Document Summary
Ecosystem respiration includes both the respiration of carbon above the surface and from soil. These processes form the foundation for ecological processes on surface. Eesa01: earth"s climate is all about energy fluxes and the balance between outgoing and incoming energy, energy cannot be created or destroyed, just transferred. Earth is open to energy: insolakon is energy received from the sun, insolakon is shortwave radiakon, shortwave radiakon inputs include: ultraviolet light (uv) Near- infrared wavelengths: insolakon drives most processes on earth, insolakon and earth"s klt and rotakon produce the daily, seasonal, and annual palerns of day length and climate. (incoming solar radiation). Wavelength: electromagnekc radiakon travels in waves ; the distance between wave peaks is wavelength. Wien"s displacement law: wavelength at which maximum energy radiakon occurs is inversely related to surface temperature. T = temperature of surface in degrees k. Max of sun (6000 k); of earth (290 k)? (absolute zero = 0 k; 0 c = 273. 15 k)
