Earth Science: Chapter 7 – Water Water on Earth Quantity Equilibrium: net input/output of water creates a steady balance Hydrologic Cycle: atmospheric components Most of Earth’s water is located in the Southern Hemisphere Water: 97% oceanic (salt) 2.7% fresh water 80% surface 99.7% glacial water 0.3% lakes, rivers, groundwater (potable water) Planet’s Unique Location: water can exist in all 3 states at the same time and temperature Heat Properties: Ice Water Water Vapor Deposition Ice Water Vapor Sublimation Condensation: Warming process Evaporation: Cooling process Water Snow: a depositional process as it is water vapor being converted into ice Gas: contains the highest energy Solids: contain the lowest energy Latent Heat of Vaporization: heat required for evaporation cooling process Latent Heat of Condensation: released heat for condensational warming amountof H O∈theair 2 Relative Humidity: totalwatertheair can potentiallyhold (denominator controlled by temp) 6gal(howmuchis∈thetank) 12 gal Atmospheric Relativity: saturation Ex. Gas tank: 12gal(howmuchthetankcanhold) (50%) 12 gal (100%) OverSaturation: once this occurs in the atmosphere, it causes the formation of condensation in the form of clouds, fog, and dew point in order to try & balance 13gal Ex. 12gal Dew Point: how much the temperature has to drop in order for condensation to occur **Relative Humidity: *Humidity Patterns: inversely related warmer air holds more water because it High temperature = low humidity Low temperature = high humidity expands, therefore more room to hold water (water vapor) Vapor Pressure: weight of water in the air (more in the summer b/c of influence of temp) Measured How? Sling Psychrometer Clouds & Fog Cloud Types & Identification: precipitation (where in atmosphere? L,M,H Fog Advection: fog that moves or rollsin (spooky fog that moves in cemeteries) – coasts & mountains Evaporation: over water bodies Upslope/Valley (Mtn.): cold, dense air that sinks into the valley (reduces visibility) **Radiation: dominant fog on earth (after rain clears out) Atmospheric Stability Adiabatic Processes: Pressure is zero in outer space; rising air expands (balloons); the air is physically doing work to expand & requires energy (heat energy, kinetic energy) – therefore it cools as expansion occurs Descending/Sinking Air: compresses and heats up Adiabatic: change of temperature from expansion and compression ONLY Dry Rate: 10°/km No Condensation Moist Rate: 6°/km with Condensation Environmental Lapse Rate (ELR): Real temperature in the atmosphere Stability in the atmosphere: clouds develop in an unstable atmosphere when air is moved upward the air will return to that position, whereas in an unstable environment there is no balance (similar to a positive feedback system) As the height increases the temperature decreases as the atmosphere thins out and the air pressure drops. **Tropical air masses are hot, yes, but who knows if they are humid.
