10. 4. What is the river that passes
Winston Salem?
Yadkin–Pee Dee River Basin is the second largest river basin in North Carolina.
Cape Fear River basin is the largest river basin in NC

12. 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

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

14. 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.

18. 8. What is a watershed?
A watershed is an area of land where all precipitation that falls on it drains to a river 

19. 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

20. Watershed Divides

21. Watershed receives water from precipitation.
Watershed to river
Divide
High land within the watershed.
River flow downstream.
Percolation or infiltration

22. 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

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

24. 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.

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

26. 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.

27. 14. How are watersheds and rivers polluted?
Watersheds and rivers are polluted by non-point source pollution.

28. Riparian buffers are important for good water quality.
Non-point source pollution is removed from runoff by plants before reaching the river or stream

29. 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

Runoff with sediments and excess fertilizers.
Sediments and pollutants pollutes the river or stream.

30. 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

Holy Rosary Church at Karnataka, India, emerges and sinks beneath the waters every year since the construction of a dam in the area in 1960
Church of Old Petrolandia, Brazil, is the only thing left standing after the town was moved to make way for a dam
