Geomorphic Processes Questions

Multiple choice

What is the term for the process by which rocks and sediments are weathered and eroded by water?

  1. Water erosion

  2. Water deposition

  3. Alluvium

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

Water erosion is the process by which rocks and sediments are weathered and eroded by water. Water deposition is the process by which water deposits these materials. Alluvium is a type of sediment deposited by water. Floodplain is a low-lying area adjacent to a river that is subject to flooding.

Multiple choice

What is the term for the process by which rocks and sediments are weathered and eroded by chemical reactions?

  1. Chemical weathering

  2. Chemical deposition

  3. Laterite

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

Chemical weathering is the process by which rocks and sediments are weathered and eroded by chemical reactions. Chemical deposition is the process by which these materials are deposited. Laterite is a type of soil that forms in tropical regions as a result of chemical weathering. Karst topography is a landscape that is characterized by sinkholes, caves, and underground drainage systems, formed by the chemical weathering of limestone and other soluble rocks.

Multiple choice

Which of the following is a common landform found in areas of karst topography?

  1. Sinkholes

  2. Caves

  3. Uvalas

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

Sinkholes, caves, and uvalas are all common landforms found in areas of karst topography. Sinkholes are depressions in the land surface that form when the roof of a cave collapses. Caves are underground passages that are formed by the chemical weathering of limestone and other soluble rocks. Uvalas are large, closed depressions that are formed by the coalescence of multiple sinkholes.

Multiple choice

What is the term for the process by which rocks and sediments are weathered and eroded by biological activity?

  1. Biological weathering

  2. Biological deposition

  3. Bioturbation

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

Biological weathering is the process by which rocks and sediments are weathered and eroded by biological activity. Biological deposition is the process by which these materials are deposited. Bioturbation is the mixing of soil and sediment by organisms. Pedogenesis is the process of soil formation.

Multiple choice

What is the term for the process by which rocks and sediments are weathered and eroded by the combined action of physical, chemical, and biological processes?

  1. Weathering

  2. Erosion

  3. Denudation

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

Weathering is the process by which rocks and sediments are broken down into smaller pieces. Erosion is the process by which these materials are transported from one place to another. Denudation is the process by which the Earth's surface is lowered by weathering and erosion. All of these processes are interrelated and work together to shape the Earth's surface.

Multiple choice

How does sea-level rise contribute to coastal erosion?

  1. By increasing the frequency and intensity of storms

  2. By inundating coastal land

  3. By increasing 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 contributes to coastal erosion by increasing the frequency and intensity of storms, inundating coastal land, and increasing the rate of cliff retreat.

Multiple choice

What is the process by which soil is formed?

  1. Weathering of rocks

  2. Deposition of sediments

  3. Activity of living organisms

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

Soil is formed through a combination of weathering of rocks, deposition of sediments, and activity of living organisms.

Multiple choice

What is the process by which soil is eroded?

  1. Wind erosion

  2. Water erosion

  3. Tillage erosion

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

Soil erosion can be caused by wind, water, tillage, and other factors.
