Composition of the atmosphere
The earth's atmosphere contains mostly nitrogen and oxygen about 78 percent is nitrogen, and about 21 percent is oxygen it also contains small quantities of other gases, some of which are carbon dioxide, water vapor, ozone, helium and hydrogen. Structure the atmosphere is divided into layers according to major changes in temperature gravity pushes the layers of air down on the earth's surface. This is mr buss earth science farmington high school screencast 81 composition of the atmosphere. Scientists are afraid that the buring of fossil fuels such as coal and oil are adding more carbon dioxide to the atmosphere e water vapor - 00 to 40% - essential for life processes also prevents heat loss from the earth. The surfaced-based homosphere includes the troposphere, stratosphere, mesosphere, and the lowest part of the thermosphere, where the chemical composition of the atmosphere does not depend on .

In researching a post about the kármán line i discovered the nasa msie e-90 atmosphere model (thanks to rhett allain) which models the composition of earth's atmosphere up to an elevation of 1000km. Composition of earth's atmosphere the early greeks considered air to be one of four elementary substances along with earth, fire, and water, air was viewed as a fundamental component of the universe.
Atmosphere, composition and structure photo by: nejron photo earth's atmosphere is composed of about 78 percent nitrogen, 21 percent oxygen, and a 1-percent mixture of minor gases dominated by argon. The composition of the present atmosphere however required the formation of oxygen to sufficient levels to sustain life, and required life to create the sufficient levels of oxygen this era of evolution of the atmosphere is called the biological era. The mesosphere is a layer of earth's atmosphere it starts about 50 km (31 miles) above the ground and goes all the way up to 85 km (53 miles) high the layer below it is called the stratosphere . Most of the atmosphere is composed of nitrogen in addition to 78 percent nitrogen, 21 percent is oxygen the remaining 1 percent is composed of argon, carbon dioxide, and other gases 99 percent of the atmosphere is found within 32 km of the surface of the earth. Atmosphere, composition and structure composition of the atmosphere atmospheric structure the past and future of the atmosphere resources source for information on atmosphere, composition and structure: the gale encyclopedia of science dictionary.
Understanding atmospheric composition is both simple and handy in understanding how mankind can influence climate many people think the atmosphere is just too big for humans to influence. The mesosphere is a layer of earth's atmosphere the mesosphere is directly above the stratosphere and below the thermosphereit extends from about 50 to 85 km (31 to 53 miles) above our planet. Atmosphere at os here (ăt′mə-sfîr′) n 1 the gaseous mass or envelope surrounding a celestial body, especially the one surrounding the earth, and retained by the . In any given volume of air, nitrogen accounts for 78 percent of the gases that comprise the atmosphere, while oxygen makes up 21 percent argon, carbon dioxide, and traces of other gases make up the remaining one percent. Earth is the only planet in the solar system with an atmosphere that can sustain life the blanket of gases not only contains the air that we breathe but also protects us from the blasts of heat .
Composition of the atmosphere
What's in the air the air in our atmosphere is composed of molecules of different gases the most common gases are nitrogen (78%), oxygen (about 21%), and argon (almost 1%). The composition of the atmosphere encodes a great deal of information bearing on its origin furthermore, the nature and variations of the minor components reveal extensive interactions between the atmosphere, terrestrial environment , and biota. The chemical composition of air varies across the different layers of earth's atmosphere the oceans and the biosphere exchange vast quantities of gases with the atmosphere's lowest layer the carbon and nitrogen cycles play key roles in these processes.
Breathe in and you can appreciate that the earth’s atmosphere has everything needed to support life on earth but what’s in it let’s take a look at the composition of the earth’s . Composition of the atmosphere earth’s lower atmosphere is a mixture of many gases called air the two main gases in air are nitrogen and oxygen together, they . The total mass of the atmosphere is approximately 53 0 18 kg, against the 14 0 21 kg mass of the hydrosphere (oceans, sees, lakes, rivers, groundwater, snow and ice) and 598 0 24 kg mass of the earth.

Atmosphere [gr,=sphere of air], the mixture of gases surrounding a celestial body with sufficient gravity to maintain it although some details about the atmospheres of other planets and satellites are known, only the earth's atmosphere has been well studied, the science of which is called meteorology meteorology,. The composition of planetary atmospheres 1 problem 1 – draw a pie graph (circle graph) that shows the atmosphere constituents for mars and earth. The most common atmospheric gas, nitrogen (chemical symbol n 2) accounts for about 78% of the atmosphere nitrogen gas is largely inert, meaning that it does not readily react with other substances to form new chemical compounds the next most common gas, oxygen (o 2), makes up about 21% of the .
