Term
watershed
Definition
area where all water drains into all bodies off water
Term
stormwater/run-off
Definition
rain that hits the ground and doesn't sink right away
Term
surface water
Definition
water above ground such as lakes, streams, rivers, and oceans
Term
groundwater
Definition
water underground
Term
erosion
Definition
when sediment/dirt is moved by wind and water
Term
sediment
Definition
dirt
Term
estuary
Definition
a body of water where fresh water and salt water mix
Term
tributary
Definition
a body of water that empties into a larger body of water
Term
sediment barrier
Definition
barrier used to control silt and sediment
Term
retention pond
Definition
pond that catches runoff from higher elevation areas
Term
imperious surface
Definition
many artificial surfaces like pavement and cement
Term
3 purposes for retention pond
Definition
traps sediment
traps storm water so it turns into groundwater
prevents storm water from causing erosion
Term
True of Flase? Groundwater is water running above ground.
Definition
False
Term
True of False? Sediment is dirt.
Definition
True
Term
True or False? A tributary is a larger body of water emptying into a smaller body of water
Definition
False
Term

Definition
Ney York, Pennsylvania, Delaware, Maryland, West Virginia, and Virginia
Term
Chesapeake Bay
Definition
fresh water mixes with salt water from the Atlantic Ocean to create brackish water.
Term
point source pollution
Definition
type of pollution easy to see the source
Term
examples of point source pollution
Definition
smoke stacks and pipes from industry
Term
True or False? Point source pollution is easier to regulate
Definition
True
Term
non-point source pollution
Definition
pollution source not easy to see
Term
examples of non-point source pollution
Definition

Definition
chemicals + water droplets
Term
fertilizers
Definition
abundance of algae
Term
garbage
Definition
destroys habitat
Term
sediment
Definition
covers fish eggs + underwater gasses
Term
turbidity
Definition
cloudiness of water
Term
4 main functions of a marsh
Definition
filtering water into the bay
protect nursery areas for aquatic animals
provide food and habitat for animals
prevents flooding
Term
wetland filtering water
Definition
sediment gets trapped in the plants and filtered clean
Term
marshes minimizing the effects of erosion
Definition
protects the shoreline environment by stopping the sediment with its plants
Term
wetland providing for migratory birds
Definition
provides food and a resting area
Term
salinity
Definition
the amount of salt in a body of water
Term
salinity measure
Definition
parts per thousand or ppt
Term
range of salinity in the bay
Definition
1 to 29 ppt
Term
three factors that effect salinity
Definition
location, time of year, and depth of water
Term
salinity lowest in the bay
Definition
upper bay and closer to the surface
Term
salinity can determine what about organisms
Definition
where a species would live because of salinity
