Geomorphic Processes Questions
The phenomenon where waves bounce back from a surface, such as a beach or a cliff, is known as:
-
Wave interference
-
Wave diffraction
-
Wave reflection
-
Wave refraction
C
Correct answer
Explanation
Wave reflection is the phenomenon where waves bounce back from a surface, such as a beach or a cliff.
The primary mechanism by which geosynthetics filter sediment is through:
-
Adhesion
-
Friction
-
Cohesion
-
Straining
D
Correct answer
Explanation
Geosynthetics filter sediment primarily through straining, which is the physical separation of particles based on size.
The primary mechanism by which geosynthetics separate different materials is through:
-
Adhesion
-
Friction
-
Cohesion
-
Physical barrier
D
Correct answer
Explanation
Geosynthetics separate different materials primarily by acting as a physical barrier between them.
Which river channel pattern is characterized by multiple, interconnected channels separated by sediment bars?
-
Braided
-
Straight
-
Meandering
-
Anabranching
A
Correct answer
Explanation
Braided river channels are typically found in areas with high sediment loads and high flow velocities.
Which factor is primarily responsible for the formation of braided river channels?
-
High sediment load
-
Low sediment load
-
High flow velocity
-
Low flow velocity
A
Correct answer
Explanation
High sediment loads lead to the formation of sediment bars, which divide the river channel into multiple, interconnected channels.
Which factor is primarily responsible for the formation of straight river channels?
-
High sediment load
-
Low sediment load
-
High flow velocity
-
Low flow velocity
B
Correct answer
Explanation
Low sediment loads allow the river to flow in a single, straight channel without the formation of sediment bars.
Which factor is primarily responsible for the formation of meandering river channels?
-
High sediment load
-
Low sediment load
-
High flow velocity
-
Low flow velocity
Correct answer
Explanation
Moderate sediment loads allow the river to form point bars and meander bends, while still maintaining a single, sinuous channel.
Which factor is primarily responsible for the formation of anabranching river channels?
-
High sediment load
-
Low sediment load
-
High flow velocity
-
Low flow velocity
Correct answer
Explanation
High sediment loads and low flow velocities allow the river to form sediment bars and multiple, interconnected channels.
Which river channel pattern is most likely to change over time?
-
Braided
-
Straight
-
Meandering
-
Anabranching
C
Correct answer
Explanation
Meandering river channels are more likely to change over time due to the erosion and deposition of sediment, which can lead to the formation of new bends and point bars.
Which river channel pattern is most likely to be stable over time?
-
Braided
-
Straight
-
Meandering
-
Anabranching
B
Correct answer
Explanation
Straight river channels are more likely to be stable over time due to the lack of sediment bars and point bars, which can lead to changes in the channel's course.
Which river channel pattern is most likely to be found in areas with a high rate of sediment deposition?
-
Braided
-
Straight
-
Meandering
-
Anabranching
A
Correct answer
Explanation
Braided river channels are more likely to be found in areas with a high rate of sediment deposition due to the formation of sediment bars, which divide the river channel into multiple, interconnected channels.
Which river channel pattern is most likely to be found in areas with a low rate of sediment deposition?
-
Braided
-
Straight
-
Meandering
-
Anabranching
B
Correct answer
Explanation
Straight river channels are more likely to be found in areas with a low rate of sediment deposition due to the lack of sediment bars, which can lead to changes in the channel's course.
Which river channel pattern is most likely to be found in areas with a high rate of erosion?
-
Braided
-
Straight
-
Meandering
-
Anabranching
C
Correct answer
Explanation
Meandering river channels are more likely to be found in areas with a high rate of erosion due to the formation of point bars and meander bends, which can lead to the erosion of the river banks.
What is the term used to describe the movement of a glacier?
-
Ablation

D
Correct answer
Explanation
Flow is the term used to describe the movement of a glacier.
What is the term used to describe the process by which a glacier loses mass?
-
Ablation
-
Calving
-
Crevassing
-
Flow
A
Correct answer
Explanation
Ablation is the term used to describe the process by which a glacier loses mass.
