Geomorphic Processes Questions

Multiple choice

What is the term for the process by which a river deposits sediment on its floodplain?

  1. Erosion

  2. Transportation

  3. Deposition

  4. Meandering
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Deposition is the process by which a river deposits sediment on its floodplain. Erosion is the process by which a river wears away its bed and banks. Transportation is the process by which sediment is carried downstream by the river. Meandering is the process by which a river forms sinuous bends.

Multiple choice

Which of the following is NOT a factor that influences river channel morphology?

  1. Discharge

  2. Slope

  3. Sediment load

  4. Climate
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Climate is not a direct factor that influences river channel morphology. Discharge, slope, and sediment load are all direct factors that influence river channel morphology.

Multiple choice

What is the term for the process by which a river changes its course over time?

  1. Erosion

  2. Transportation

  3. Deposition

  4. Avulsion
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Avulsion is the process by which a river changes its course over time. Erosion is the process by which a river wears away its bed and banks. Transportation is the process by which sediment is carried downstream by the river. Deposition is the process by which sediment is deposited on the riverbed.

Multiple choice

Which of the following is NOT a type of river terrace?

  1. Floodplain terrace

  2. Abandoned floodplain terrace

  3. Strath terrace

  4. Pediment terrace
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Pediment terraces are not a type of river terrace. Floodplain terraces, abandoned floodplain terraces, and strath terraces are all types of river terraces.

Multiple choice

What is the term for the process by which a river forms a delta?

  1. Erosion

  2. Transportation

  3. Deposition

  4. Avulsion
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Deposition is the process by which a river forms a delta. Erosion is the process by which a river wears away its bed and banks. Transportation is the process by which sediment is carried downstream by the river. Avulsion is the process by which a river changes its course over time.

Multiple choice

What is the term for the process by which a river erodes its headwaters?

  1. Headward erosion

  2. Lateral erosion

  3. Vertical erosion

  4. Downstream erosion
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Headward erosion is the process by which a river erodes its headwaters. Lateral erosion is the process by which a river erodes its banks. Vertical erosion is the process by which a river erodes its bed. Downstream erosion is the process by which a river erodes its downstream reaches.

  1. Erosion

  2. Transportation

  3. Deposition

  4. Avulsion
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Avulsion is the process by which a river forms an oxbow lake. Erosion is the process by which a river wears away its bed and banks. Transportation is the process by which sediment is carried downstream by the river. Deposition is the process by which sediment is deposited on the riverbed.

Multiple choice

What is the term for the process by which a river erodes its bed and banks due to the force of gravity?

  1. Erosion

  2. Transportation

  3. Deposition

  4. Avulsion
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Erosion is the process by which a river erodes its bed and banks due to the force of gravity. Transportation is the process by which sediment is carried downstream by the river. Deposition is the process by which sediment is deposited on the riverbed. Avulsion is the process by which a river changes its course over time.

Multiple choice

Which type of soil erosion involves the removal of topsoil by wind?

  1. Sheet erosion

  2. Rill erosion

  3. Gully erosion

  4. Wind erosion
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Wind erosion is the process by which wind detaches and transports soil particles, primarily affecting loose and dry soils in arid and semi-arid regions.

Multiple choice

Which of the following is NOT a type of soil erosion control structure?

  1. Check dams

  2. Grassed waterways

  3. Contour bunds

  4. Windbreaks
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Windbreaks are not soil erosion control structures. They are rows of trees or shrubs planted to reduce wind speed and protect soil from wind erosion.

Multiple choice

Which of the following is an example of a fluvial process?

  1. Erosion by wind

  2. Glacial deposition

  3. Chemical weathering

  4. Stream erosion
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Fluvial processes are those associated with the movement of water, and stream erosion is the process by which water flowing in a stream erodes the land.

Multiple choice

What is the term used to describe the process by which sediment is transported by wind?

  1. Erosion

  2. Weathering

  3. Deposition

  4. Aeolian transport
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Aeolian transport is the process by which sediment is transported by wind.

Multiple choice

Which of the following is an example of a mass wasting process?

  1. Rockfall

  2. Landslide

  3. Creep

  4. Solifluction
Reveal answer Fill a bubble to check yourself
B Correct answer
Explanation

Mass wasting processes are those in which large amounts of soil and rock move downslope under the influence of gravity. Landslides are a type of mass wasting process in which a large mass of soil and rock moves downslope rapidly.
