Geomorphic Processes Questions

Multiple choice

Which landform is formed by the erosion of a coastline by waves and wind?

  1. Sea stack

  2. Sea cave

  3. Blowhole

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

A blowhole is a landform formed by the erosion of a coastline by waves and wind, resulting in a hole or tunnel in a rock formation through which water is forced.

Multiple choice

What is the process by which sediment is deposited by a glacier?

  1. Erosion

  2. Deposition

  3. Sedimentation

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

Deposition is the process by which sediment is deposited by a glacier, typically at its terminus or along its sides.

Multiple choice

In mountaineering, what is the term for a large accumulation of loose rocks and debris at the base of a mountain?

  1. Crevasse

  2. Moraine

  3. Talus

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

Talus is a large accumulation of loose rocks and debris at the base of a mountain, formed by the weathering and erosion of rocks.

Multiple choice

What is the name of the process by which rocks are broken down into smaller pieces by physical and chemical weathering?

  1. Erosion

  2. Weathering

  3. Deposition

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

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

Multiple choice

What is the name of the process by which sediments are transported from one location to another by wind, water, or ice?

  1. Erosion

  2. Weathering

  3. Deposition

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

Transportation is the process by which sediments are transported from one location to another by wind, water, or ice.

Multiple choice

The process by which rocks and minerals are broken down into smaller particles, creating soil, is known as:

  1. Weathering

  2. Erosion

  3. Deposition

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

Weathering is the process of breaking down rocks and minerals into smaller particles, which eventually leads to the formation of soil.

Multiple choice

Which of the following is a type of deposition?

  1. Wet deposition

  2. Dry deposition

  3. Both a and b

  4. None of the above
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Wet deposition and dry deposition are both types of deposition.

Multiple choice

What is the term used to describe the gradual deformation of rocks over time due to sustained stress?

  1. Creep

  2. Elasticity

  3. Plasticity

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

Creep is the time-dependent deformation of rocks under sustained stress, where the deformation continues even after the stress is applied.

Multiple choice

What is the term used to describe the ability of a rock to resist weathering and erosion?

  1. Durability

  2. Strength

  3. Hardness

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

Durability is the measure of a rock's resistance to weathering and erosion processes over time.

Multiple choice

What is the process by which coral reefs are formed called?

  1. Coral bleaching

  2. Coral spawning

  3. Coral recruitment

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

Coral growth is the process by which coral polyps secrete a hard exoskeleton made of calcium carbonate. Over time, these exoskeletons build up to form coral reefs.

Multiple choice

Which of the following is a common method for controlling soil erosion?

  1. Contour plowing

  2. Terracing

  3. Reforestation

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

Contour plowing, terracing, and reforestation are all common methods used to control soil erosion.

Multiple choice

What is the term for the process by which nutrients from land are carried to coastal and marine ecosystems?

  1. Eutrophication

  2. Runoff

  3. Erosion

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

Runoff is the process by which water, along with nutrients and pollutants, flows from land into coastal and marine ecosystems.

Multiple choice

The process of erosion and deposition along continental margins is influenced by:

  1. Waves

  2. Currents

  3. Wind

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

Erosion and deposition along continental margins are influenced by waves, currents, wind, and other factors.

Multiple choice

What is terracing?

  1. Building earthen embankments across a slope

  2. Building stone walls across a slope

  3. Building concrete walls across a slope

  4. Building wooden walls across a slope
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

Terracing is a method of soil conservation that involves building earthen embankments across a slope. This helps to reduce soil erosion and improve soil moisture retention.

Multiple choice

Which of the following is not a type of soil erosion?

  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 not a type of soil erosion. It is a type of land degradation.
