This layer holds 19 percent of the atmosphere's gases but very little water vapor. Thats almost as wide as Earth itself. 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. The bottom of the stratosphere is around 10 km (6.2 miles or about 33,000 feet) above the ground at middle latitudes. This material is based upon work supported by the National Center for Atmospheric Research, a major facility sponsored by the National Science Foundation and managed by the University Corporation for Atmospheric Research. Ozone layer facts and information - Environment Facts About The Mesosphere - What It Is And Its Defining Characteristics [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. 12. The stratosphere is situated just above the troposphere, with a thin layer of air called the tropopause separating the two layers. "Strat" means layer. 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. 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. UCAR/Randy Russell 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. The layer made of layers Above the troposphere and below the mesosphere, we have the stratosphere. This is just an estimate, however, as the lower and upper boundaries actually vary with the latitude of the earth. The ozone layer is situated within this layer. The stratosphere begins at around 10 kilometers above the surface of the earth. What Causes Air Pollution? Temperature decreases with height throughout the mesosphere. This is also where you'll find low Earth orbit satellites. This is how certain gases become trapped in the stratosphere, like CFC's and ozone. Ozone depletion | Facts, Effects, & Solutions | Britannica High School Math Teacher for the 2023-2024 School Year at The Grove However, this feature allows commercial airliners to fly in the lower stratosphere while traveling faster and save fuel. 32. This is due to gravity, but mostly due to the temperature inversion in the tropopause that prevents gases from entering the layer. Because the temperature in the tropopause and lower stratosphere is largely constant with increasing altitude, very little convection and its resultant turbulence occurs there. 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. The mesosphere is the third layer of the atmosphere (above the troposphere and stratosphere.) (The fuel consumption depends on the drag, which is related to the lift by the lift-to-drag ratio.) 4. The stratosphere accounts for approximately 24% of the earth's total atmosphere. The stratosphere is composed primarily of nitrogen and oxygen. Certain birds can fly to this altitude, including cranes, swans, and vultures. The stratosphere is a layer of Earth's atmosphere. One of the most surprising things about the stratosphere is not its characteristics but about what you find in this layer. 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. It is possible to send research balloons into the stratosphere. The stratosphere was discovered in 1900 by French meteorologist Lon Teisserenc de Bort. The coldest temperatures are found in the mesopause. 50 Interesting Facts About The Atmosphere - The Fact File Acid rains form when nitrogen oxide or Sulphur dioxide combines with water vapor in the atmosphere.

As harmful UV rays from the sun become absorbed in the ozone layer, this layer heats up. Ninety-nine percent of the gases that compose the atmosphere are located below a height of 32 km (20 miles). As this article clearly illustrated, the stratosphere has a crucial role to play in maintaining the atmosphere and all life in it. They are much similar to warm breath during cold weather. Atmosphere | NASA Climate Kids The stratosphere also traps certain gasses known as CFC's, which are chemicals derived from aerosol. 5. 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. On November 29, 1973, a Rppell's vulture (Gyps rueppelli) was ingested into a jet engine 11,278m (37,000ft) above the Ivory Coast. Convection is when gasses cool down as they rise, allowing them to condense onto air particles and form clouds. The height of the bottom of the stratosphere varies with latitude and with the seasons. Stratospheric warming of the polar vortex results in its weakening. 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. Facts About The Exosphere: The Outermost Layer Of The Atmosphere. The rising air is literally freeze dried; the stratosphere is a very dry place. 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. 16. This layer of our atmosphere has its own set of layers. Stated another way, it allows the airliner to fly faster while maintaining lift equal to the weight of the plane. Of all the atmospheric layers, this is the most closest to the Earth. It surrounds our planet, keeps us warm, gives us oxygen to breathe, and it is where our weather happens. The burning of fossil fuels discharges carbon dioxide, while agricultural developments deposit a lot of methane and nitrogen oxides into the atmosphere. We take a closer look at the stratosphere and its defining characteristics. Commercial jet aircraft fly in the lower stratosphere to avoid the turbulence which is common in the troposphere below. Certain swans, cranes, and vultures can fly in the lower stratosphere. When greenhouse gases rise into the atmosphere, they form chloride ions that destroy the ozone layer by making holes in it. 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. Never miss out again when another interesting and helpful article is released and stay updated, while also receiving helpful tips & information by simplyclicking on this link .Until next time, keep your eye on the weather! These gases are found in layers (troposphere, stratosphere, mesosphere, thermosphere, and exosphere) defined by unique features such as temperature and pressure. 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 It is the only layer of the atmosphere where temperature inversion occurs. 22. It not only examines what the stratosphere is but also looks at the characteristics or facts that define it. This part of the atmosphere is the most dense. Though the atmosphere may appear uniform to the naked eye, it is actually similar to a layer cake. The shiny blue marble continues to fascinate us since the time we began walking across its surfaces. This is exactly the opposite of the behavior in the troposphere in which we live, where temperatures drop with increasing altitude. A two-step reactive mechanism produces ozone in the stratosphere naturally. The water ice appears younger than we would expect. Ozone (O3) photolysis produces O and O2. It is the reason why the sky appears blue. However, temperature increases with altitude in the stratosphere, which is opposite from the troposphere. These are generated when cold atmospheric air blends with the hot, humid exhaust. Exosphere widely contains particles of helium and hydrogen. This increase of temperature with altitude is characteristic of the stratosphere; its resistance to vertical mixing means that it is stratified. What's in the Atmosphere? 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). Ozone layer lies about 19-32 km over the earths surface. Privacy Policy copyright 2003-2023 Study.com. These elements react with toxic gases, salt, smoke, and volcanic ash. Between the troposphere and stratosphere is the tropopause border that demarcates the beginning of the temperature inversion. Stratosphere | NASA Space Place - NASA Science for Kids The exosphere gradually fades away into the realm of interplanetary space. . Theexosphereis really, really big. This UV radiation is important for the production of vitamin D in humans, but too much can destroy tissue. However, just above that is an equally important layer called the stratosphere. Stratosphere Definition & Meaning - Merriam-Webster This layer of our atmosphere has its own set of layers. Its upper edge has maximum ozone concentration, referred to as the ozone belt. The troposphere, the lowest layer, is right below the stratosphere. It is the only atmospheric layer where temperature inversion occurs and the region where the ozone layer is situated. Most meteors burn up in the mesosphere. In this article, we are going to learn about the atmosphere. 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. 14. Sunlight is reflected in every direction by the gases present in the atmosphere. Ozone layer | Description, Importance, & Facts | Britannica The particles in the exosphere do not behave like gases. Earth's Atmosphere | NASA Space Place - NASA Science for Kids It surrounds the globe and protects it by absorbing the infrared rays from the sun. They result from ionized particles from the sun striking the upper atmosphere above the poles. ], While looking up at the sky on a cloud-free day, one will see what looks like a continuous piece of[], The stratosphere is the second layer of the atmosphere, It extends from a height of approximately 10 km. The stratosphere (/strtsfr, -to-/) is the second layer of the atmosphere of the Earth, located above the troposphere and below the mesosphere.
