Document Summary
Key concepts: water, hydrologic cycle, hydrology, ocean currents, oceans, gyres, upwelling and downwelling, thermohaline circulation, precipitation, rain gauge. Downwelling and upwelling: downwelling, cold, salty water is dense and sinks, upwelling, less dense water moves up, replaces advected water. Hydrological or water cycle: oceans are vital. October 17: provides most water vapor, influences general circulation of the atmosphere, saltwater, not drinkable, hydrology, study of water at or below earth"s surface, freshwater. Hydrologic cycle: figure 9. 1, combine evaporation and transpiration we have 100, water vapor from land to ocean and ocean back to land. Types of precipitation: table 9. 1, dew, fog-drip, drizzle (mist, like in england- always damp, hail, frozen precipitation, rain, water drops, snowflakes, snow grains. Rain gauge: measures precipitation by depth, weight, or volume. Iii: windshield prevents under catch (precipitation not falling vertically, windshield is there to make sure that the cylinder gets the proper amount of water.
