The amount of oxygen in the atmosphere has fluctuated over the last 600 million years, reaching a peak of about 30% around 280 million years ago, significantly higher than today's 21%. Field study 3). The troposphere is the lowermost layer of the atmosphere. He gathered breathed air (hence rich in CO2) and closed it hermetically in two containers, an empty one, and another one containing a plant. Two particularly important examples of this were the explanation of how the ozonosphere forms and maintains itself by Sydney Chapman and Gordon Dobson and the explanation on smog by Haagen-Smit. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Total atmospheric mass is 5.1480×1018 kg (1.135×1019 lb),[35] about 2.5% less than would be inferred from the average sea level pressure and Earth's area of 51007.2 megahectares, this portion being displaced by Earth's mountainous terrain. https://en.wikipedia.org/w/index.php?title=Atmosphere_of_Earth&oldid=1000094566, Wikipedia indefinitely semi-protected pages, Short description is different from Wikidata, Wikipedia articles needing clarification from February 2016, Articles needing additional references from October 2013, All articles needing additional references, Creative Commons Attribution-ShareAlike License, Exosphere: 700 to 10,000 km (440 to 6,200 miles), Thermosphere: 80 to 700 km (50 to 440 miles), Stratosphere: 12 to 50 km (7 to 31 miles). Atmospheric circulation is the large-scale movement of air through the troposphere, and the means (with ocean circulation) by which heat is distributed around Earth. [43] How Earth at that time maintained a climate warm enough for liquid water and life, if the early Sun put out 30% lower solar radiance than today, is a puzzle known as the "faint young Sun paradox". The practical role of geodesy is to provide a network of accurately surveyed points on the Earth’s surface, the vertical elevations and geographic positions of which are precisely known and, in turn, may be incorporated in maps. The study of earth s atmosphere is called. News, analysis, experiments, videos, games, and educational paths on the issues of energy and the environment for complete and topical information. He discovered, moreover, that hydrogen combines with oxygen to produce a dew that looked like water. Nitrogen and oxygen account for 99 percent of the gases in dry air, with argon, carbon dioxide, helium, neon, and other gases making up minute portions. It lies above the troposphere and is separated from it by the tropopause. The French chemist Antoine Lavoisier (1743-1794), father of modern chemistry, carried out important researches to understand the nature of combustion. It was Lavoisier who recognized that air is a combination of an active gas, oxygen, that feeds combustion and breathing, and an inactive gas, nitrogen. The constant re-arrangement of continents by plate tectonics influences the long-term evolution of the atmosphere by transferring carbon dioxide to and from large continental carbonate stores. [50], On October 19, 2015, NASA started a website containing daily images of the full sunlit side of Earth on http://epic.gsfc.nasa.gov/. It was Lavoisier who recognized that air is a combination of an active gas, oxygen, that feeds combustion and breathing, and an inactive gas, nitrogen. The atmosphere becomes thinner and thinner with increasing altitude, with no definite boundary between the atmosphere and outer space. Thus air pressure varies with location and weather. Nebular theory. Meteorologyincludes the study of weather patterns, clouds, hurricanes, and tornadoes. Fifty percent of the total mass of the atmosphere is located in the lower 5.6 km (3.5 mi; 18,000 ft) of the troposphere. More sophisticated models are used to predict orbital decay of satellites. Study Of Earth S Atmosphere Is Called. By volume, dry air contains 78.09% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. (C) The concentration of CO2 has been increasing in recent decades In general, air pressure and density decrease with altitude in the atmosphere.
