GEOG 2050 : Final Exam Notes
Document Summary
Objectives: water on earth, distribution of water, unique properties of water, hydrogen bonding, heat properties, humidity and dew point, atmospheric stability, clouds and fog, types. Water on earth: as a planet forms, water from within comes to the surface and outgasses. 3 evolutionary phase): outgassing: continuing process where water and water vapor emerge, worldwide equilibrium, water most common compound on the surface of earth. Water phases: solid-ice, less dense than liquid water, expansion of ice, gas-vapor. Iceberg: invisible, compressible, liquid water, takes shape of container (non-compressible, flows under gravity, greatest density at 4 degrees c (39 degrees f) Instruments for measuring humidity: hair hygrometer, sling psychrometer. Saturation: saturation: the max amount of water that can exist in the atmosphere as a vapor at a given temperature, 100% relative humidity. Step one: an air parcel is. : warm low density, cold higher density. Step two: 2 opposing forces: upward buoyant force, downward gravitational force.
