Geomorphic Processes Questions
Which of the following is NOT a type of soil erosion?
-
Sheet erosion
-
Rill erosion
-
Gully erosion
-
Wind erosion
C
Correct answer
Explanation
Gully erosion is a type of soil erosion caused by the action of water, while sheet, rill, and wind erosion are all caused by the action of wind.
What is the term for the process by which soil is eroded by wind or water?
-
Erosion
-
Weathering
-
Deposition
-
Landslide
-
Subsidence
A
Correct answer
Explanation
Erosion is the process by which soil is worn away by the action of wind or water.
What is the term used to describe the phenomenon of melting permafrost due to rising global temperatures?
-
Desertification
-
Thaw
-
Deforestation
-
Acidification
B
Correct answer
Explanation
Thaw refers to the melting of permafrost due to increasing temperatures, leading to various environmental consequences.
What is the primary cause of the formation of the Gangetic Plain?
-
Glacial deposition
-
River deposition
-
Wind deposition
-
Volcanic activity
B
Correct answer
Explanation
The Gangetic Plain was formed by the deposition of sediments by the Ganges River and its tributaries.
Which coastal process is responsible for the formation of barrier islands?
-
Longshore drift
-
Wave refraction
-
Beach nourishment
-
Seawall construction
A
Correct answer
Explanation
Barrier islands are formed by the process of longshore drift, where sediment is transported along the coast by waves and currents, and deposited in shallow waters, creating elongated, narrow islands parallel to the shoreline.
What is the term used to describe the gradual wearing away of coastal landforms by wave action and other erosive forces?
-
Coastal erosion
-
Beach accretion
-
Sea level rise
-
Saltwater intrusion
A
Correct answer
Explanation
Coastal erosion is the process by which coastal landforms, such as beaches, cliffs, and dunes, are gradually worn away by wave action, tidal currents, and other erosive forces.
What is the term used to describe the process of artificially adding sand to a beach to combat erosion?
-
Beach nourishment
-
Seawall construction
-
Dune restoration
-
Breakwater installation
A
Correct answer
Explanation
Beach nourishment is the process of adding sand to a beach to combat erosion and restore its natural profile. It involves transporting sand from offshore or other sources and placing it on the eroding beach.
What is the term used to describe the process by which waves break at an angle to the shoreline, causing sediment to be transported along the coast?
-
Longshore drift
-
Wave refraction
-
Rip current formation
-
Beach cusps development
A
Correct answer
Explanation
Longshore drift is the process by which waves break at an angle to the shoreline, causing sediment to be transported along the coast in the direction of the wave's approach.
Which coastal process is responsible for the formation of salt marshes?
-
Tidal inundation
-
Wave erosion
-
Longshore drift
-
Beach nourishment
A
Correct answer
Explanation
Salt marshes are formed through the process of tidal inundation, where regular flooding by tides deposits sediment and promotes the growth of salt-tolerant vegetation, such as cordgrass.
What is the term used to describe the process by which sediment is transported away from a beach by waves and currents?
-
Beach erosion
-
Longshore drift
-
Rip current formation
-
Offshore sediment transport
D
Correct answer
Explanation
Offshore sediment transport is the process by which sediment is transported away from a beach by waves and currents, typically to deeper waters.
What is the term used to describe the process by which waves break and dissipate their energy before reaching the shoreline?
-
Wave refraction
-
Wave reflection
-
Wave diffraction
-
Wave breaking
D
Correct answer
Explanation
Wave breaking is the process by which waves break and dissipate their energy before reaching the shoreline, typically due to interactions with the seabed or changes in water depth.
What is the term used to describe the process by which waves change direction as they approach the shoreline due to variations in water depth?
-
Wave refraction
-
Wave reflection
-
Wave diffraction
-
Wave breaking
A
Correct answer
Explanation
Wave refraction is the process by which waves change direction as they approach the shoreline due to variations in water depth, causing them to bend towards shallower water.
Which cave management technique involves closing a cave to all visitors for a period of time to allow it to recover from human impact?
-
Cave closure
-
Visitation permits
-
Guided tours
-
Zoning
A
Correct answer
Explanation
Cave closure is a cave management technique that involves closing a cave to all visitors for a period of time to allow it to recover from human impact, such as excessive visitation or vandalism.
The process by which water moves from the soil surface to the atmosphere through evaporation and transpiration is known as:
-
Infiltration
-
Percolation
-
Evapotranspiration
-
Desiccation
C
Correct answer
Explanation
Evapotranspiration is the combined process of evaporation from the soil surface and transpiration from plants.
The phenomenon where water moves from an area of high soil moisture content to an area of low soil moisture content is called:
-
Infiltration
-
Percolation
-
Capillary Action
-
Lateral Flow
D
Correct answer
Explanation
Lateral flow is the movement of water within the soil from areas of high moisture content to areas of low moisture content.
