2. Saltwater Freshwater Makes up 97% of the Earth’s supply of water.
Comes from the ocean.
Undrinkable.
Makes up 3% of the Earth’s supply of water.
Some of it is frozen while some is in the ground (groundwater) and the rest is in rivers and lakes.
Drinkable.

3. What is freshwater ?
Freshwater is essential for living things to grow, reproduce, and carry out important process.
H2O- Chemical formula used to represent water’s unique structure which is made of two hydrogen (H) atoms bonded with one oxygen (O) atom to form water (Polar molecule).
Water is a universal solvent. Many substances dissolve it in.

4. Aquifer
Layer of rock or sediment that holds water and can range in size from a small pond to an area of several states.
Artesian Well- A well, which water rises because of pressure within an aquifer

5. Where is the Freshwater?
Glaciers:
Huge mass of and snow that moves slowly over land formed in areas where more snow falls each year than melts.
Also icebergs (broken, or glaciers that have calved into oceans)
Groundwater:
Comes from precipitation that soaks into the ground between particles of soil and spaces in layers of rock

6. Porosity
The percent of the total volume of rock or sediment that consists of pore spaces.
The amount of groundwater that can be stored depends on porosity
Groundwater moves by twisting and turning through these spaces
Groundwater moves more slowly when pores are smaller

7. Saturated Zone
Area of permeable rock or soil that is totally filled, or loaded with water.
Water Table- Top of saturated zone.

8. Permeability Comparison
It would take 2 minutes for water to travel through gravel.
It would take 2 hours for water to travel through sand.
It would take 200 days for water to travel through silt.
It would take 200 days for water to travel through clay.

9. The Water Cycle Evaporation- Liquid to a gas.
Condensation- Gas to a liquid.
Precipitation- Water released from clouds.
Infiltration- Water moves and is soaked into rock and soil.
Transpiration- Plant sweat.

10. Natural Springs, Geysers, and Wells
A natural spring is a place where ground water bubbles or flows out of cracks in the rock.
A geyser is a type of hot spring which begins to rise through narrow passages being forced out by heated gases and steam from below.
A well is a man-made hole drilled below the water table in order to obtain groundwater from an aquifer
An artesian well is a well in which water rises because of pressure within an aquifer.

11. Changing State
Water can change into all states of matter (solid, liquid, gas) within Earth’s temperature range.

12. Ponds and Lakes
Forms when water collects in hollows and low-lying areas of lands

13. Wetlands Area of land that is covered with a shallow layer of water.
Coastal Wetlands- Mixture of fresh and salt water, such as estuaries, salt marshes and mangrove forests.

14. River System
A river and all its tributaries, or small streams, together with the watershed and the land.

15. River Basin
Portion of land drained by a river and its tributaries (branches).
There are 17 river basins and located in North Carolina. The largest river basin is Cape Fear, while Savannah is the smallest.

16. North Carolina’s River Basins
Tributaries, lakes, reservoirs, ground water etc, are usually located in river basins that f

17. Watershed
A watershed is used to describe a smaller area of land that drains to a smaller stream, lake, or wetland
