GG101 Study Guide - Geomatics, Stellar Atmosphere, Subsolar Point
Document Summary
General model of atmosphere: composition, temperature, and function. Principle substance of atmosphere is air (mix of gases, odourless, and colourless) Exosphere: outer sphere beyond atmosphere, less dense. Air pressure: force per unit area of atmosphere. Homosphere: below hetrosphere extending altitude of 80 km to earth"s surface. Hetrosphere: outer atmosphere in terms of composition. Mesosphere: layer from 50-80 km above earth. Earth revolves around sun, and rotates on its axis. Sub-solar point: position where sun is directly overhead migrates between capricorn and. Angle of axis rotation is staggered 23. 5, without the tilt of earth there would be no seasons. Earth at equinox: spread of daylight is even. Earth at summer solstice: 24 hrs. light and 24 hrs. darkness in southern pole. Wiens law : b=constant, t= surface temperature explains horizontal break. Geomatics relationship of sun and earth (tilt, earth axis, earth rotation) At night condensation releases heat and it warms temperature. Solar radiation is the fuel" for natural phenomena.
