2. Where is the river mouth of the major rivers? Missouri River Mississippi River Arkansas River Ohio River http://thelargest.net/river-in-the-united-states/mississippi-river-system A river mouth or stream mouth is a part of a river where it flows into the sea, lake, reservoir or ocean. At the mouth of a river a delta is formed resulting from sediment deposition. Gulf of Mexico

5. A chemical plant in NC leaked great amounts of toxic chemicals in the Yadkin River. What other river would also be poisoned by the toxic chemicals? Roanoke river Pee-Dee River Toxic chemical spill

Most rivers flow downstream ( gravity), some flow horizontally ( left and right ) and others even flow upstream. What!?

A meander is a bend in a river. 6. What are Meanders and Oxbow Lakes? An oxbow lake is a U-shaped body of water that forms when a meander is cut-off from the river. A meander is a bend in a river. http://www.geo.uu.nl/fg/palaeogeography/results/fluvialstyle

8. What is a watershed? A watershed is an area of land where all precipitation that falls on it drains to a river  http://www.oldhamcounty.net/Curry_Fork/watershed_Glossary.htm

The land that separates each watershed is called a divide. 9. What is a watershed divide? The land that separates each watershed is called a divide. Divide http://www.oldhamcounty.net/Curry_Fork/watershed_Glossary.htm

Watershed Divides http://nationalatlas.gov/articles/geology/a_continentalDiv.html

Watershed receives water from precipitation. Watershed to river Divide High land within the watershed. River flow downstream. http://www.oldhamcounty.net/Curry_Fork/watershed_Glossary.htm Percolation or infiltration

10. A watershed is: Water around a given land area A stream that flows into a lake A series of streams that connect The total land area that drains into a stream or river system

11. What separates two watersheds? A. divide B. aquifer C. mountain D. river basin

An estuary is the channel of a river where it nears the sea, with a mixing of fresh water and salt water happen. There are a lot species that consider the estuary as their habitat. freshwater Brackish water Ocean tides causes salt water to rise and mix with freshwater. http://ian.umces.edu/imagelibrary/displayimage-6963.html http://www.co.palm-beach.fl.us/erm/lakes/estuarine/lake-worth-lagoon/urban-estuary-cd/gallery.htm

12. Why are estuaries important to the environment? Estuaries provide us with ample freshwater. Estuaries are nurseries and habitat for many species.

13. What is the difference between a lake and a reservoir? a lake is man made while a reservoir(dam) was formed by glaciation. B. A reservoir(dam) is man made while a lake was formed by glaciation.

14. How are watersheds and rivers polluted? http://www.oldhamcounty.net/Curry_Fork/watershed_Glossary.htm Watersheds and rivers are polluted by non-point source pollution.

Riparian buffers are important for good water quality. Non-point source pollution is removed from runoff by plants before reaching the river or stream http://blog.epa.gov/science/2012/09/around-the-water-cooler-riparian-buffers/

Sediments and pollutants pollutes the river or stream. River Riparian buffers are important for good water quality. Riparian zones help to prevent sediment and pollutants from reaching a stream. Riparian buffers include a native grass or herbaceous filter strip along with deep rooted trees and shrubs along the stream. NO riparian buffer Corn farm Runoff with sediments and excess fertilizers. http://www.bae.ncsu.edu/programs/extension/wqg/sri/riparian5.pdf http://commons.wikimedia.org/wiki/File:Little_Calumet_River_with_no_riparian_buffer_just_above_Heron_Rookery_2011-08-07.JPG Sediments and pollutants pollutes the river or stream. River

prevent erosion of loose soil from crops 15. A riparian buffer is an area of vegetation found near a stream. What benefit could this provide in an agricultural area? prevent erosion of loose soil from crops reduce non-point source pollution of surface water
