Measurement Not all of the direct and diffused radiation available at the Earth's surface is used to do work (photosynthesis, creation of sensible heat, evaporation, etc. On average, about 15% of incoming solar radiation is absorbed by atmospheric molecules such as water vapor, oxygen and small particulates (aerosols). What does. The global solar energy that reaches the earth's surface is 10,000 times greater than the energy currently consumed by all of humanity. Cloud cover, air pollution, latitude of a location, and the time of the year can all cause variations in solar radiance at the Earth's surface. Dark colored objects, such as asphalt, absorb radiant energy faster than light colored objects. The Earth absorbs most of the energy reaching its surface, a small fraction is reflected. The surface of Earth is absorbing solar radiation. 7 What happens to the sun's energy when it reaches Earth quizlet? The sun emits a vast amount of energy, which travels across space in the form of short-wave radiation. The intensity of solar radiation is largely a function of the angle at which the Sun's rays strike the Earth's surface, called the angle of incidence. The term solar radiation is a generic concept, but it is not quantified to any magnitude. Several factors influence the amount of solar radiation reaching the Earth's surface and the amount of radiation leaving the Earth . 8 Is the incoming solar energy intercepted by the Earth? As the Sun's rays spread out into space the radiation becomes less intense and by the time the rays reach the edge of the Earth's atmosphere they are considered to be parallel.

The solar constant is. 8 How is solar radiation sent back into space? However, since the Earth is much cooler than the Sun, its radiating energy is much weaker (long wavelength) infrared energy. 9 How does energy released from the sun reach Earth? Solar Radiation. Insolation is the amount of solar radiation that reaches the earth's surface through shortwaves. We are assuming that 184 units of solar radiation reaches Earth's surface and that the present-day configuration of land covers reflects some of that radiation back into space. The sum of the diffuse and direct solar radiation is called global solar radiation. The amount of energy reaching the surface of the Earth every hour is greater than the amount of . This intense solar radiation as it is known in physical geography originates in the sun's core and is eventually sent to Earth after convection (the vertical movement of energy) forces it away from the sun's core.
