GEOG 2050 : Geog Exam 2 Study Guide
Document Summary
Define the stefan-boltzmann law: the amount of energy that a blackbody emits is proportional to the fourth power of its absolute temperature. Define wein"s law: the wavelength of the peak radiance decreases linearly as the temperature increases. Give two examples of each: conduction: molecule to molecule transfer of heat, convection: energy transfer through physical mixing involving strong vertical motion (heat coming off coffee, advection: physical mixing involving strong horizontal motion (wind and coffee) Why is the sky blue: when insolation passes through the atmosphere, after rayleigh scattering the only color left is blue, sunset: sun at lower position, has more atmosphere to pass through. What is refraction and how is it different from scattering: refraction is the bending of light as it travels through a medium: e. g. rainbows. Energy pathways (direct, diffuse, albedo, reflection: direct, diffuse, albedo: the reflective quality of a surface, reflection:
