topography packet, Satellite Images and Topographic Maps of Texas: An Elevated View, and think back to the rules you
followed when making Fantasy Island.
Streams Worksheet
The map to the right shows the path of a river. The arrow shows the direction the river is flowing. Letters A
and B identify the banks of the river.
1.______The water depth is greater near bank A than bank B
because the water velocity near bank A is
(1)
(2)
(3)
(4)
faster, causing deposition to occur
faster, causing erosion to occur
slower, causing deposition to occur
slower, causing erosion to occur
The map to the right shows a meandering river. Points A and B
are locations on the bank of the river.
2.______What are the dominant processes occurring at locations A and B?
(1)
(2)
(3)
(4)
deposition at location A; erosion at location B
erosion at location A; deposition at location B
deposition at both locations A and B
erosion at both locations A and B
3.______ Deposition within a meandering stream usually occurs on the
inside of the curves because the
(1) water velocity decreases
(2) stream gradient decreases
(3) water is deeper
(4) stream is narrower
4.______ A meandering stream deposits most of its sediments on the
(1)
(2)
(3)
(4)
inside of meanders where the stream flows faster
inside of meanders where the stream flows slower
outside of meanders where the stream flows faster
outside of meanders where the stream flows slower
The map to the right shows a meandering stream. Points A, B, C and D
represent locations along the stream bottom.
5.______At which location is the greatest amount of sediment most likely
being deposited?
(1) A (2) B (3) C (4) D
The map to the right shows the bend of a large meandering stream. The
arrows show the direction of stream flow. Letters A, B and C are positions
on the stream bed where erosion and deposition data were collected.
6.______Which table below best represents the locations where erosion and
deposition are dominant and where an equilibrium (balance) exists between
the two processes? (A check mark represents the dominant process for each
lettered location.)
