratosphere. The ozone layer helps protect us from ultraviolet radiation (UV) from the sun. All Rights Reserved. Skin cancer frequency is increasing due to the thinning of the ozone layer. 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 stratosphere extends from the top of the troposphere to about 50 km (31 miles) above the ground. Polar Stratospheric Clouds develop in this layer near the poles at an altitude of 15 - 25 kilometers. Earth is a great planet to live on because it has a wonderful atmosphere around it. Louise Fisher has taught middle school students introductory physics topics for two years. As the altitude increases, the atmosphere diminishes which is the reason why the air pressure in the exosphere is shallow. The next layer up is called the stratosphere. [7] Molecular oxygen absorbs high energy sunlight in the UV-C region, at wavelengths shorter than about 240nm. I feel like its a lifeline. They go from the ground all the way to outer space. Blue jets are an extremely rare form of lightning or electrical discharge from clouds in the troposphere. Biosphere forms part of the troposphere where life exists. 5. Above the troposphere and below the mesosphere, we have the stratosphere. The height of the bottom of the stratosphere varies with latitude and with the seasons. One of the most surprising things about the stratosphere is not its characteristics but about what you find in this layer. Ice clouds form in this layer which is visible when lighted from beneath during sunset. The bottom of the stratosphere is around 10 km (6.2 miles or about 33,000 feet) above the ground at middle latitudes. In 1985, they observed a hole in the ozone layer above the Antarctic. Although the sun and other planets have magnetospheres, the earths magnetosphere is the strongest one of all the rocky planets. In the 1900s, Hungarian physicist Theodore von Krmn determined the boundary to be around 50 miles up, or roughly 80 kilometers above sea level. 22. Three Highest Thrill Rides in the World. They have been observed by airline pilots and the international space station. This border is known as the Karman line. The atmosphere comprises five layers: troposphere, stratosphere, mesosphere, thermosphere and exosphere. Privacy Policy 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 of Earth's atmosphere is about 319 miles (513 kilometers) thick. Certain bird species like the common crane, whooper swan, and the Rppel's griffon vulture are capable of flying in the lower stratosphere. This is just an estimate, however, as the lower and upper boundaries actually vary with the latitude of the earth. Though the atmosphere may appear uniform to the naked eye, it is actually similar to a layer cake. However, the distance of 100 kms from the earths surface is what is considered generally as an imaginary boundary. Earths atmosphere is similar to a jacket for our planet. 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. But there are no mountains high enough to reach the stratosphere, so you dont have to worry about that. 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. Write CSS OR LESS and hit save. The stratosphere is the second layer in the Earth's atmosphere. 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. Mesosphere lies between 50-85 km above sea level. Acid rains form when nitrogen oxide or Sulphur dioxide combines with water vapor in the atmosphere. These are generated when cold atmospheric air blends with the hot, humid exhaust. Unlike the troposphere, the stratosphere actually gets warmer the higher you go! 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. So, what does the stratosphere do? 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. 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). The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high (5 to 9 miles). The particles in the exosphere do not behave like gases. 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. Most of the clouds form in the troposphere, just below the stratosphere. As the ozone layer absorbs UV radiation, it causes the temperature in this layer to increase. 12 chapters | The ozone layer is situated within this layer. Stratosphere | NASA Space Place - NASA Science for Kids It not only examines what the stratosphere is but also looks at the characteristics or facts that define it. Its about 6,200 miles (10,000 kilometers) thick. This is exactly the opposite of the behavior in the troposphere in which we live, where temperatures drop with increasing altitude. It is the second layer of the atmosphere as you go upward. Just like the troposphere, its depth varies with latitude. But there are no mountains high enough to reach the stratosphere, so you dont have to worry about that. It extends from about 50 to 85 km (31 to 53 miles) above our planet. 4.

It is enough to cover the entire earths surface with 1 cm of rain. Composed of mostly nitrogen and oxygen, the stratosphere also contains the ozone layer. The HO2 radical produced by the reaction of OH with O3 is recycled to OH by reaction with oxygen atoms or ozone. Facts About The Stratosphere: What It Is And Its Defining Characteristics Dr. Rachel Tustin has a PhD in Education focusing on Educational Technology, a Masters in English, and a BS in Marine Science.

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. She currently works as a physicist assistant at a cancer treatment center. These elements react with toxic gases, salt, smoke, and volcanic ash. The stratosphere was discovered in 1900 by French meteorologist Lon Teisserenc de Bort. Earth's Atmosphere | NASA Space Place - NASA Science for Kids To learn more about each layer of the atmosphere, click the images below.

Unlike the troposphere however it is colder closer to the earth and warmer as it gets closer to the mesosphere. "Strat" means layer. The stratosphere accounts for approximately 24% of the earth's total atmosphere. It is important because it contains the ozone layer, which protects the Earth from harmful UV rays. 90% of the ozone layer is found in the stratosphere's upper crust. What's in the Atmosphere? Stratosphere - Definition, Functions & Characteristics with Videos - BYJUS Many satellites actually orbit Earth within the thermosphere! 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. The stratosphere is a layer of extremely stratified air that rises 40 kilometres above the tropopause and comprises about 20% of the atmosphere's mass. 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). The other four layers include the troposphere, mesosphere, thermosphere, and exosphere. Moreover, the distance between the molecules increases as you move up the different layers. However, temperature increases with altitude in the stratosphere, which is opposite from the troposphere. This article focus on the stratosphere, Earth's second layer. As a result of the EUs General Data Protection Regulation (GDPR). Ozone, an unusual type of oxygen molecule that is relatively abundant in the stratosphere, heats this layer as it absorbs energy from incoming ultraviolet radiation from the Sun. At the top of the stratosphere, the density of the air is close to zero. [4] The temperature inversion is in contrast to the troposphere, near the Earth's surface, where temperature decreases with altitude. The mesosphere is directly above the stratosphere and below the thermosphere. 4. Earth's atmosphere has six layers: the troposphere, the stratosphere, the mesosphere, the thermosphere, the ionosphere, and the exosphere. 33. #1. (The fuel consumption depends on the drag, which is related to the lift by the lift-to-drag ratio.) Earth's atmosphere is composed of about 78% nitrogen, 21% oxygen, and one percent other gases. Moving upward from ground level, these layers are called the troposphere, stratosphere, mesosphere, thermosphere, and exosphere. Facts About the Stratosphere Tower | USA Today [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. As previously mentioned, the stratosphere is one of the five layers that make up the Earth's atmosphere. Interesting Facts About Mercury. Planes fly in the stratosphere to avoid turbulence and fly longer distances using less fuel. Facts About The Exosphere: The Outermost Layer Of The Atmosphere.
