1
Hydrosphere water water everywhere
2
The water cycle
3
Evaporation Water turns from a liquid to a gas Water moves as vapor into the atmosphere
4
Transpiration water vapor enters the atmosphere from plants Water comes up through the xylem and out through the stoma of leaves
5
Sublimation Water turns directly from a solid to a gas Freeze drying Can happen when snow seems to disappear without melting
6
Condensation water turns from a gas to a liquid cloud formation dew
7
Transportation movement of water around the planet surface water (runoff) underground in the atmosphere as vapor moves in plants (transpiration)
8
precipitation water falls from the atmosphere rain, snow, sleet, hail, mist, and fog
9
deposition water changes directly from vapor to solid without a liquid phase high altitudes rare
10
percolation / infiltration water filtered through porous materials such as bedrock and soil water moves into groundwater
11
flow collection of moving water snowmelt rainwater groundwater all water flows downhill
12
Plant uptake Plants take groundwater up through the roots first part of transpiration
13
River Basins all the land surface dissected and drained by many streams and creeks flowing downhill into one river sends water out to the sea
14
NC river basins 17 designated river basins in NC 5 western basins drain to Gulf of Mexico Hiwassee, Little Tennessee, Watauga, French Broad, and New 12 flow to the Atlantic 4 contained in NC alone Cape Fear, Neuse, White Oak, and Tar - Pamlico
15
NC River Basins
16
Watersheds
17
Aquifers underground layer of saturated rock in which water can easily move used as wells
18
water table level below where the ground is completely saturated varies with seasons changes with time varies with location
19
groundwater and flooding groundwater close to the surface can cause chronic problems localized high water tables can cause basement flooding in one house and the house next door can be dry When the water table is full, water can not percolate into the ground
20
Ocean Currents Thermohaline circulation
21
Surface currents Develop from friction between ocean currents and wind Short, affect small areas Result of local or seasonal influence
22
Gyres Circular moving current systems 5 main North Pacific, South Pacific, North Atlantic Gyre, South Atlantic, and Indian Ocean gyre
23
Coriolis Effect Deflection of currents away from their original source due to Earth’s rotation Right in the Northern Hemisphere, Left in the Southern Hemisphere coriolis effect coriolis effect explained!
24
Currents on Climate Heat is transferred from water Currents from low latitude regions bring heat in the water to higher latitudes
25
Upwelling Rising of cold water from deeper layers to replace warmer surface water Wind induced Occurs when winds blow from equator parallel to the coast Brings up greater concentrations of nutrients Upwelling demoUpwelling importance
26
Density currents Vertical currents of ocean water resulting from density differences INCREASE in density could result from: Higher salt concentration Lower temperature
27
High latitudes Water involved with deep-ocean density currents begins in high latitudes Once it sinks its temperature and density remain mostly unchanged
28
evaporation Increased salinity due to evaporation can cause density currents Happens in the Mediterranean Sea thermohaline circulation
