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 air in the stratosphere is about 1000 thinner than the air at sea level in the troposphere. It extends from about 50 to 85 km (31 to 53 miles) above our planet. This results in an increase in temperature from about -76 degrees Fahrenheit to around 5 degrees Fahrenheit. Its magnetic field goes up to 60,000 km into space. As a result of the EUs General Data Protection Regulation (GDPR). 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], The mechanism describing the formation of the ozone layer was described by British mathematician Sydney Chapman in 1930. The infamous ozone layer is found within the stratosphere. Stratosphere - The Stratosphere makes up around 25% of the total of Earth's atmosphere, and is home to more than 90% of our Earth's O-Zone layer. Most of the clouds form in the troposphere, just below the stratosphere. Fun Stratosphere Facts for Kids. Mercury has an atmosphere that changes with its distance to the Sun. As a result, the air in the stratosphere is about 1000 times thinner in the stratosphere than at sea level in the troposphere. Ozone protects life on Earth from the Sun's ultraviolet (UV) radiation. Write CSS OR LESS and hit save. Above the stratosphere is the mesosphere. We are not permitting internet traffic to Byjus website from countries within European Union at this time. This UV radiation is important for the production of vitamin D in humans, but too much can destroy tissue. It starts to glow, and the rocks begin to fly off. Although the sun and other planets have magnetospheres, the earths magnetosphere is the strongest one of all the rocky planets. The next higher layer above the stratosphere is the mesosphere. 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. The stratosphere is actually crucial to allowing us to live on earth, because within the stratosphere you will find the ozone layer. Autumn Skies Online Pty Ltd is compensated for referring traffic and business to these companies., The Earth's atmosphere consists of five layers. 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. It surrounds the globe and protects it by absorbing the infrared rays from the sun. The stratosphere is the second layer of the atmosphere, which is composed of a total of five layers. It is the only atmospheric layer where temperature inversion takes place. These distances vary slightly due to elevation changes on the Earth. As mentioned in the introduction, certain birds such as cranes, swans, and vultures can fly at this altitude. The stratosphere is a layer of Earth's atmosphere. It is the reason why the sky appears blue. Strat means layer. 31. 28. The oxygen atom product combines with atmospheric molecular oxygen to reform O3, releasing heat. 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. Luckily the situation has improved since the ban of chlorofluorocarbon. The stratosphere is very cold, ranging in temperatures from negative 68F to negative 5F. This layer of our atmosphere has its own set of layers. We take a closer look at the stratosphere and its defining characteristics. The coldest temperatures are found in the mesopause. All other trademarks and copyrights are the property of their respective owners. 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). Scientists have been warning people for many years about the damage we are doing to the ozone layer. It is the second layer of the atmosphere as you go upward. 110 lessons. As previously mentioned, the stratosphere is one of the five layers that make up the Earth's atmosphere. One wild characteristic of the stratosphere is a phenomenon that occurs, which is known as blue jets. The atmosphere comprises five layers: troposphere, stratosphere, mesosphere, thermosphere and exosphere. There are forms of biological bacteria living in the stratosphere. What's in the Atmosphere? The stratosphere is the second layer of the atmosphere. The presence of moisture in the atmosphere is 19. Without it, the earths surface would be so cold that living here would not be possible. measured by the humidity of the air. Above the troposphere and below the mesosphere, we have the stratosphere. Between the troposphere and stratosphere is the tropopause border that demarcates the beginning of the temperature inversion. The atmosphere comprises five layers: troposphere, stratosphere, mesosphere, thermosphere and exosphere. In the stratosphere - 'strato' means layer and sphere is the shape of the earth. Another large-scale feature that significantly influences stratospheric circulation is the breaking planetary waves[15] resulting in intense quasi-horizontal mixing in the midlatitudes. Any opinions, findings and conclusions or recommendations expressed in this material do not necessarily reflect the views of the National Science Foundation. Different definitions place the top of the exosphere somewhere between 100,000 km (62,000 miles) and 190,000 km (120,000 miles) above the surface of Earth. Acidic rains destroy plants and animals, and if it reaches rivers and lakes, it destroys all the aquatic life. Ozone is a blue pungent-smelling gas that helps to absorb the ultraviolet radiation in the sun rays. Some of these waves and tides carry energy from the troposphere upward into the stratosphere, others convey energy from the stratosphere up into the mesosphere. In fact, the ozone layer absorbs most of the UV radiation the sun sends to us. This diagram shows some of the features of the stratosphere. Earths atmosphere has six different layers. The rapid photolysis and reformation of ozone heat the stratosphere, resulting in a temperature inversion. Heat is produced in the process of the formation of Ozone, and this heat is responsible for . A good percentage of the earths population breathes contaminated air, primarily sulfur dioxide and carbon monoxide emitted by industrial factories. It surrounds our planet, keeps us warm, gives us oxygen to breathe, and it is where our weather happens. What Is the Greenhouse Effect? Ozone layer lies about 19-32 km over the earths surface. Earth is a great planet to live on because it has a wonderful atmosphere around it. This allows the stratosphere to have an increasing temperature with altitude. Thats the opposite of how the layers work in the troposphere, where we live. It changes sometimes unpredictably Earth's atmosphere has six layers: the troposphere, the stratosphere, the mesosphere, the thermosphere, the ionosphere, and the exosphere. Earth's atmosphere has a series of layers, each with its own specific traits. Solar ultraviolet radiation (sunlight) separates an oxygen molecule into two different oxygen atoms in the first step. This is just an estimate, however, as the lower and upper boundaries actually vary with the latitude of the earth. Interesting Facts About Mercury. It sets it apart from the other atmospheric layers by temperature rising instead of dropping as altitude increases, a process called temperature inversion. 6. Enrolling in a course lets you earn progress by passing quizzes and exams. Ionosphere plays a vital role in radio signals broadcast on the earths surface. 32. 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. Here are 50 Interesting facts about the atmosphere that you probably didnt know. The jet stream flows near the border between the troposphere and the stratosphere. Blue jets are an extremely rare form of lightning or electrical discharge from clouds in the troposphere. As a result, it tends to trap any and all gases that enter this region of the atmosphere. Three Highest Thrill Rides in the World. As you rise through the troposphere, the temperature decreases to around -60 degrees Fahrenheit. The exosphere is really, really big. This list does not contain all the data available about the stratosphere but highlights the key facts and characteristics of this layer. 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). These events often precede unusual winter weather [16] and may even be responsible for the cold European winters of the 1960s.[17]. Brewer-Dobson Circulation occurs in the stratosphere. Ozone is important for ensuring that just the right amount of ultraviolet radiation reaches the earth. The stratosphere is the second layer of the atmosphere, in between the troposphere and the mesosphere. The stratosphere (/strtsfr, -to-/) is the second layer of the atmosphere of the Earth, located above the troposphere and below the mesosphere. Despite Mercury's weak magnetic field, it behaves similarly to Earth's. Ice clouds form in this layer which is visible when lighted from beneath during sunset. The word 'stratosphere' is derived from the word 'strato' meaning layer, and 'sphere' which is earth's shape. The stratosphere is where youll find the very important ozone layer. #1. The temperatures in the ozone belt are higher than in the troposphere since the ozone absorbs the ultraviolet rays.

Clouds form due to convection, which is uncommon in the stratosphere. . Meteorological phenomena are limited to the troposphere since they result from the earths rotation and suns radiation on the atmosphere. Because the temperature in the tropopause and lower stratosphere is largely constant with increasing altitude, very little convection and its resultant turbulence occurs there. Stratosphere. 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. Temperature decreases with height throughout the mesosphere. 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 caused due to a highly non-linear interaction between the vertically propagating planetary waves and the isolated high potential vorticity region known as the polar vortex. 14. In 1985, they observed a hole in the ozone layer above the Antarctic. The top of the stratosphere is called the stratopause, above which the temperature decreases with height. Endeavoring to achieve professional growth through ongoing development of skills and using new and accepted methods of . Due to the high speed of the meteor, it generates a lot of heat resulting from high friction between the particles and the meteor. Unlike the troposphere however it is colder closer to the earth and warmer as it gets closer to the mesosphere. Temperature increases with height until the estimated top of the thermosphere at 500 km. 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. In this region, the temperature increases with height. There are a few other atmospheric layers as well -- you can take a look at a diagram of these below.
