Document Summary
Quiz for chapter 4: atmosphere and surface energy balances. The passage of shortwave and longwave radiation through the atmosphere is called refraction. Surfaces with high albedo reflect more light than those with low albedo. Energy is transferred from low latitudes to high latitudes by advection. Emissions of sulfer dioxide may offset some of the effects of greenhouse warming by increasing albedo. Naturally occurring carbon dioxide in the atmosphere is responsible for the greenhouse effect. Urban heat islands result from the fact that metal, glass, concrete, and other construction materials reflect more insolation than do natural vegetation and soil. Most longwave energy emitted by earth"s surface is absorbed by the atmosphere before it reaches space. When solar energy entering the earth-atmosphere system is accounted for, 31% is absorbed at earth"s surface; 21% is absorbed by atmospheric gases, dust, and clouds; 3% is absorbed by ozone; and the remaining 45% is reflected back to space.
