Geomorphic Processes Questions
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.
The process by which water moves downward through the soil profile under the influence of gravity is known as:
-
Infiltration
-
Percolation
-
Capillary Action
-
Lateral Flow
B
Correct answer
Explanation
Percolation is the downward movement of water through the soil profile under the influence of gravity.
The process by which water moves upward through the soil profile against the force of gravity is called:
-
Infiltration
-
Percolation
-
Capillary Action
-
Lateral Flow
C
Correct answer
Explanation
Capillary action is the movement of water upward through the soil profile against the force of gravity.
The phenomenon where water moves from an area of low soil moisture content to an area of high soil moisture content is called:
-
Infiltration
-
Percolation
-
Capillary Action
-
Lateral Flow
C
Correct answer
Explanation
Capillary action is the movement of water from an area of low soil moisture content to an area of high soil moisture content.
Which of the following is a primary cause of soil erosion?
-
Wind
-
Water
-
Gravity
-
All of the above
D
Correct answer
Explanation
Soil erosion can be caused by wind, water, gravity, or a combination of these factors.
The term 'watershed' refers to:
-
An area of land that drains into a river or stream
-
A body of water surrounded by land
-
A type of soil conservation practice
-
None of the above
A
Correct answer
Explanation
A watershed is an area of land that drains into a river or stream. Watersheds are important for managing water resources and preventing soil erosion.
What is the term for a permaculture design that uses contour lines to create terraces and swales for water management?
-
Keyline design
-
Agroforestry
-
Forest garden
-
Alley cropping
A
Correct answer
Explanation
Keyline design is a permaculture design that uses contour lines to create terraces and swales for water management, reducing erosion and improving water infiltration.
Which permaculture technique involves using natural materials, such as rocks or logs, to create structures that support plants and reduce erosion?
-
Rock wall
-
Swale
-
Mulching
-
Green manuring
A
Correct answer
Explanation
A rock wall is a permaculture technique where natural materials, such as rocks or logs, are used to create structures that support plants and reduce erosion.
What is the term for the process of breaking down and weathering of rocks and minerals to form soil?
-
Erosion
-
Weathering
-
Deposition
-
Humification
B
Correct answer
Explanation
Weathering is the process by which rocks and minerals are broken down into smaller particles, creating the foundation for soil formation.
