What is the purpose of the items shown in these pictures?
they make water slow down and drop sediments
they allow water to infiltrate the ground more easily
they keep water out of storms drains to reduce erosion of the pipes
What do these pictures have to do with erosion?
they allow more water to infiltrate, which means less runoff
they are materials that make water go somewhere to be managed
this pavement is made of materials too large for water to move
Which stream has the lowest capacity?
A
B
C
D
Which stream is most likely to cause the greatest amount of erosion?
A
B
C
D
In which watercourse is deposition most likely to occur?
A
B
C
D
Which of the following statements is true about erosion in this picture?
erosion will be low because the amount of water is low
erosion will be high because the gradient is high
erosion will be low because the water is moving slow
What is bad about this picture?
sediments are going into the storm drain, which could clog it up
the sediments are going to change the color of the pavement
too much water is going into the storm drain, which will kill plants
Identify the vocabulary term shown here
rock bag
gabion
rip rap
silt fence
This is the Mississippi river, where the water is not moving very fast. How can this river cause so much erosion?
the water is very warm
there is a large amount of water
the gradient of the land is very high
The pipes/drain shown in this picture come straight from the roof of the house and lead to the street. What does this have to do with erosion?
the drain moves water directly to the street so it cant pick up sediements
the drain helps water to infiltrate the ground more
the water runs underground, which cools the water
What could explain how a watercourse like the one shown in picture could have moved a sediment so large like the boulder circled?
the water must be very warm
the river probably had more water in it at one time
the water must be extra slimy, allowing the rock to slide more easily

water screen
permeable dam
sediment screen

break water
groyne
silt fence
Identify the vocabulary term shown in these pics
wave dam
groyne
breakwater
sand retention wall
cobble

suspension
ventifact
chattermarks
plucking
ablation
deposition
groyne
retaining wall
sand trap
breakwater
ablation and sedimentation
traction and saltation
suspension and creep
Identify the vocabulary term shown in these pictures
bed load
suspended load
traction and saltation
sedimentation
shore plowing
beach nourishment
sediment sculpting
Which of the following statements would describe why you dont see much erosion in this picture
the ground is flat, so the water wont move very fast
there are plants alongside the stream that help to hold the soil
there is not much water in this stream
all of these would result in little erosion
Why would you coat a hillside in concrete?
to prevent water from even touching any material that could be moved
to make water move faster
to allow more water to infiltrate the ground
The two factors that most determine erosion by water are...
density and temperature
amount of water and speed
soil type and velocity
temperature and discharge

What is a disadvantage of using the plant in this picture to control erosion?
it only grows in dry times
it removes vital nutrients from the soil
it will grow out of control
it wont grow on steep slopes
A
B
C

Which location would likely have the greatest amount of wind erosion?
A
B
C
D
A
B
C
D
Which of the following is NOT a disadvantage of the process shown in the picture?
it disrupts the natural movement of sand
it is expensive
it will have to be repeated
it lowers the water temperature
Which of the following explains why there is so much erosion damage at this location here in GA?
there is a very steep drop, so water will move fast
we get a lot of rain in our area
there are lots of impervious surfaces, which will cause more runoff
the ground is clay, which will move easily
all of the above explain why there is so much erosion damage
In Hawaii, on this newly formed beach, why do you suppose they make a point to plant these new trees?
they need shady areas for people when they visit
they want trees to help hold the sand in place
the trees will help to raise temperatures and decrease precipitation
they want some green in the pictures to look pretty with the black sand
What does the Big Creek Greenway have to do with erosion?
it is where water moves the fastest and picks up the most sediments
this is where we want extra sediments to be dropped
it allows water to speed up and take sediments to the river faster
Why would you expect a lot of erosion in this picture from the Midwest?
It is likely windy here because its in the Midwest
there are no plants over most of the ground
the ground is flat, so there is nothing to stop the wind
all of the above
cobble
pebble
boudler
none of the above

The mixture of material that is picked up and moved by a glacier is called...
loess
ice load
till
none of the above
What is meant by an erosional landform?
any shaping of the land caused by sediments
a landform that is the result of material being moved
a type of landform that is lowered in elevation
a landform that is the result of natural processes
A sandbar in river would be an example of a ___ landform because it is the result of sediments being dropped and piling up.
weathered
elevated
depositional
sedimentary
Why are caves not as common in the western USA?
there is too much granite there
it rains much less in the west
the temperatures are way too high
The elevation is much too low
Caves and sinkholes are likely to form in which type of rock?
granite
limestone
sandstone
marble
A sinkhole forms when..
the acidity of groundwater becomes too low
the water table rises enough to push sediments to the surface
heavier sediments replace lighter sediments underground
groundwater dissolves rock underground until it collapses
What state is known for having a lot of sinkholes?
Florida
Texas
California
Colorado
Land subsidence occurs when…
it rains a lot and the water table rises, pushing elevation up
too much water is taken from the ground by wells and the ground drops
sediments underground settle due to increased rain
water becomes too acidic and will dissolve bedrock
What is the difference between hills and mountains?
mountains are higher
hills have flat tops
hills have steep sides
there is no difference
Valleys tend to be either __ or __
deep, wide
soft, hard
U shaped, V shaped
north, south
Meanders are found in which type of river?
wide
slow moving
steep
hot
Why does GA have so many barrier islands?
it is very close to the equator
the trade winds reduce wave action
there are lots of rivers constantly dumping sediments into the ocean
the ocean water is cold here, which slows movement of sediments
In which state would you most likely find a fjord?
Florida
California
Alaska
Hawaii
