Term
Watershed
Definition
An area where all water collects into one body of water
Term
Stormwater/Run-off
Definition
Water that does not sink in ground after a storm
Term
Surface Water
Definition
Water found on Earth's surface; water found in lakes, streams, rivers, etc.
Term
Groundwater
Definition
Water found underground
Term
Erosion
Definition
Movement of sediment (soil) by wind
Term
Sediment
Definition
Dirt
Term
Estuary
Definition
A body of water where fresh and salt water mix
Term
Tributary
Definition
A body of water that flows/empties into a larger body of water
Term
Sediment barrier
Definition
Sediment filter sock used to prevent sediment from flowing into streams
Term
Retention pond
Definition
Man-made pond that traps sediment and storm water
Term
The 3 purposes of Retention pond
Definition
1. Traps storm water and allows it to sink underground

2. Traps sediment

3. Prevents storm water from rushing into streams causing erosion
Term
Impervious Surface
Definition
Water cannot penetrate

True or false: The Chesapeake Bay watershed ranges as far North as New York and as South as Virginia.
Definition
True
Term
True or false: A Retention pond is a man-made pond.
Definition
True
Term
The Chesapeake Bay....
Definition
Is the nation's largest estuary
Term
What are the 2 theories of how the Ch. Bay formed?
Definition
1) Meteorite hit bay
2) Glaciers melted raising sea level

How large is the Chesapeake bay watershed?
Definition
64,000 square-miles ranging as far North as New York and as far South as Virginia
Term
What is a piece of land that drains fresh water to the Bay?
Definition
A Watershed. States within the Chesapeake bay watershed's boundaries include New York, Pennsylvania, Delaware, Maryland, West Virginia, and Virginia.
Term
When Fresh water reaches the Chesapeake, it mixes with salt water from the Atlantic Ocean to create what kind of water?
Definition
When Salt and Fresh water join together, it creates Brackish water.
Term

Term
What are the 4 main functions of a marsh?
Definition
1) Provide food
2) Provide habitat
3) Prevent flooding for areas
4) Filtration system for the bay's water
Term
How does a wetland filter water?
Definition
Sediments and pollutants which wash from land into the water are trapped by the plants found in wetlands
Term
How does a marsh minimize the effects of erosion?
Definition
Wetlands help minimize the effects of flooding by protecting shoreline environments from erosion
Term
What does a wetland provide for migratory birds?
Definition
1) Food
2) Resting areas
Term
What is Salinity?
Definition
Salinity is the amount of salt contained in a given sample of water.
Term
How is Salinity measured?
Definition
Saliniy is measured in parts per thousand, or "PPT"
Term
What is the range of salinity in the Ch. Bay?
Definition
In the Ch. Bay, brackish water is created. The salinity in brackish water can range anywherefrom 1 to 29 ppt.
Term
Whta are the three factors that effect salinity?
Definition
1) Location
2) Time of year
3) Depth of water
Term
Where are the salinity levels the lowest in the Ch. Bay?
Definition
The salinity levels are the lowest in the Upper Bay, just below the powerful freshwater inflow of the Susquehanna River.
Term
The salinity levels can determine what about organisms?
Definition
The salinity levels can determine what types of species of plants and animals are found in a specific area.
Term
True or False: 1 of the 3 factors that effect salinity is sediment.
Definition
False
Term
True or False: The salinity levels can determine what types of species of plants and animals are found in a specific area.
