Though its gaseous composition is similar, but the gaseous mass is only 15% of the total atmosphere, and it contains more ozone. Diagram of the layers within Earth's atmosphere. As all gases are dissolved in natural waters, the hydrosphere maintains equilibrium with the atmosphere. It consists of less gaseous mass, no water vapour, and ozone is also present in it. It is the first or lowest layer of atmosphere. Water vapour can condense into clouds and fog and also as snow and hail. 2. Share Your PPT File. What is the significance of transpiration? How Many Number of Layers in Atmosphere. Your email address will not be published. The thermosphere is where satellites and space stations, like the International Space Station, orbit the Earth. The mesosphere extends from just above the stratosphere to 53 miles (85 km) high. Above the troposphere is the tropopause, above the stratosphere is the stratopause, above the mesosphere is the mesopause, and above the thermosphere is the thermopause. Lying between the upper mesosphere and the lower thermosphere is the so-called ionosphere because free electrons and ions exist in this region. Content Guidelines 2. Stratosphere. Illustration of comet, meteor, clouds - 103161243 Here we have mentioned Earth’s 5 layers of the atmosphere in order with the proper diagram. Except the inert Gases, all these components of air serve as metabolites and each circulates through a cycle in which the organisms play an important role. The exosphere is the least dense layer of the atmosphere, comprised of mostly helium and hydrogen. Our atmosphere consists of different five layers. Required fields are marked *. The atmosphere of the earth is the layer of gases (commonly called air) that surrounds the earth and creates an inhabitable environment, maintains temperature, causes weather, and protects its inhabitants from solar radiation. Temperature: Ranges from 32°F (0°C) to -130°F (-90°C), the lowest temperature found on Earth. It is the densest layer, containing more than half the volume of total air. 1. Types of Blood Cells With Their Structure, and Functions, The Main Parts of a Plant With Their Functions, Parts of a Flower With Their Structure and Functions, Parts of a Leaf With Their Structure and Functions, Earth’s Atmosphere: Composition, Climate & Weather –. From lowest to highest, the major layers are the troposphere, stratosphere, mesosphere, thermosphere and exosphere. Here, the constituents remain in neutral state. Answer Now and help others. In this part of the atmosphere the temperature gets colder as the distance above the earth increases, by about 6.5°C per kilometre. The troposphere starts at the Earth's surface and extends 8 to 14.5 kilometers high (5 to 9 miles). Article was last reviewed on Thursday, November 26, 2020, Your email address will not be published. It is called as Troposphere. Its size varies with daytime and nighttime. 14. Review Quiz 1. It lies above the troposphere and extends an average height of about 12 to 50 km above the earth. Atmosphere Zones: 5 Main Zones of Atmosphere | Environment, Atmospheric Temperature and Composition | Atmosphere. The thermosphere extends from the mesopause to about 372 miles (600 km) high. The actual change of temperature with height varies from day to day, depending on the weather.The troposphere contains about 75% of all of the air in the atmosphere, and almost all of the … Not much is known about this layer except that meteoroids burn up here, which prevents them from reaching the Earth’s surface. Moving upward from ground level, these layers are named the troposphere, stratosphere, mesosphere, thermosphere and exosphere. a. Troposphere b. It is important for radio communications and is responsible for auroras. On the basis of information provided by radars, balloons, rockets, satellites at present large number of scientists agree on a point that the height of atmosphere is 29000 kilometer and layer upto 800 kilometer is considered as important part of atmosphere. This is the part of the atmosphere where we live and is closest to the surface of the Earth. In troposphere, the average rate of temperature decrease is 6.4°C per km of ascent, but in Stratosphere the temperature shows a gradual increase. The Different Layers of The Atmosphere The atmosphere can be divided into layers based on its temperature, as shown in the figure below. The Stratosphere layer is very dry as it contains little water vapour. Download a Free Preview or High Quality Adobe Illustrator Ai, EPS, PDF and High Resolution JPEG versions. It differs from the troposphere in that it contains very little water vapours and no clouds.
