GEOG 2050 : GEOG 2050 Exam 2
Document Summary
Solar radiation varies: output from sun, distance of earth from sun, daily, seasonally, latitudesvcf65. Atmosphere functions as a filter: absorbs, gamma rays, x rays, uv, allows visible to reach earth"s surface. Energy pathways: short wave energy from the sun, long wave energy from earth. These particles can either: passage of energy through atmosphere or water. Insolation in the atmosphere encounters gases, dust, clouds and smoke. Insolation input- all radiation received at earth"s surface direct and indirect. ~ 50 % of insolation makes it to the earth"s surface. Scattering- changing direction of light"s movement, without altering its. Absorption- the assimilation of radiation by molecules of matter. The conversion of energy from one form to another: scatter, absorb, reflect, refraction wavelength or scattered. Reflection- insolation (light) is bounced off a surface without being absorbed. Refraction- change in speed and direction of light. Occurs when insolation is not absorbed, but is bounced in all directions.
