Geomorphic Processes Questions

Multiple choice

What is the term used to describe the process by which sediment is eroded by a river?

  1. Erosion

  2. Deposition

  3. Sediment transport

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

Erosion is the process by which sediment is eroded by a river. It is typically measured in tons per day (t/d).

Multiple choice

Which of the following factors is NOT a major determinant of erosion?

  1. River discharge

  2. Sediment size

  3. Sediment shape

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

River discharge, sediment size, and sediment shape are all major determinants of erosion. Vegetation, on the other hand, is not a major determinant of erosion.

Multiple choice

What is the process by which waves bend as they approach a shoreline?

  1. Wave refraction

  2. Wave diffraction

  3. Wave interference

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

Wave refraction is the process by which waves bend as they approach a shoreline due to changes in water depth.

Multiple choice

What is the term used to describe the process of soil degradation caused by the accumulation of salts?

  1. Erosion

  2. Desertification

  3. Salinization

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

Salinization is the process of soil degradation caused by the accumulation of salts, often due to poor irrigation practices or natural factors.

Multiple choice

What is the term used to describe the process of soil degradation caused by the removal of vegetation?

  1. Erosion

  2. Desertification

  3. Salinization

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

Erosion is the process of soil degradation caused by the removal of vegetation, which exposes the soil to wind and water erosion.

Multiple choice

What is the term used to describe the process of soil degradation caused by the accumulation of acids?

  1. Erosion

  2. Desertification

  3. Salinization

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

Acidification is the process of soil degradation caused by the accumulation of acids, often due to acid rain or the use of certain fertilizers.

Multiple choice

What is the term used to describe the process of soil degradation caused by desertification?

  1. Erosion

  2. Desertification

  3. Salinization

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

Desertification is the process of soil degradation caused by the loss of vegetation and the expansion of desert-like conditions.

Multiple choice

What is the term used to describe the process of soil degradation caused by the accumulation of heavy metals?

  1. Erosion

  2. Desertification

  3. Salinization

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

Acidification is the process of soil degradation caused by the accumulation of acids, often due to acid rain or the use of certain fertilizers.

Multiple choice

Which of the following is NOT a measure to control soil erosion in the Himalayan region?

  1. Contour plowing

  2. Terracing

  3. Afforestation

  4. Slash-and-burn agriculture
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Slash-and-burn agriculture is a destructive practice that contributes to soil erosion. Contour plowing, terracing, and afforestation are all soil conservation techniques that help reduce erosion in the Himalayan region.

Multiple choice

  1. Contour plowing

  2. Terracing

  3. Afforestation

  4. Slash-and-burn agriculture
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Slash-and-burn agriculture is a destructive practice that contributes to soil erosion. Contour plowing, terracing, and afforestation are all soil conservation techniques that help reduce erosion in the Himalayan region.

Multiple choice

Which of the following is not a type of soil erosion mentioned in the Soil Conservation Act, 1970?

  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 mentioned in the Soil Conservation Act, 1970.

Multiple choice

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

  1. Ablation

  2. Accumulation

  3. Crevasses

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

Erosion is the process by which glaciers erode and transport material through the movement of ice and the grinding action of rocks and debris.

Multiple choice

What is the term for the accumulation of snow and ice on a glacier's surface?

  1. Ablation

  2. Accumulation

  3. Crevasses

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

Accumulation is the process by which snow and ice accumulate on a glacier's surface.

Multiple choice

What is the term for the deep cracks that form in a glacier's surface?

  1. Ablation

  2. Accumulation

  3. Crevasses

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

Crevasses are deep cracks that form in a glacier's surface due to the movement of ice.

Multiple choice
