Hydrosphere water water everywhere !
(DO NOT WRITE anything in YELLOW!)
The water cycle
Evaporation Water turns from a liquid to a gas
Water moves as vapor into the atmosphere
Transpiration
water vapor enters the atmosphere from plants
Water comes up through the xylem and out through the stoma of leaves
Sublimation
Water turns directly from a solid to a gas
Freeze drying
Can happen when snow seems to disappear without melting
Condensation
water turns from a gas to a liquid
cloud formation
dew
Transportation
movement of water around the planet
surface water (runoff)
underground
in the atmosphere as vapor
moves in plants (transpiration)
precipitation
water falls from the atmosphere
rain, snow, sleet, hail, mist, and fog
deposition
water changes directly from vapor to solid without a liquid phase
high altitudes
rare
infiltration
water filtered through porous materials such as bedrock and soil
water moves into groundwater
flow
collection of moving watersnowmeltrainwaterGroundwater
all water flows downhill due to gravity
Plant uptake
Plants take groundwater up through the roots
first part of transpiration
River BasinsRiver Basin: all the land surface dissected and drained by many streams and creeks flowing downhill into one river
Watershed: All of the land area whose water drains into a stream system, also called a drainage basin.
Tributary: A stream that empties into a larger river.
sends water out to the sea
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
Of these 4 are contained in NC alone
Cape Fear, Neuse, White Oak, and Tar - Pamlico
NC River BasinsRiver Basins are a portion of large area lands which is
drained by rivers and streams that flow into each other downhill.
Water drainage for the land.
WatershedsWatersheds are basin-like landform defined by
highpoints and ridgelines that descend into lower elevations and stream valleys.
Aquifers
underground layer of saturated rock in which water can easily move
used as wells
water table
level below where the ground is completely saturated
varies with seasons
changes with time
varies with location
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 infiltrate into the ground resulting in flooding.
Contaminant• Everyone needs to be careful about how
they interact with their watershed. Anything someone enter up river will affect people who live down river..
• A substance that is either present in an environment where it does not belong or is present at levels that might cause harmful effects to humans or the environment

• Point Source Pollutions – Originating from a single , identifiable source, such as a discharge pipe from a factory or a sewage plant.
• Non-Point Source Pollution- A contributory factor to water pollution that cannot be traced to a specific spot; for example: pollution that results from water runoff from urban areas, construction sites, and agricultural operations.
• VOC- Volatile Organic Compounds
