Geomorphic Processes Questions
What is the term for the process by which glaciers move?
-
Calving
-
Ablation
-
Crevassing
-
Surging
D
Correct answer
Explanation
Surging is the term for the process by which glaciers move rapidly forward, often over a short period of time.
What is the term for the process by which icebergs break off from glaciers?
-
Calving
-
Ablation
-
Crevassing
-
Surging
A
Correct answer
Explanation
Calving is the term for the process by which icebergs break off from glaciers.
What is the term for the process by which glaciers melt?
-
Calving
-
Ablation
-
Crevassing
-
Surging
B
Correct answer
Explanation
Ablation is the term for the process by which glaciers melt.
What is the term for the process by which glaciers form cracks?
-
Calving
-
Ablation
-
Crevassing
-
Surging
C
Correct answer
Explanation
Crevassing is the term for the process by which glaciers form cracks.
What is the term for the process by which glaciers move slowly forward?
-
Calving
-
Ablation
-
Crevassing
-
Surging
D
Correct answer
Explanation
Surging is the term for the process by which glaciers move slowly forward.
What is the term for the process by which glaciers retreat?
-
Calving
-
Ablation
-
Crevassing
-
Retreat
D
Correct answer
Explanation
Retreat is the term for the process by which glaciers retreat.
What is the process by which water flows over land surfaces and into streams, rivers, and other water bodies called?
-
Runoff
-
Infiltration
-
Evaporation
-
Transpiration
A
Correct answer
Explanation
Runoff is the process by which water flows over land surfaces and into streams, rivers, and other water bodies. It occurs when the rate of precipitation exceeds the rate of infiltration and evapotranspiration.
What is the term used to describe the flow of water in a stream or river?
-
Runoff
-
Infiltration
-
Streamflow
-
Evaporation
C
Correct answer
Explanation
Streamflow is the term used to describe the flow of water in a stream or river. It is influenced by factors such as precipitation, runoff, and groundwater discharge.
How does runoff contribute to soil erosion?
-
By carrying away soil particles
-
By increasing soil moisture
-
By reducing soil compaction
-
By promoting plant growth
A
Correct answer
Explanation
Runoff can carry away soil particles, leading to soil erosion. This is especially true when the runoff is rapid and turbulent, as it can detach and transport soil particles more easily.
What is the term used to describe the highest level of water reached in a stream or river during a flood?
-
Flood stage
-
Bankfull stage
-
Baseflow
-
Peak discharge
A
Correct answer
Explanation
Flood stage is the term used to describe the highest level of water reached in a stream or river during a flood. It is typically defined as the level at which water begins to overflow the banks of the stream or river.
What is the term used to describe the flow of water in a stream or river during dry periods?
-
Baseflow
-
Peak discharge
-
Flood stage
-
Bankfull stage
A
Correct answer
Explanation
Baseflow is the term used to describe the flow of water in a stream or river during dry periods. It is the portion of streamflow that is derived from groundwater discharge.
How does runoff contribute to the formation of deltas?
-
By depositing sediment at the mouth of a river
-
By eroding sediment from the riverbed
-
By increasing the flow velocity of the river
-
By decreasing the water temperature of the river
A
Correct answer
Explanation
Runoff can contribute to the formation of deltas by depositing sediment at the mouth of a river. This occurs when the velocity of the river decreases as it enters a larger body of water, causing the sediment to be deposited.
What is the term used to describe the process by which water moves from the land surface to the atmosphere through evaporation and transpiration?
-
Runoff
-
Infiltration
-
Evapotranspiration
-
Condensation
C
Correct answer
Explanation
Evapotranspiration is the term used to describe the process by which water moves from the land surface to the atmosphere through evaporation and transpiration. It is a key component of the water cycle.
What is the term used to describe the process of sea ice breaking up and drifting away from the coast?
-
Ice calving
-
Ice rafting
-
Ice breakup
-
Ice retreat
C
Correct answer
Explanation
Ice breakup refers to the process of sea ice breaking up and drifting away from the coast. This typically occurs in the spring and summer months as temperatures rise and the ice begins to melt.
What is the term used to describe the process of sea ice forming and attaching to the coast?
-
Ice accretion
-
Ice rafting
-
Ice advance
-
Ice calving
A
Correct answer
Explanation
Ice accretion refers to the process of sea ice forming and attaching to the coast. This typically occurs in the fall and winter months as temperatures drop and the water begins to freeze.
