Geomorphic Processes Questions
Which of the following is NOT a type of soil erosion?
-
Wind erosion
-
Water erosion
-
Tillage erosion
-
Chemical erosion
D
Correct answer
Explanation
Chemical erosion is not a type of soil erosion. Soil erosion refers to the wearing away of soil by natural forces, such as wind and water.
What is the term for the process by which soil is formed from parent material?
-
Weathering
-
Erosion
-
Deposition
-
Soil formation
D
Correct answer
Explanation
Soil formation is the process by which soil is formed from parent material, such as rock or sediment, through the action of weathering, erosion, and deposition.
-
The process by which soil is worn away by water, wind, or other natural forces.
-
The process by which soil is deposited in new locations.
-
The process by which soil is formed from rocks and minerals.
-
The process by which soil is compacted and hardened.
A
Correct answer
Explanation
Soil erosion is the process by which soil is worn away by water, wind, or other natural forces. This can happen naturally, but it can also be accelerated by human activities, such as deforestation, overgrazing, and poor farming practices.
What are the main causes of soil erosion?
-
Water
-
Wind
-
Gravity
-
All of the above
D
Correct answer
Explanation
Soil erosion can be caused by water, wind, gravity, or a combination of these factors. Water erosion is the most common type of soil erosion, and it occurs when water flows over the land and carries soil particles away. Wind erosion occurs when strong winds blow across the land and carry soil particles away. Gravity erosion occurs when soil particles are moved downhill by gravity.
What is the process by which atoms are removed from a solid surface by the impact of energetic particles called?
-
Sputtering
-
Deposition
-
Etching
-
Erosion
A
Correct answer
Explanation
Sputtering is the process by which atoms are removed from a solid surface by the impact of energetic particles.
What is the main factor that determines the rate of erosion?
-
The ion energy
-
The ion flux
-
The material surface temperature
-
The angle of incidence of the ions
D
Correct answer
Explanation
The main factor that determines the rate of erosion is the angle of incidence of the ions.
The process of soil formation from parent material is known as:
-
Weathering
-
Erosion
-
Deposition
-
Leaching
A
Correct answer
Explanation
Weathering is the process of breaking down and altering the parent material into smaller particles and minerals, which eventually form soil.
The process of water moving through the soil profile and carrying dissolved minerals and nutrients is called:
-
Leaching
-
Percolation
-
Evaporation
-
Transpiration
A
Correct answer
Explanation
Leaching is the process of water moving through the soil profile and carrying dissolved minerals and nutrients, which can result in the loss of essential elements from the soil.
The process of soil erosion by wind is known as:
-
Wind erosion
-
Water erosion
-
Rill erosion
-
Gully erosion
A
Correct answer
Explanation
Wind erosion is the process of soil erosion caused by the action of wind, which can transport soil particles and cause significant land degradation.
The process of soil erosion by water is known as:
-
Water erosion
-
Wind erosion
-
Rill erosion
-
Gully erosion
A
Correct answer
Explanation
Water erosion is the process of soil erosion caused by the action of water, which can transport soil particles and cause significant land degradation.
What is the term used to describe the process of water moving through the soil profile under the influence of gravity?
-
Infiltration
-
Evapotranspiration
-
Runoff
-
Percolation
D
Correct answer
Explanation
Percolation refers to the downward movement of water through the soil profile under the influence of gravity, contributing to groundwater recharge.
What is the term used to describe the process by which soil becomes more acidic due to climate change?
-
Soil acidification
-
Soil alkalization
-
Soil salinization
-
Soil erosion
A
Correct answer
Explanation
Soil acidification is the process by which soil becomes more acidic, typically due to increased levels of carbon dioxide in the atmosphere. Climate change can accelerate soil acidification by increasing the concentration of carbon dioxide in the air, which is absorbed by soil and forms carbonic acid.
What is the term for the process by which sea levels rise due to the melting of glaciers and ice sheets?
-
Deglaciation
-
Glaciation
-
Eustatic sea level rise
-
Isostatic sea level rise
C
Correct answer
Explanation
Eustatic sea level rise refers to the global rise in sea levels due to the addition of water from melting glaciers and ice sheets.
What is the term for the process by which sea levels rise due to the addition of water from melting glaciers and ice sheets?
-
Eustatic sea level rise
-
Isostatic sea level rise
-
Glacio-isostatic rebound
-
Thermal expansion
A
Correct answer
Explanation
Eustatic sea level rise refers to the global rise in sea levels due to the addition of water from melting glaciers and ice sheets.
What is the term used to describe the process of deterioration of cultural heritage materials due to air pollution?
-
Weathering
-
Erosion
-
Soiling
-
Air pollution damage
D
Correct answer
Explanation
Air pollution damage refers specifically to the deterioration of cultural heritage materials caused by air pollutants.
