Base your answers to questions 1 through 3 on the three diagrams below and on your knowledge of Earthscience. The diagrams represent stages in the formation of a large depositional feature formed as a riverdeposited 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 thewater 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 itenters 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 particledensity and settling rate.

5. The stream velocity at point C is 100 centimeters per second and the stream velocity at point D is 40centimeters 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 agreat 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 watersurface line has already been drawn.


9. Base your answer to the following question on the diagram below, which shows igneous rock that hasundergone 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 chemicallyweathered 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 meanderingstream. Point A represents a location within the meandering stream. Arrows represent the direction ofstream flow.

10. Explain why rock particles transported by the stream often become more rounded.


11. Describe the relative changes in the stream velocity and the rate of erosion that will occur after 2 days ofheavy rainfall.

12. Identify the name of the largest sediment particles that can be transported at point A when the stream'svelocity is 100 cm/s.


Base your answers to questions 13 and 14 on the map below and on your knowledge of Earth Science. The map shows the location of Sandy Creek, westof Rochester, New York. X and Y represent points on the banks of the stream.


13. The symbols representing four sediment particles are shown in the key below. These particles are beingtransported by Sandy Creek into Lake Ontario. On the cross section below, draw the symbols on thebottom of Lake Ontario to show the relative position where each sediment particle is most likelydeposited.

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 uniformmaterial. 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 theexpected pattern of deposition of the three particles by placing the letters A, B, and C in the appropriateboxes along the lake bottom.


17. Base your answer to the following question on the diagram below, which shows a clear plastic tube containing 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 ofthe tube. On the cross section provided above, draw the approximate grain sizes and pattern of arrangementof the rounded quartz grains at the bottom of the tube.

18. New York States Adirondacks are classified as a mountain landscape region. Describe one bedrockcharacteristic and one land surface characteristic that were used to classify the Adirondacks as a mountainlandscape region.


19. Base your answer to the following question on the block diagrams below, which show three types ofstreams with equal volumes.

Explain why the outside of the curve of a meandering channel experiences more erosion than the inside ofthe curve.

20. Base your answer to the following question on the geologic cross section shown below, which shows thesurface of a landscape region in the southwestern United States and indicates the age, type, and thicknessof the bedrock.

Which New York State landscape region has surface bedrock of the same geologic age as the surfacebedrock shown in this cross section?

Answer KeyPre-Mid Year Short Answer Review

1. any value from 0.0008cm to 0.001 cm

2. — Larger particles aredeposited in shallowwater and smallerparticles are carriedfarther from the shore.— horizontalsorting/biggest tosmallest — boulders,pebbles, sand, silt,clay/decreasing orderof sizes — Thesediment is sorted. —The sediment isarranged in beds orlayers/verticallysorted. —Higher-densityparticles are depositedfirst.
