| Do you live near a river basin? | Yes, everyone lives near a river basin |
| What does water treansfer as it moves downstream? | Water transfers bacteria, chemicals, excess nutrients and organic matter as well as carrying and redepositing gravel , sand, silt |
| The quote,"the health of an aquatic ecosystem is directly related to activities on land." refers to an aquatic ecosystem . What is an aquatic ecosystem? | Responces may very. A possible response may be an aquatic ecosystem is an environment which is sufficent to support the lives of various organisms which live in the water |
| How can the flow of stormwater be controlled? | Vegetation buffer |
| When a scientist surveys the microinvertrbrates in a body of water, what is he/she studying? | Animals that lack a backbone and a visible to the naked eye |
| Name 4 ways that citizens are making a difference in their communities | a. Steam Watch b. Urban Stream Renewal c. land conservation d. enviromental education |
| riparian | pertaining to the edges of streams or rivers |
| greenway | open space or connector along a natural corridor (such as a river) used for parks and trails |
| vegatation buffer | a. protect their banks from erosion b. reduce the impact of nonpoint source pollution by trapping, filtering and converting pollutants c.supply food , shelter and shade to fish and other aquatic wildlife |
| what is a floodplain? | is a usually dry area that becomes inundated with water when streams and rivers overflow |
| what is a wetland? | is an area where the water table is at near or above the surface long enough during the year to support long enough during the year to support the growth of specially adopted plants |

| Describe the term vegetation buffer | plants and trees surrounding a river or stream |
| What is sediment | eroded perticles thet wash or blow onto particles |
| How does sediment affect water quality? | large sediment will kill aquatic creatures wreking havoc throughout the food web- from insects to fish to humans |
| Why are more humans vulnerable to flooding? | -alternation of land around rivers changing the path of water -wetlands have been filled -streams have been straightned , paved, and developed - accelerated urban development and land disturbance reducing the land's ability to absorb runoff |
| how has urban development reducing the land's ability to absorb runoff? | For example , a building site 30 yr.'s ago may have been outside of 100-year floodplain might be considering in the middle of the floodplain today |
| what is an point and non-point source? | p.s= you can tell were it's coming from like an pipe or outfall n.p.s= you can't tell were it comes from |
