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. . Logan Dougherty. Quick Overview.

Energy is transferred to absorber; absorber emits energy. How does the atmosphere support life?. The atmosphere allows us to breathe. Many different types of organisms need oxygen to perform life processes. Plants require carbon dioxide to undergo photosynthesis. . Sun is the main source of energy for Earth. Radiation of solar ray is main source of energy for Atmosphere. . Diameter of sun – 1382400 kms (109 times more than earth) . Velocity of electro magnetic short waves – 297600 km/ second. In fact, the atmosphere receives very low amount of heat energy from the sun as it receives most of its energy from the long wave terrestrial radiation..
