Geomorphic Processes Questions

Multiple choice

Which of the following is NOT a type of glacial sediment?

  1. Till

  2. Loess

  3. Outwash

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

Loess is a type of wind-blown sediment, not a glacial sediment. Till, outwash, and sandur are all types of glacial sediments.

Multiple choice

What is the term used to describe a broad, flat plain that is formed by the deposition of glacial outwash?

  1. Esker

  2. Drumlin

  3. Moraine

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

A sandur is a broad, flat plain that is formed by the deposition of glacial outwash. Eskers, drumlins, and moraines are all other types of glacial deposits.

Multiple choice

Which of the following is NOT a type of glacial process?

  1. Erosion

  2. Transportation

  3. Deposition

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

Ablation is the process by which glaciers lose mass through melting, sublimation, and calving. Erosion, transportation, and deposition are all other types of glacial processes.

Multiple choice

What is the term used to describe the process by which glaciers melt and lose mass?

  1. Erosion

  2. Transportation

  3. Deposition

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

Ablation is the process by which glaciers melt and lose mass. Erosion, transportation, and deposition are all other types of glacial processes.

Multiple choice

What is the term for the process by which a river erodes its bed and banks?

  1. Deposition

  2. Erosion

  3. Transportation

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

Erosion is the process by which a river wears away its bed and banks. Deposition is the process by which sediment is deposited on the riverbed. 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 landform created by river erosion?

  1. Floodplain

  2. Meander

  3. Oxbow lake

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

Sandbars are landforms created by river deposition, not erosion. Floodplains, meanders, and oxbow lakes are all landforms created by river erosion.

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

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.

Multiple choice

What is the term for the process by which a river forms an oxbow lake?

  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.
