GGR100H1 Study Guide - Midterm Guide: Spatial Analysis, Thermosphere, Aurora
Document Summary
Ionosphere: outer layer, extends through thermosphere and mesosphere. Important to broadcast communications (tv, radio wavelengths): ozonosphere: portion of atmosphere that contains increased level of ozone (o3). Absorbs wavelengths of uv rays, converts to heat energy, and reradiates as long wave, warming the stratosphere. Uv rays, protecting earth"s surface and inhabitants: levels of the atmosphere by temperature, thermosphere: 80 to 480km above surface. Increased motions of particles cause kinetic energy, but density of molecules is low so little heat is transferred and produced: mesosphere: 50 to 80km above surface, coldest part of atmosphere, Receives meteors and cosmic dust, and burns up. Noctilucent clouds occur: stratosphere: 18 to 50km above surface, temperature increase from -57c to 0c at stratopause. Where volcanic particle float to: troposphere: final layer, home of biosphere, where al weather occurs, and planes fly. Causing temperature inversion, global warming: what is insolation? i.
