Geomorphic Processes Questions
Which of the following is an example of a soft engineering technique for coastal erosion management?
-
Artificial reefs
-
Beach nourishment
-
Seawalls
-
Dune restoration
D
Correct answer
Explanation
Dune restoration is an example of a soft engineering technique for coastal erosion management, as it involves restoring natural dunes, which provide protection against erosion.
Which of the following is an example of a non-structural measure for coastal erosion management?
-
Artificial reefs
-
Beach nourishment
-
Seawalls
-
Zoning regulations
D
Correct answer
Explanation
Zoning regulations are an example of a non-structural measure for coastal erosion management, as they restrict development in areas that are vulnerable to erosion.
What is the term for the process by which nutrients are lost from the soil?
-
Leaching
-
Erosion
-
Volatilization
-
All of the above
D
Correct answer
Explanation
Nutrients can be lost from the soil through leaching, erosion, and volatilization, all of which can lead to nutrient deficiencies in plants.
What is the term used to describe the study of the movement and distribution of water on, above, and below the Earth's surface?
-
Hydrology
-
Geology
-
Meteorology
-
Ecology
A
Correct answer
Explanation
Hydrology is the branch of science that deals with the properties, distribution, and movement of water.
Which of the following is a type of dry deposition?
-
Gravitational settling
-
Impaction
-
Diffusion
-
All of the above
D
Correct answer
Explanation
Dry deposition can occur through gravitational settling, impaction, and diffusion. Gravitational settling is the process by which particles fall to the ground due to gravity. Impaction is the process by which particles collide with surfaces and stick to them. Diffusion is the process by which particles move from areas of high concentration to areas of low concentration.
Which geosynthetic material is commonly used for erosion control applications?
-
Geotextiles
-
Geogrids
-
Geomembranes
-
Turf Reinforcement Mats (TRMs)
A
Correct answer
Explanation
Geotextiles are commonly used for erosion control applications due to their ability to protect soil surfaces from wind and water damage.
What is the term used to describe the process of melting and refreezing of permafrost, which can occur due to climate change or mining activities?
-
Cryoturbation
-
Thermokarst
-
Pingos
-
Solifluction
B
Correct answer
Explanation
Thermokarst is the process of melting and refreezing of permafrost, resulting in the formation of various landforms such as sinkholes, lakes, and gullies.
What is the term for the study of the movement of water through the Earth's subsurface?
-
Hydrogeology
-
Hydrology
-
Hydrodynamics
-
Hydrometeorology
A
Correct answer
Explanation
Hydrogeology is the branch of hydrology that deals with the movement of water through the Earth's subsurface, including groundwater flow and aquifer recharge.
What is the term for the study of the movement of water on the Earth's surface?
-
Hydrogeology
-
Hydrology
-
Hydrodynamics
-
Hydrometeorology
B
Correct answer
Explanation
Hydrology is the branch of science that deals with the movement of water on the Earth's surface, including rivers, lakes, and oceans.
What is the process by which coral reefs are formed?
-
Erosion
-
Deposition
-
Accretion
-
Calcification
D
Correct answer
Explanation
Coral reefs are formed through the process of calcification, where tiny marine organisms called coral polyps secrete calcium carbonate to build their skeletons. Over time, these skeletons accumulate, forming massive coral structures.
What is the term used to describe the process of soil formation?
-
Weathering
-
Erosion
-
Deposition
-
Pedogenesis
D
Correct answer
Explanation
Pedogenesis is the term used to describe the process of soil formation. It involves the physical, chemical, and biological processes that transform parent material into soil.
What is the term used to describe the process of soil degradation?
-
Weathering
-
Erosion
-
Deposition
-
Desertification
D
Correct answer
Explanation
Desertification is the term used to describe the process of soil degradation, particularly in arid and semi-arid regions. It involves the loss of soil fertility and the transformation of productive land into desert-like conditions.
How does soil erosion affect soil structure?
-
It removes the fertile topsoil.
-
It exposes the subsoil, which is less fertile.
-
It reduces soil organic matter content.
-
All of the above
D
Correct answer
Explanation
Soil erosion affects soil structure by removing the fertile topsoil, exposing the subsoil which is less fertile, and reducing soil organic matter content.
What is the role of terraces in soil conservation?
-
They reduce the slope length.
-
They slow down the flow of water.
-
They prevent soil erosion.
-
All of the above
D
Correct answer
Explanation
Terraces play a crucial role in soil conservation by reducing the slope length, slowing down the flow of water, and preventing soil erosion.
What is the term used to describe the process by which marine debris breaks down into smaller pieces?
-
Fragmentation
-
Degradation
-
Weathering
-
Erosion
A
Correct answer
Explanation
Fragmentation refers to the process by which marine debris breaks down into smaller pieces due to physical, chemical, and biological factors.
