Geomorphic Processes Questions
Which of the following is an example of a fluvial process?
-
Erosion by wind
-
Glacial deposition
-
Chemical weathering
-
Stream erosion
D
Correct answer
Explanation
Fluvial processes are those associated with the movement of water, and stream erosion is the process by which water flowing in a stream erodes the land.
What is the term used to describe the process by which sediment is transported by wind?
-
Erosion
-
Weathering
-
Deposition
-
Aeolian transport
D
Correct answer
Explanation
Aeolian transport is the process by which sediment is transported by wind.
Which of the following is an example of a mass wasting process?
-
Rockfall
-
Landslide
-
Creep
-
Solifluction
B
Correct answer
Explanation
Mass wasting processes are those in which large amounts of soil and rock move downslope under the influence of gravity. Landslides are a type of mass wasting process in which a large mass of soil and rock moves downslope rapidly.
What is the term used to describe the process by which sediment is deposited by a glacier?
-
Erosion
-
Weathering
-
Deposition
-
Glacial till
D
Correct answer
Explanation
Glacial till is the term used to describe the sediment that is deposited by a glacier.
What is the term used to describe the process by which sediment is transported by waves?
-
Erosion
-
Weathering
-
Deposition
-
Longshore drift
D
Correct answer
Explanation
Longshore drift is the process by which sediment is transported by waves along the coast.
What is the term used to describe the process by which sediment is deposited by a river?
-
Erosion
-
Weathering
-
Deposition
-
Alluvial fan
D
Correct answer
Explanation
Alluvial fans are formed by the deposition of sediment by a river.
What is the term used to describe the process by which sediment is transported by ice?
-
Erosion
-
Weathering
-
Deposition
-
Glacial transport
D
Correct answer
Explanation
Glacial transport is the process by which sediment is transported by ice.
What is the term used to describe the process by which sediment is transported by gravity?
-
Erosion
-
Weathering
-
Deposition
-
Mass wasting
D
Correct answer
Explanation
Mass wasting is the process by which sediment is transported by gravity.
Which of the following is an example of a desert landform?
-
Sand dunes
-
Wadis
-
Playas
-
Salt flats
A
Correct answer
Explanation
Desert landforms are those that are found in deserts. Sand dunes are a type of desert landform that is formed by the accumulation of wind-blown sand.
What is the term used to describe the process by which sediment is transported by water?
-
Erosion
-
Weathering
-
Deposition
-
Fluvial transport
D
Correct answer
Explanation
Fluvial transport is the process by which sediment is transported by water.
What is the primary cause of river meandering?
-
Erosion of the riverbank
-
Deposition of sediment on the riverbed
-
Lateral movement of the river channel
-
Changes in the river's gradient
C
Correct answer
Explanation
River meandering is caused by the lateral movement of the river channel, which is driven by the force of the water flowing through the channel. As water flows around bends in the river, it erodes the outer bank and deposits sediment on the inner bank, causing the river to gradually change its course.
What is the term for the process by which a river splits into multiple channels that rejoin downstream?
-
Meandering
-
Braiding
-
Anabranching
-
Bifurcation
B
Correct answer
Explanation
Braiding is the process by which a river splits into multiple channels that rejoin downstream. This can occur when the river's sediment load is high, the riverbed is steep, or the river's flow is variable.
What is the primary factor that determines whether a river will meander or braid?
-
The river's gradient
-
The river's sediment load
-
The river's flow regime
-
All of the above
D
Correct answer
Explanation
The primary factor that determines whether a river will meander or braid is a combination of the river's gradient, sediment load, and flow regime. Rivers with a low gradient, high sediment load, and variable flow regime are more likely to braid, while rivers with a high gradient, low sediment load, and steady flow regime are more likely to meander.
What is the term for the process by which a river's meanders become increasingly sinuous?
-
Incision
-
Aggradation
-
Meander cutoff
-
Neck cutoff
D
Correct answer
Explanation
Neck cutoff is the process by which a river's meanders become increasingly sinuous. This occurs when the river erodes the neck of a meander, causing the meander to be cut off from the main channel. The cutoff meander then becomes an oxbow lake.
What is the term for the process by which a braided river channel becomes narrower and deeper?
-
Incision
-
Aggradation
-
Channel avulsion
-
Meander cutoff
A
Correct answer
Explanation
Incision is the process by which a braided river channel becomes narrower and deeper. This occurs when the river erodes its bed and banks, causing the channel to become entrenched. Incision can be caused by a variety of factors, including changes in the river's sediment load, flow regime, or gradient.
