Geomorphic Processes Questions
The process by which water moves downward through the soil profile under the influence of gravity is known as:
-
Infiltration
-
Percolation
-
Capillary Action
-
Lateral Flow
B
Correct answer
Explanation
Percolation is the downward movement of water through the soil profile under the influence of gravity.
The process by which water moves upward through the soil profile against the force of gravity is called:
-
Infiltration
-
Percolation
-
Capillary Action
-
Lateral Flow
C
Correct answer
Explanation
Capillary action is the movement of water upward through the soil profile against the force of gravity.
The phenomenon where water moves from an area of low soil moisture content to an area of high soil moisture content is called:
-
Infiltration
-
Percolation
-
Capillary Action
-
Lateral Flow
C
Correct answer
Explanation
Capillary action is the movement of water from an area of low soil moisture content to an area of high soil moisture content.
Which of the following is a primary cause of soil erosion?
-
Wind
-
Water
-
Gravity
-
All of the above
D
Correct answer
Explanation
Soil erosion can be caused by wind, water, gravity, or a combination of these factors.
The term 'watershed' refers to:
-
An area of land that drains into a river or stream
-
A body of water surrounded by land
-
A type of soil conservation practice
-
None of the above
A
Correct answer
Explanation
A watershed is an area of land that drains into a river or stream. Watersheds are important for managing water resources and preventing soil erosion.
What is the term for a permaculture design that uses contour lines to create terraces and swales for water management?
-
Keyline design
-
Agroforestry
-
Forest garden
-
Alley cropping
A
Correct answer
Explanation
Keyline design is a permaculture design that uses contour lines to create terraces and swales for water management, reducing erosion and improving water infiltration.
Which permaculture technique involves using natural materials, such as rocks or logs, to create structures that support plants and reduce erosion?
-
Rock wall
-
Swale
-
Mulching
-
Green manuring
A
Correct answer
Explanation
A rock wall is a permaculture technique where natural materials, such as rocks or logs, are used to create structures that support plants and reduce erosion.
What is the term for the process of breaking down and weathering of rocks and minerals to form soil?
-
Erosion
-
Weathering
-
Deposition
-
Humification
B
Correct answer
Explanation
Weathering is the process by which rocks and minerals are broken down into smaller particles, creating the foundation for soil formation.
What is the term for the process of water carrying away soil particles, leading to soil erosion?
-
Leaching
-
Weathering
-
Erosion
-
Humification
C
Correct answer
Explanation
Erosion is the process by which water, wind, or other natural forces carry away soil particles, resulting in soil loss.
What is the term for the process by which soil becomes alkaline due to the accumulation of bases?
-
Salinization
-
Alkalization
-
Acidification
-
Humification
B
Correct answer
Explanation
Alkalization is the process by which soil becomes alkaline due to the accumulation of bases, often caused by poor drainage or the use of alkaline fertilizers.
What is the term for the process by which soil is formed from the weathering of parent material and the accumulation of organic matter?
-
Erosion
-
Weathering
-
Deposition
-
Pedogenesis
D
Correct answer
Explanation
Pedogenesis is the process by which soil is formed from the weathering of parent material and the accumulation of organic matter, creating distinct soil horizons.
What is the term used to describe the process by which sediment is transported by a river?
-
Erosion
-
Deposition
-
Sediment transport
-
Weathering
C
Correct answer
Explanation
Sediment transport is the process by which sediment is transported by a river. It is typically measured in tons per day (t/d).
Which of the following factors is NOT a major determinant of sediment transport?
-
River discharge
-
Sediment size
-
Sediment shape
-
Vegetation
D
Correct answer
Explanation
River discharge, sediment size, and sediment shape are all major determinants of sediment transport. Vegetation, on the other hand, is not a major determinant of sediment transport.
What is the term used to describe the process by which sediment is deposited by a river?
-
Erosion
-
Deposition
-
Sediment transport
-
Weathering
B
Correct answer
Explanation
Deposition is the process by which sediment is deposited by a river. It is typically measured in tons per day (t/d).
Which of the following factors is NOT a major determinant of deposition?
-
River discharge
-
Sediment size
-
Sediment shape
-
Channel slope
D
Correct answer
Explanation
River discharge, sediment size, and sediment shape are all major determinants of deposition. Channel slope, on the other hand, is not a major determinant of deposition.
