Free and 101 Diagramss of atmosphere structures are available in high definition! When you are learning about the outer part of the sky, you’ll need atmosphere diagrams to help you with the illustration. The atmosphere is made up of several gasses, but is 78.09% Nitrogen, 20.95% Oxygen, between 0.2 and 4% water vapour, plus tiny amounts of Carbon Dioxide, Ozone, Methane, argon, Helium and sulphur dioxide amongst others. The Earth’s atmosphere contains several different layers that can be defined according to air temperature or chemical composition. The diagram below displays some of these layers in an average atmosphere. The atmosphere can be split into distinguishable layers, called the Troposphere, the Stratosphere, the Mesosphere and finally closest to space the Thermosphere.
The troposphere is the lowest layer of the atmosphere. This is the layer where we live and where weather happens. Temperature in this layer generally decreases with height. The boundary between the stratosphere and the troposphere is called the tropopause. Above the tropopause lies the stratosphere. In this layer the temperature increases with height. This is because the stratosphere houses the ozone layer. The ozone layer is warm because it absorbs ultraviolet (UV) rays from the sun. You can see the details on the following atmosphere diagrams.
The mesosphere is the layer above the stratosphere. The temperature decreases with height here just like it does in the troposphere. The thermosphere is the uppermost layer of the atmosphere. In this layer the temperature increases with height because it is being directly heated by the sun. This layer contains two parts: (1) Ionosphere – This is the lower part of the thermosphere. It extends from about 80 to 550 km. Gas particles absorb ultraviolet and X-ray radiation from the sun. The particles of gas become electrically charged (ions). Radio waves are bounced off the ions and reflect waves back to earth. This generally helps radio communication. (2) Exosphere – the upper part of the thermosphere. It extends from about 550 km for thousands of kilometers. Air is very thin here. This is the area where satellites orbit the earth.
Using the illustrations as provided in the diagrams above, it will be easier for you to learn the structure of the atmosphere. All pictures are free to be saved and you can also find the other educational diagrams in the other posts on this site!
