GEOG 2050 Chapter : Beginning Of CH 4
Document Summary
Energy essentials: energy balance in the troposphere, energy balance at earth"s surface. Energy pathways and principles: shortwave energy in from the sun, long wave energy out from earth, transmission, passage of shortwave or long wave energy through atmosphere or water. Insolation input: all radiation received at earth"s surface direct and indirect. Scattering: changing direction of light"s movement, without altering its wavelengths. Refraction: change in speed and direction of light. Absorption: the assimilation of radiation by molecules of matter and its conversion from one form of energy to another + absorption, any insolation that is not part of the 31% reflected from. It is then converted by plants in photosynthesis or long wave radiation: land and water ( ~45%, atmosphere (~25%) Heat transfer: conduction, convection, molecule to molecule transfer, energy transferred by movement, advection, horizontally dominant movement (wind, radiation, energy traveling through air or space.
