Geomorphic Processes Questions
How can beach nourishment help address coastal erosion?
-
It replenishes sand on eroded beaches
-
It protects coastal infrastructure
-
It improves water quality
-
All of the above
D
Correct answer
Explanation
Beach nourishment involves replenishing sand on eroded beaches, protecting coastal infrastructure, and improving water quality.
The process of soil formation from parent material is known as:
-
Weathering
-
Erosion
-
Deposition
-
Humification
A
Correct answer
Explanation
Weathering is the process by which rocks and minerals are broken down into smaller particles, creating the parent material for soil formation.
What is the term for the layer of soil that is formed by the accumulation of weathered rock fragments?
-
O Horizon
-
A Horizon
-
B Horizon
-
C Horizon
D
Correct answer
Explanation
The C Horizon, also known as the subsoil, is the layer of soil that is formed by the accumulation of weathered rock fragments and is located beneath the A and B horizons.
What is the process by which coral reefs are formed?
-
Erosion
-
Volcanic activity
-
Coral growth
-
Weathering
C
Correct answer
Explanation
Coral reefs are formed through the growth and accumulation of coral skeletons, which are deposited on top of each other over time, creating complex and diverse underwater ecosystems.
What is the term for the process by which coral reefs are formed?
-
Corallization
-
Biomineralization
-
Calcification
-
Reef accretion
D
Correct answer
Explanation
Reef accretion is the process by which coral reefs are formed. It involves the accumulation of calcium carbonate skeletons secreted by coral polyps, along with other materials such as sediment and algae, over time.
Which of the following is NOT a common type of soil erosion caused by Indian temples?
-
Water erosion
-
Wind erosion
-
Gully erosion
-
All of the above
D
Correct answer
Explanation
All of the above are types of soil erosion caused by Indian temples.
Which of the following is NOT a common type of soil erosion caused by Indian temples?
-
Water erosion
-
Wind erosion
-
Gully erosion
-
All of the above
D
Correct answer
Explanation
All of the above are types of soil erosion caused by Indian temples.
What is the term for the removal of overburden, or waste rock, to expose the desired mineral deposit?
-
Stripping
-
Excavation
-
Quarrying
-
Drilling
A
Correct answer
Explanation
Stripping is the process of removing overburden, or waste rock, to expose the desired mineral deposit.
What is the process by which rising sea levels cause coastal erosion?
-
Wave action
-
Tidal currents
-
Storm surges
-
All of the above
D
Correct answer
Explanation
Rising sea levels can cause coastal erosion through various processes, including wave action, tidal currents, and storm surges. These processes erode coastal landforms, leading to the loss of beaches, cliffs, and other coastal habitats.
What is the term used to describe the construction of structures to protect coastal areas from rising sea levels and coastal erosion?
-
Coastal adaptation
-
Coastal defense
-
Coastal hardening
-
Coastal resilience
B
Correct answer
Explanation
Coastal defense refers to the construction of structures, such as seawalls, breakwaters, and levees, to protect coastal areas from rising sea levels and coastal erosion.
What is the term used to describe the process by which coastal areas are gradually submerged by rising sea levels?
-
Coastal inundation
-
Coastal flooding
-
Coastal submergence
-
Coastal retreat
A
Correct answer
Explanation
Coastal inundation refers to the process by which coastal areas are gradually submerged by rising sea levels, resulting in the loss of land and infrastructure.
How does contour bunding help to reduce soil erosion?
-
By slowing down the flow of water
-
By trapping sediment
-
By increasing infiltration
-
All of the above
D
Correct answer
Explanation
Contour bunding helps to reduce soil erosion by slowing down the flow of water, trapping sediment, and increasing infiltration.
What is the primary agent responsible for riverbank erosion?
C
Correct answer
Explanation
Riverbank erosion is primarily caused by the erosive action of flowing water, which can wear away the soil and sediment along the riverbanks.
Which of the following factors can contribute to increased riverbank erosion?
-
Vegetation cover
-
Steep riverbanks
-
High water velocity
-
Stable riverbed
B
Correct answer
Explanation
Steep riverbanks are more susceptible to erosion as they are less able to resist the erosive forces of flowing water.
What is the term used to describe the process of sediment deposition along the banks of a river?
-
Erosion
-
Sedimentation
-
Transportation
-
Deposition
B
Correct answer
Explanation
Sedimentation refers to the process by which sediment is deposited along the banks of a river, typically in areas where the water velocity decreases.
