Geomorphic Processes Questions
What is the term used to describe the process by which a glacier calves?
-
Glacial extent
-
Glacial mass balance
-
Glacial retreat
-
Glacial surge
Correct answer
Explanation
Glacial calving is the term used to describe the process by which a glacier calves.
What is the term used to describe the process by which a glacier crevasses?
-
Glacial extent
-
Glacial mass balance
-
Glacial retreat
-
Glacial surge
Correct answer
Explanation
Glacial crevassing is the term used to describe the process by which a glacier crevasses.
What is the term used to describe the process by which a glacier surges?
-
Glacial extent
-
Glacial mass balance
-
Glacial retreat
-
Glacial surge
D
Correct answer
Explanation
Glacial surge is the term used to describe the process by which a glacier surges.
What is the term used to describe the process by which coral reefs lose their vibrant colors and become bleached?
-
Accretion
-
Erosion
-
Submergence
-
Bleaching
D
Correct answer
Explanation
Bleaching is the process by which coral reefs lose their vibrant colors and become bleached, typically due to stress factors such as elevated water temperatures or pollution.
Which type of geotextile is commonly used for erosion control in coastal areas?
-
Woven geotextiles
-
Non-woven geotextiles
-
Knitted geotextiles
-
Composite geotextiles
B
Correct answer
Explanation
Non-woven geotextiles are commonly used in coastal erosion control due to their high permeability, allowing water to pass through while retaining soil particles.
Which material is commonly used for erosion control in riverbanks?
-
Gabions
-
Geocells
-
Sandbags
-
Turf reinforcement mats
A
Correct answer
Explanation
Gabions, which are wire mesh baskets filled with rocks or other materials, are commonly used for erosion control in riverbanks due to their ability to withstand high water flows and protect against scour.
Which type of erosion control material is often used to stabilize slopes and embankments?
-
Turf reinforcement mats
-
Geosynthetic clay liners
-
Geogrids
-
Geotextile tubes
A
Correct answer
Explanation
Turf reinforcement mats are commonly used to stabilize slopes and embankments by providing a protective layer that promotes vegetation growth and reduces erosion.
Which material is commonly used for erosion control in agricultural areas?
-
Straw wattles
-
Geotextile tubes
-
Gabions
-
Geocells
A
Correct answer
Explanation
Straw wattles are commonly used in agricultural areas for erosion control, as they help slow down water flow, trap sediment, and promote vegetation growth.
What is the process by which coral reefs are formed?
-
Erosion
-
Sedimentation
-
Photosynthesis
-
Biomineralization
D
Correct answer
Explanation
Coral reefs are formed through the process of biomineralization, where coral polyps secrete calcium carbonate to build their skeletons, which accumulate over time to form large reef structures.
What is the most effective way to prevent sedimentation from basalt quarrying?
-
Construction of sediment retention ponds
-
Implementation of erosion control measures
-
Revegetation of disturbed areas
-
All of the above
D
Correct answer
Explanation
A combination of strategies, including sediment retention ponds, erosion control measures, and revegetation, is necessary to effectively prevent sedimentation from basalt quarrying.
What is the process by which soil becomes more acidic?
-
Acidification
-
Alkalization
-
Salinization
-
Erosion
A
Correct answer
Explanation
Acidification is the process by which soil becomes more acidic, typically due to the deposition of acidic compounds from the atmosphere or the leaching of nutrients from the soil.
What is the term used to describe the process of sediment transport along coastlines?
-
Longshore Drift
-
Rip Currents
-
Beach Nourishment
-
Coastal Erosion
A
Correct answer
Explanation
Longshore drift is the process by which sediment is transported along coastlines by waves and currents, shaping beaches and barrier islands.
What is the term used to describe the process of sediment deposition at the mouth of a river?
-
Delta Formation
-
Barrier Island Formation
-
Beach Nourishment
-
Coastal Erosion
A
Correct answer
Explanation
Delta formation occurs when sediment carried by a river is deposited at its mouth, creating a fan-shaped landform.
What is the term used to describe the process of seawater intrusion into coastal aquifers?
-
Salinization
-
Desalination
-
Aquifer Recharge
-
Coastal Erosion
A
Correct answer
Explanation
Salinization refers to the process where seawater intrudes into coastal aquifers, increasing the salinity of groundwater.
What is the term used to describe the process of sediment removal from coastal areas?
-
Coastal Erosion
-
Sedimentation
-
Beach Nourishment
-
Longshore Drift
A
Correct answer
Explanation
Coastal erosion refers to the process where sediment is removed from coastal areas by waves, currents, and other natural forces.
