Geomorphic Processes Questions

Multiple choice

How does sea level rise contribute to coastal erosion?

  1. It increases the erosive power of waves

  2. It inundates low-lying coastal areas

  3. It accelerates the rate of cliff retreat

  4. All of the above
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Sea level rise exacerbates coastal erosion by increasing the erosive power of waves, inundating low-lying coastal areas, and accelerating the rate of cliff retreat.

Multiple choice

Which of the following is an example of a hard engineering approach to coastal erosion management?

  1. Beach nourishment

  2. Dune restoration

  3. Seawalls

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

Seawalls are a hard engineering structure designed to protect coastal areas from erosion by reflecting wave energy.

Multiple choice

What is the term for the process by which wind erodes and transports sediment?

  1. Abrasion

  2. Attrition

  3. Deflation

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

Deflation is the process by which wind erodes and transports sediment. It occurs when the wind picks up loose sediment and carries it away.

Multiple choice

Which of the following is NOT a type of mass wasting?

  1. Landslide

  2. Mudflow

  3. Rockfall

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

Erosion is the process by which sediment is worn away and transported by wind, water, or ice. It is not a type of mass wasting, which is the movement of large amounts of sediment down a slope.

Multiple choice

What is the term for the process by which water erodes and transports sediment?

  1. Abrasion

  2. Attrition

  3. Deflation

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

Corrasion is the process by which water erodes and transports sediment. It occurs when water picks up loose sediment and carries it away.

Multiple choice

Which of the following is NOT a type of fluvial landform?

  1. Floodplain

  2. Meander

  3. Delta

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

Dunes are not fluvial landforms. They are aeolian landforms, which are formed by the wind.

Multiple choice

What is the term for the process by which glaciers erode and transport sediment?

  1. Abrasion

  2. Attrition

  3. Deflation

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

Plucking is the process by which glaciers erode and transport sediment. It occurs when glaciers freeze onto loose sediment and carry it away.

Multiple choice

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

  1. Moraine

  2. Esker

  3. Drumlin

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

Sand dunes are not glacial landforms. They are aeolian landforms, which are formed by the wind.

Multiple choice

What is the term for the process by which waves erode and transport sediment?

  1. Abrasion

  2. Attrition

  3. Deflation

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

Longshore drift is the process by which waves erode and transport sediment. It occurs when waves strike the shore at an angle and carry sediment along the coast.

Multiple choice

What is the term for the process by which groundwater dissolves and transports rock?

  1. Abrasion

  2. Attrition

  3. Deflation

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

Solution is the process by which groundwater dissolves and transports rock. It occurs when water picks up minerals from the rock and carries them away.

Multiple choice

What is the term for the process by which volcanoes erupt and deposit material on the Earth's surface?

  1. Abrasion

  2. Attrition

  3. Deflation

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

Eruption is the process by which volcanoes erupt and deposit material on the Earth's surface. It occurs when magma rises from the Earth's interior and is expelled onto the surface.

Multiple choice

What is the term for the process by which humans modify the Earth's surface?

  1. Abrasion

  2. Attrition

  3. Deflation

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

Anthropogenic modification is the process by which humans modify the Earth's surface. It occurs when humans build structures, roads, and other features that alter the landscape.

Multiple choice

Which of the following is NOT a major type of riverine depositional environment?

  1. Channel

  2. Floodplain

  3. Delta

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

Meander is a type of river bend, not a depositional environment.

Multiple choice

What is the term for the process by which sediment is transported along the bed of a river?

  1. Traction

  2. Suspension

  3. Saltation

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

Bedload is the process by which sediment is transported along the bed of a river.

Multiple choice

Which of the following factors is NOT a major control on the grain size of river sediments?

  1. Flow velocity

  2. Sediment supply

  3. Channel slope

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

Climate is not a major control on the grain size of river sediments.
