A river enters a lake, slows, and deposits sediment. Which landform is most likely to develop?

  1. A

    Where a stream leaves a steep, confined valley and spreads over flatter ground

  2. B

    Where a river enters a standing body of water and slows

  3. C

    Where wind moves sediment across a dry surface

  4. D

    Where a river current weakens within its channel

A stream exits a steep, narrow valley and spreads across flatter ground, where it loses energy and drops sediment. What landform does this describe?

  1. A

    An alluvial fan

  2. B

    A delta

  3. C

    A beach

  4. D

    A dune

Which statement correctly describes how beaches and dunes form?

  1. A

    Rivers build both landforms by depositing sediment in standing water.

  2. B

    Ice sorts sediment along coasts, while gravity builds dunes on dry surfaces.

  3. C

    Waves redistribute sediment along coasts, and wind redistributes sediment across dry surfaces.

  4. D

    Groundwater cements sediment into both landforms.

A stream slows and begins dropping some of its sediment load. What change most directly explains this deposition?

  1. A

    The transporting agent gains energy and carries a larger load.

  2. B

    The transporting agent loses enough energy that it can no longer carry some of its load.

  3. C

    The sediment grains become cemented before they are transported.

  4. D

    The sediment changes composition as soon as it enters a stream.

As a stream slows, which settling pattern is most consistent with the behavior of finer sediment?

  1. A

    Fine silt and clay may remain suspended longer and settle in quieter water farther downstream.

  2. B

    Fine silt and clay always settle before gravel because they are smaller.

  3. C

    All grain sizes settle at the same distance from the source.

  4. D

    Fine silt and clay can settle only after groundwater cements them.

A debris flow stops suddenly and leaves a deposit containing gravel, sand, and finer particles together. How is this deposit most likely sorted?

  1. A

    A deposit made of grains that are all roughly the same size

  2. B

    A deposit formed only by repeated wind transport

  3. C

    A deposit in which every grain settles in a separate layer

  4. D

    A deposit containing a wide range of grain sizes

08

A deposit formed as transport energy decreases has coarse grains at its base and finer grains toward its top. What does this pattern describe?

  1. A

    Fine grains at the bottom, with progressively coarser grains above

  2. B

    A uniform mixture of grain sizes throughout

  3. C

    Coarse grains at the bottom, with progressively finer grains above

  4. D

    Alternating layers of only gravel and only clay, regardless of transport energy

Which feature can develop where currents weaken within a river channel and deposit sediment?

  1. A

    A river bar

  2. B

    A floodplain

  3. C

    A sediment bed

  4. D

    A poorly sorted deposit

12

1 point

Select all statements supported about sediment sorting.

  1. A

    A well-sorted deposit contains grains of roughly similar size.

  2. B

    A poorly sorted deposit contains a wide range of grain sizes.

  3. C

    Sorting by itself identifies the environment where a deposit formed.

  4. D

    Persistent waves or wind can sort sediment by repeatedly moving some sizes and leaving others behind.

13
Choose all
1 point

Select all changes that can lead to successive sediment layers differing in grain size or composition.

  1. A

    A river shifts its course.

  2. B

    A flood subsides.

  3. C

    The strength of waves changes.

  4. D

    The sediment is buried, so the existing layers must become identical in composition.

14
True or false
1 point

True or false: A deposit's sorting can provide clues about how sediment was transported, but sorting alone does not identify the depositional environment.

  1. A

    True

  2. B

    False

15
True or false
1 point

True or false: If successive sediment layers differ in grain size, that difference can be evidence of changing transport or depositional conditions.

  1. A

    True

  2. B

    False

A deposit contains successive layers that differ in grain size or composition. Explain what this pattern can suggest about the conditions under which the sediment accumulated, and why the pattern alone may not identify a specific depositional environment.
