PPT-Atmosphere

Composition The atmosphere is made of a variety of gases roughly in the following proportions 78 Nitrogen 20 Oxygen 1 Argon lt1 Carbon Dioxide lt1 Water vapor Air temperature This is the average speed or kinetic energy of all the particles in a mass of air. 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.
