Its current composition is the product of billions of years of biochemical modification of the paleographers by living organisms. The term stellar atmosphere describes the outer region of a star, and typically includes the portion starting from the opaque photosphere outwards. Stars with sufficiently low temperatures may form compound molecules in their outer atmosphere. 2. The atmosphere is divided into five layers. * It is thickest near the surface anything out with height until It eventually merges with space. The layers frostiest to highest : – The Troposphere (up to 10 km) It’s the atmosphere adjournments us.
On top of that comes… – The Stratosphere; (10-50 km) Veritable oxygen or water vapor. Aircraft fly In the lower stratosphere. This Sisal’s where the ozone layer exists. On top of that comes.. – The Mesosphere;(50-80 km) This is where most meteors burn up, because the density is highlighter the outer layers. On top of that comes.. – The Troposphere; (80-650 km)practically a vacuum. Includes the Ionosphere (auroras) as well as space stationeries. On top of that comes… – The Exosphere (500-2000 km ) The farthest info Earth’s atmosphere exists. Eased on charged particles and not serially camouflages, some atmospheric models combine the Exosphere Into the Troposphere,making the outermost layer the Magnetosphere, a vast region where atmospherics interact with the solar wind in space. * Names of 1 1 defined layers, some of which commingle with the basic 5. The names of these levels are Troposphere,Troupes (upper boundary), Ozone Layer, Stratosphere, Stratosphere (paperbound), Mesosphere, Masseuse (upper boundary), Troposphere (nondisclosure), Thermostats (upper boundary), Sybase (lower boundary), Exosphere. 3.
Layers of the Atmosphere: The earth is surrounded by the atmosphere, which is the body of air or gases that protects the planet and enables life. Most of our atmosphere is located close to the earth’s surface where It is most dense. The alarm of our planet Is 79% nitrogen and Just under 21% oxygen; the small amount remaining is composed of carbon dioxide and other gases. There are five distinct layers of the earth. Let’s look at each, from closest to farthest from the earth… Troposphere: The layer of the atmosphere closest to the earth is the troposphere. This layer is where weather occurs.
It begins at the surface of the earth and extends out to about m sees I née temperature AT ten troposphere decreases Walt n melting I Nils layer Is known as the lower atmosphere. Stratosphere: Above the troposphere is the stratosphere, which extends to about 30-35 miles above the earth’s surface. Temperature rises within the stratosphere but still remains well below freezing. Mesosphere: From about 35 to 50 miles above the surface of the earth lies the mesosphere, where the air is especially thin and molecules are great distances apart. Temperatures in the mesosphere reach a low of -OFF (-ICC).
The stratosphere and the mesosphere are the middle atmosphere. Troposphere: The troposphere rises several hundred miles above the earth’s surface, from 50 miles up to about 400 miles. Temperature increases with height and can rise to as high as 3,OFF (20000C). Nonetheless, the air would feel cold because the hot molecules are so far apart. This layer is known as the upper atmosphere. Exosphere: Extending from the top of the troposphere to 6200 miles (10,000 km) above the earth is the exosphere. This layer has very few atmospheric molecules, which can escape into space. . Layers Elevation Temperature Composition 1) The troposphere is the first layer above the surface and contains half of the Earth’s atmosphere. Weather occurs in this layer. 2) Many Jet aircrafts fly in the stratosphere because it is very stable. Also, the ozone layer absorbs harmful rays from the Sun. 3) Meteors or rock fragments burn up in the mesosphere. 4) The troposphere is a layer with auroras. It is also where the space shuttle orbits. 5) The atmosphere merges into space in the extremely ethnographers. This is the upper limit of our atmosphere.
