Composition of air Nitrogen 78 Oxygen 21 Water vapor 0014 Argon lt 1 Carbon dioxide 0037 Disruption of Biogeochemical Cycles Carbon cycle addition of carbon dioxide to the troposphere mostly by burning fossil fuels. Key Terms. Atmosphere. – a thin envelope of gases that encircles the earth and other particles (aerosols). Weather. – the state of the atmosphere at a specific place and time. Meteorology. – the study of the atmosphere and the processes that cause weather. Essential Points. Heat, Temperature and Temperature Scales. The Electromagnetic Spectrum. Composition of the Atmosphere. Layers in the atmosphere are defined by temperature profiles. How pressure varies in the atmosphere. Sunrise . from space over the South China Sea. An astronaut would see something like this; clearly defined bands of color through the atmosphere as the sun rises. High-peaking cumulus clouds, topping out in anvil-head cirrus can be seen as black shadows against the sunlit horizon. The brightness of the colors in the atmosphere in this photograph is due to the amount of dust in the atmosphere. More dust is found in near the equator. There are various sources for such upper level dust. Many dust storms in Africa and ash clouds from major volcanic eruptions are two reasons. . A Reynolds’ Production 2010. Review Really Fast.
