Base your answers to questions 1 through 3 on the three diagrams below and on your knowledge of Earth
science. The diagrams represent stages in the formation of a large depositional feature formed as a river
deposited sediment over time in the ocean. Letter A represents a location in the ocean.
1. Identify the largest particle diameter of sediment that can be carried by the water current at location A, if the
water has a velocity of 0.05 cm/s.
2. Describe the arrangement of the sediments deposited where the river enters the ocean.
3. State the name of this large depositional feature forming in the ocean.

Base your answers to questions 4 through 8 on the map below, which shows a meandering stream as it
enters a lake. Points A through D represent locations in the stream.
4. Deposition is affected by particle density. On the grid, draw a line to show the relationship between particle
density and settling rate.
5. The stream velocity at point C is 100 centimeters per second and the stream velocity at point D is 40
centimeters per second. Identify one sediment particle most likely being deposited between points C and D.
6. Describe how the size and shape of most pebbles change when the pebbles are transported in a stream over a
great distance.
7. State the relationship between stream velocity and the size of the sediment the stream can carry.
8. Draw a cross-sectional view of the general shape of the stream bottom between points A and B. The water
surface line has already been drawn.

9. Base your answer to the following question on the diagram below, which shows igneous rock that has
undergone mainly physical weathering into sand and mainly chemical weathering into clay.
Compare the particle size of the physically weathered fragments to the particle size of the chemically
weathered fragments.
Base your answers to questions 10 through 12 on
the block diagram below and on your knowledge of Earth science. The diagram represents a meandering
stream. Point A represents a location within the meandering stream. Arrows represent the direction of
stream flow.
10. Explain why rock particles transported by the stream often become more rounded.

13. The symbols representing four sediment particles are shown in the key below. These particles are being
transported by Sandy Creek into Lake Ontario. On the cross section below, draw the symbols on the
bottom of Lake Ontario to show the relative position where each sediment particle is most likely
deposited.
14. Explain why sediments are deposited when Sandy Creek enters Lake Ontario.

Base your answers to questions 15 and 16 on
the data table below, which shows the diameters of three particles, A, B, and C, made of the same uniform
material. These particles were carried by a stream into a lake.
15. Explain why the particles are deposited after the stream enters the lake.
16. The cross-sectional diagram below, shows the stream entering the lake. On the diagram, indicate the
expected pattern of deposition of the three particles by placing the letters A, B, and C in the appropriate
boxes along the lake bottom.

17. Base your answer to the following question on the diagram below, which shows a clear plastic tube contain
ing water and a beaker containing a mixture of rounded quartz grains of different sizes.
When the rounded quartz grains are poured all at once into the tube, the grains will settle to the bottom of
the tube. On the cross section provided above, draw the approximate grain sizes and pattern of arrangement
of the rounded quartz grains at the bottom of the tube.
18. New York States Adirondacks are classified as a mountain landscape region. Describe one bedrock
characteristic and one land surface characteristic that were used to classify the Adirondacks as a mountain
landscape region.

streams with equal volumes.
Explain why the outside of the curve of a meandering channel experiences more erosion than the inside of
the curve.
20. Base your answer to the following question on the geologic cross section shown below, which shows the
surface of a landscape region in the southwestern United States and indicates the age, type, and thickness
of the bedrock.
Which New York State landscape region has surface bedrock of the same geologic age as the surface
bedrock shown in this cross section?

Answer Key
Pre-Mid Year Short Answer Review
1.
any value from 0.0008 9.
cm to 0.001 cm
2.
— Larger particles are
deposited in shallow
water and smaller
particles are carried
farther from the shore.
— horizontal
sorting/biggest to
smallest — boulders,
pebbles, sand, silt,
clay/decreasing order
of sizes — The
sediment is sorted. —
The sediment is
arranged in beds or
10.
layers/vertically
sorted. —
Higher-density
particles are deposited
first.
3.
delta or any specific
type of delta
4.
11.
12.
5.
pebbles or sand
6.
- Size: The pebbles
become smaller. Shape: The pebbles
become rounder.
7.
Examples: – a direct
relationship – As the
stream velocity
increases, the stream
can carry bigger
sediment.
8.
– The physically
16.
weathered sediments
are larger in particle
size than the
chemically weathered
particles. – The sand
fragments are larger
17.
than clay fragments. –
The sand fragments
range from 0.006 cm
to 0.2 cm in diameter 18.
and the clay
fragments are less
than 0.0004 cm in
diameter.
– abrasion/friction
between the particles,
– bouncing and
rolling along the
stream bottom, –
Particle collision
breaks off pieces. –
Particles are
weathered.
– Stream velocity:
increases, gets faster,
becomes greater –
Rate of erosion:
increases, there is no
more erosion
19.
Responses include,
but are not limited to:
Stream velocity is
greater on the outside
of the meandering
channel; Stream flow
is slower on the inside
of the meandering
channel; Water is
moving faster on the
outside of a meander
curve
20.
Newark Lowlands
– pebbles
13.
14.
15.
–Water velocity
decreases, causing
some sediment to be
dropped. –The stream
slows down as it
enters the lake.
Bedrock
characteristics: – The
Adirondacks have
faulted, folded, and
deformed bedrock. –
The Adirondacks
have intensely
metamorphosed
bedrock. – The oldest
bedrock is near the
center of the
Adirondacks.
Land surface
characteristics: – The
Adirondacks have
high elevations. – The
Adirondacks have
steep slopes. – The
Adirondacks are a
partially eroded dome.
Examples: – The

decreases.
