Document Summary
Amount of atmosphere: perpendicular angle, photons travel through less air than any other angle, in tropics have shorter sunsets b/c they have less surface area of sun, thick atmospheres work kind of as a prism for sunsets. Amount of reflection: something brighter will reflect more photons, sea water absorbs all the photons once it, albedo, 0 100, reflectivity of a surface, average for earth is 30% Ocean heat flow: high latitudes, more heat lost than gained, ice has high albedo, low solar ray incidence, low latitudes, more heat gained than lost, ocean moderates these effects in terms of temperature change. Composition of atmosphere: air we breath, 78% nitrogen, 21% oxygen, 0. 9% argon, 0. 04% carbon dioxide, other trace gasses, heat trapping properties, includes methane, short wave lengths come into earth and long wave lengths. Convection cell (atmospheric circulation cell: rising and sinking air, warm air rises, less dense, cool air sinks, more dense.
