Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group. . . . a Pie Chart. Pie charts are best to use when you are trying to compare parts of a whole.
About 51% of solar energy reaching the earth is absorbed by the Earth's surface. Incoming solar radiation: 100% Reflected by the atmosphere: 6% : Absorbed by â¦ the atmosphere: 16% Continuing incoming solar radiation: 78% Reflected by clouds: 20% : Absorbed by clouds: 3% Continuing incoming solar radiation: 55% Reflected by the earth's surface: 4% : Absorbed by the earth's surface (lands and oceans): 51% (Source: NASA.)
The first factor, energy received, depends on the planet's distance from the Sun and its albedo (A), the fraction of light reaching the planet that is reflected away and not absorbed. The albedo is 0.0 if all the light is absorbed and 1.0 for a if all the light is reflected.
