Geomorphic Processes Questions

Multiple choice

What is the process by which calcium carbonate dissolves in seawater called?

  1. Dissolution

  2. Erosion

  3. Weathering

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

Dissolution is the process by which calcium carbonate dissolves in seawater.

Multiple choice

What is the term used to describe the process of soil degradation in arid and semi-arid regions?

  1. Erosion

  2. Desertification

  3. Salinization

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

Desertification refers to the process of land degradation in arid and semi-arid regions, leading to the loss of vegetation and soil fertility. It is often caused by a combination of factors, including climate change, overgrazing, and unsustainable land use practices.

Multiple choice

What is the term used to describe the process of reducing the amount of salt in soil and water?

  1. Desalination

  2. Salinization

  3. Alkalization

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

Desalination refers to the process of removing salt from soil and water. It is a common practice in desert regions to improve soil fertility and make water suitable for irrigation and drinking.

Multiple choice

What is the process of removing sediment from a fossil called?

  1. Excavation

  2. Preparation

  3. Restoration

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

Preparation is the process of removing sediment from a fossil.

Multiple choice

What is the term used to describe the solids that remain suspended in water and do not settle out?

  1. Dissolved Solids

  2. Suspended Solids

  3. Colloidal Solids

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

Suspended solids are the solids that remain suspended in water due to their small size and density, preventing them from settling out.

Multiple choice

What is the primary mechanism for the formation of lakes?

  1. Glacial Erosion

  2. Volcanic Activity

  3. Tectonic Activity

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

Glacial erosion, caused by the movement of glaciers, is the primary mechanism for the formation of many lakes. As glaciers carve out depressions in the Earth's surface, these depressions can fill with water and form lakes.

Multiple choice

What is the process by which lakes gradually fill up with sediment and organic matter?

  1. Eutrophication

  2. Oligotrophication

  3. Desertification

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

Eutrophication is the process by which lakes gradually fill up with sediment and organic matter, leading to a decrease in water quality and a shift in the ecosystem.

Multiple choice

What are some of the major geochemical processes that shape the Earth's surface?

  1. Weathering, erosion, and deposition

  2. Volcanism, earthquakes, and tsunamis

  3. Plate tectonics, mountain building, and continental drift

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

All of the above processes are major geochemical processes that shape the Earth's surface.

Multiple choice

What is the process of soil formation called?

  1. Pedogenesis

  2. Erosion

  3. Weathering

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

Pedogenesis is the process of soil formation. It involves the physical, chemical, and biological processes that transform parent material into soil.

Multiple choice

What is the term used to describe the rate at which air pollutants are deposited on the ground or water?

  1. Deposition velocity

  2. Diffusion coefficient

  3. Advection rate

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

Deposition velocity is the rate at which air pollutants are deposited on the ground or water.

Multiple choice

What is the process by which weathered material is transported from one location to another?

  1. Erosion

  2. Deposition

  3. Weathering

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

Erosion is the process by which weathered material is transported from one location to another by wind, water, ice, or gravity.

Multiple choice

What is the term used to describe the process by which sediment is deposited in a new location?

  1. Erosion

  2. Deposition

  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 a new location after being transported by wind, water, ice, or gravity.

Multiple choice

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

  1. Landslides

  2. Mudflows

  3. Creep

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

Erosion is not a type of mass wasting, but rather a process that involves the transportation of weathered material.

Multiple choice

  1. Erosion

  2. Deposition

  3. Weathering

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

Weathering is the process by which rocks are broken down into smaller pieces by physical, chemical, and biological agents.
