While common in the troposphere, very little convection takes place in the stratosphere. It not only examines what the stratosphere is but also looks at the characteristics or facts that define it. It also consists of a layer known as the ozone layer, a blanket of ozone that absorbs harmful ultraviolet (UV) rays from the sun. 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. The oxygen atom product combines with atmospheric molecular oxygen to reform O3, releasing heat. These "blue jets" appear above thunderstorms, and extend from the bottom of the stratosphere up to altitudes of 40 or 50 km (25 to 31 miles). Each year, this large amount of water is recycled about 40 times. But its not the same everywhere. Earth's atmosphere is similar to a jacket for our planet. The stratosphere is located above the troposphere and below the mesosphere. 2 It extends from a height of approximately 65 km (40 miles) to 85 km (53 miles) above the Earth's surface. The Earth's atmosphere is very important, as each layer plays a role for life on Earth. This includes its location, what it is composed of, the temperature range, and its density.
77 Exciting Facts about the Atmosphere - LovePsychologys PSCs are also called nacreous clouds. Layers of the atmosphere: troposphere, stratosphere, mesosphere . Polar stratospheric clouds (PSCs) are the exception. It is in the thermosphere that the space shuttle flew. This breaking is much more pronounced in the winter hemisphere where this region is called the surf zone. The stratosphere ( / strtsfr, - to -/) is the second layer of the atmosphere of the Earth, located above the troposphere and below the mesosphere. As altitude increases, air density in the layers of the atmosphere decrease. Most meteors burn up in the mesosphere. A good percentage of the earths population breathes contaminated air, primarily sulfur dioxide and carbon monoxide emitted by industrial factories. copyright 2003-2023 Study.com. He concluded that there was another layer in the atmosphere above the troposphere, which he called the stratosphere. There are some species of birds capable of flying in the stratosphere. As you go up, it becomes colder. [5] Stratospheric temperatures also vary within the stratosphere as the seasons change, reaching particularly low temperatures in the polar night (winter). It contains 80% of the atmospheric weight, making it the densest layer. 90% of the ozone layer is found in the stratosphere's upper crust. The presence of moisture in the atmosphere is For years, CFCs - a chemical used in aerosols - were transported the stratosphere via convection and became trapped there. Clouds rarely form in the stratosphere for this reason as well, as the air is very dry. The stratosphere is the second layer of the Earth's atmosphere, laying just above the troposphere and below the mesosphere. It has increased the number of respiratory conditions such as asthma. All air entering the stratosphere must pass through the tropopause, the temperature minimum that divides the troposphere and stratosphere. It is the reason why the sky appears blue. It borders the troposphere below through a thin transitional space called the tropopause. Folland. The ozone layer is very important, as it protects life on Earth from the majority of the UV rays emitted from the sun. The exosphere is really, really big. It is the highest layer.
We now know that there are additional ozone loss mechanisms and that these mechanisms are catalytic meaning that a small amount of the catalyst can destroy a great number of ozone molecules. 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. Solar ultraviolet radiation (sunlight) separates an oxygen molecule into two different oxygen atoms in the first step. While the stratosphere is dry, additional water vapor is produced in situ by the photochemical oxidation of methane (CH4). Ozone protects life on Earth from the Sun's ultraviolet (UV) radiation. 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. Polar Stratospheric Clouds develop in this layer near the poles at an altitude of 15 - 25 kilometers. Any opinions, findings and conclusions or recommendations expressed in this material do not necessarily reflect the views of the National Science Foundation. Some researchers and even students have sent helium balloons with cameras to record the stratosphere. Earths atmosphere has six different layers. The holes in the ozone layer have been recorded above the Antarctica seasonally, as well as in other parts of the world.

The stratosphere contains the ozone layer, which shields the Earth from harmful radiation emitted from the Sun. The water ice appears younger than we would expect. As previously mentioned, the stratosphere is one of the five layers that make up the Earth's atmosphere. In this article, we are going to learn about the atmosphere. The word 'stratosphere' is derived from the word 'strato' meaning layer, and 'sphere' which is earth's shape. The thermosphere extends from about 90 km to 500 kmand 1,000 km above our planet. The wind, which is the air current, is generated when the hot air rises and gets replaced by colder air. It changes sometimes unpredictably The coldest temperatures in Earths atmosphere, about -90 C (-130 F), are found near the top of this layer. [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. 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. [6] Winds in the stratosphere can far exceed those in the troposphere, reaching near 60m/s (220km/h; 130mph) in the Southern polar vortex. This is just an estimate, however, as the lower and upper boundaries actually vary with the latitude of the earth. The particles in this layer are electrically charged, and when they hit each other, aurora australis can be observed. This part of the atmosphere is the most dense. Planting trees is one of the efforts that people have done to try to minimize damage and to help rebuild the damaged ozone layer. The image above illustrates the layers of Earth's atmosphere and their approximate distances from the Earth's surface. Thus it means layer which surrounds the earth.
Exosphere | NASA Space Place - NASA Science for Kids 77 Amazing, Interesting, and Exciting Facts about the Atmosphere The stratosphere is actually crucial to allowing us to live on earth, because within the stratosphere you will find the ozone layer. 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. But there are no mountains high enough to reach the stratosphere, so you dont have to worry about that. [18] When the vortex is strong, it keeps the cold, high-pressure air masses contained in the Arctic; when the vortex weakens, air masses move equatorward, and results in rapid changes of weather in the mid latitudes. This layer of our atmosphere has its own set of layers. The ozone layer lies in the stratosphere, which absorb the majority of harmful UV radiation from the sun. 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. Stated another way, it allows the airliner to fly faster while maintaining lift equal to the weight of the plane. 20. 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. Without it, the earths surface would be so cold that living here would not be possible. It keeps us warm, it gives us oxygen to breathe, and its where our weather happens. 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. The aurora, the Northern Lights and Southern Lights, occur in the thermosphere. The burning of fossil fuels discharges carbon dioxide, while agricultural developments deposit a lot of methane and nitrogen oxides into the atmosphere. The ozone layer absorbs the majority of these rays, shielding life from harmful radiation. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. These elements react with toxic gases, salt, smoke, and volcanic ash. Most airplanes or jets travel in the lower part of the stratosphere. Most turbulence at this altitude is caused by variations in the jet stream and other local wind shears, although areas of significant convective activity (thunderstorms) in the troposphere below may produce turbulence as a result of convective overshoot. This is also where you'll find low Earth orbit satellites. The stratosphere is one of five layers of the earth's atmosphere. The atmosphere consists of five distinct layers, with the stratosphere being the second, situated just above the troposphere. Since the ozone layer absorbs UV rays from the sun, it heats up, which allows temperatures to increase as altitude increases. So, what does the stratosphere do? In comparison, the warmest in the thermosphere. The stratosphere also contains the ozone layer, which absorbs harmful ultraviolet radiation as it enters our atmosphere from the sun. 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. One wild characteristic of the stratosphere is a phenomenon that occurs, which is known as blue jets. The following list highlights the characteristics and facts of the stratosphere in more detail. There is very little water vapor in this layer of the atmosphere, so clouds are a rare occurrence. These distances vary slightly due to elevation changes on the Earth. The stratosphere is one of the 5 layers of the atmosphere, situated above the troposphere and below the mesosphere at an altitude of 10 km (6 miles), extending to 50 km (30 miles). Planes and jets will sometimes choose to fly in the stratosphere, where there are no clouds or weather that can affect the ride. 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. 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. (The fuel consumption depends on the drag, which is related to the lift by the lift-to-drag ratio.) #1. Life as we know it wouldnt be possible without this layer of protection. It is important because it contains the ozone layer, which protects the Earth from harmful UV rays. The stratosphere is the second layer of the atmosphere. . Stratosphere is the second layer. The lower portion of the stratosphere is nearly isothermal (a layer of constant temperature), whereas temperatures in its upper levels increase with altitude. Stratosphere. Certain birds will even fly in the stratosphere, including swans, cranes, and vultures! No tracking or performance measurement cookies were served with this page. When greenhouse gases rise into the atmosphere, they form chloride ions that destroy the ozone layer by making holes in it. Convection is when gasses cool down as they rise, allowing them to condense onto air particles and form clouds. They shoot upwards through the stratosphere in a blue column to altitudes as high as 50km! This is the opposite of what happens in the troposphere, the layer of the atmosphere closest to Earth. 5. It's about 6,200 miles (10,000 kilometers) thick. Starting at ground level, it extends upward to about 10 km (6.2 miles or about 33,000 feet) above sea level. This site is owned and operated by Autumn Skies Online Pty Ltd, a limited liability company headquartered in Somerset West, South Africa. A single chlorine atom can destroy more than a hundred thousand ozone molecules.
The Mesosphere | Center for Science Education Air density in this layer gradually decreases as you go higher.

The stratospheric air is extremely thin and dry since the vast majority of atmospheric gases (and weather activity) are limited to the troposphere. The stratosphere is a layer of Earths atmosphere. Current map of global winds and temperatures at the 10 hPa level. These events often precede unusual winter weather [16] and may even be responsible for the cold European winters of the 1960s.[17]. This list does not contain all the data available about the stratosphere but highlights the key facts and characteristics of this layer. It has different layers with different qualities. 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. At the top of the stratosphere, the density of the air is close to zero. The Concorde aircraft cruised at Mach 2 at about 60,000ft (18km), and the SR-71 cruised at Mach 3 at 85,000ft (26km), all within the stratosphere. We are not permitting internet traffic to Byjus website from countries within European Union at this time. 11.
What are 3 interesting facts about Mercury? The Earth's atmosphere is a mixture of several gases. Above the troposphere and below the mesosphere, we have the stratosphere. If you look up at the sky, either on a clear day or a starry night, it probably wouldn't occur to you that you are looking through layers. Write CSS OR LESS and hit save. Ozone is a gas made up of three oxygen atoms (O 3). The stratosphere is the second layer of the Earth's atmosphere, and lies approximately 10km to 50km above the Earth's surface. Learn about the stratosphere, including the stratosphere's definition and importance. This layer of Earth's atmosphere is about 319 miles (513 kilometers) thick.
Nasa Ozone Watch: Ozone facts [4] The temperature inversion is in contrast to the troposphere, near the Earth's surface, where temperature decreases with altitude. The infamous ozone layer is found within the stratosphere. Terms & Conditions The stratosphere is one of five layers of the atmosphere. 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. "Strat" means layer. However, it is made up out of five different layers: The troposphere, stratosphere, mesosphere, thermosphere, and exosphere. 33. 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. "Strat" means layer. Create your account. This article focus on the stratosphere, Earth's second layer. One of the most surprising things about the stratosphere is not its characteristics but about what you find in this layer. 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. 25. The ionosphere stretches roughly 50 to 400 miles above Earth's surface, right at the edge of space. This layer of our atmosphere has its own set of layers. As the ozone layer absorbs UV radiation, it causes the temperature in this layer to increase. The stratosphere is the second layer in the Earth's atmosphere. This increase of temperature with altitude is characteristic of the stratosphere; its resistance to vertical mixing means that it is stratified. At an altitude of 100 km above sea level, a border represents the separation between the atmosphere and outer space. The stratosphere also traps certain gasses known as CFC's, which are chemicals derived from aerosol. Although some experts consider the thermosphere to be the uppermost layer of our atmosphere, others consider the exosphere to be the actual "final frontier" of Earth's gaseous envelope. 15. 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. The QBO induces a secondary circulation that is important for the global stratospheric transport of tracers, such as ozone[14] or water vapor. It contains the ozone layer and is between the troposphere, the first layer of the atmosphere, and the mesosphere, the third layer of the atmosphere. Discover fun facts about the stratosphere and stratosphere characteristics. At the outer limit of the magnetic field is the magnetosphere. Without the stratosphere, life on Earth would be very different or non-existent, as the shielding of the sun's radiation is important for known Earth life.
