  3. Weathering

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

Deposition is the process by which sediment is deposited in the sea.

Multiple choice

What is the term for the process by which rocks and sediments are eroded and transported by glaciers?

  1. Glacial erosion

  2. Glacial deposition

  3. Glacial till

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

Glacial erosion is the process by which glaciers erode and transport rocks and sediments. Glacial deposition is the process by which glaciers deposit these materials. Glacial till is a type of sediment deposited by glaciers. Periglacial processes are processes that occur in areas adjacent to glaciers.

Multiple choice

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

  1. Wind erosion

  2. Wind deposition

  3. Loess

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

Wind erosion is the process by which rocks and sediments are weathered and eroded by wind. Wind deposition is the process by which wind deposits these materials. Loess is a type of sediment deposited by wind. Desert pavement is a layer of small stones and gravel that forms on the surface of deserts.

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

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

  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.
