What is the term for the loss of soil fertility due to intensive agriculture?
-
Desertification
-
Erosion
-
Salinization
-
Soil degradation
D
Correct answer
Explanation
Soil degradation is the term for the loss of soil fertility due to intensive agriculture.
What is the term used to describe the degradation of land and water resources due to human activities?
-
Land degradation
-
Desertification
-
Soil erosion
-
Water pollution
A
Correct answer
Explanation
Land degradation refers to the degradation of land and water resources due to human activities, such as deforestation, overgrazing, and unsustainable agricultural practices.
What is the term used to describe the process of permafrost melting?
-
Permafrost degradation
-
Permafrost sublimation
-
Permafrost expansion
-
Permafrost contraction
A
Correct answer
Explanation
Permafrost degradation refers to the process by which permafrost thaws and transitions from a frozen to an unfrozen state.
What is the term used to describe the process of ground freezing and thawing in permafrost regions?
-
Cryoturbation
-
Frost heave
-
Needle ice formation
-
Pingos formation
A
Correct answer
Explanation
Cryoturbation is the process of ground freezing and thawing in permafrost regions, which can lead to the formation of various features such as frost heaves, needle ice, and pingos.
What is the term used to describe the process of permafrost formation?
-
Permafrost aggradation
-
Permafrost sublimation
-
Permafrost expansion
-
Permafrost contraction
A
Correct answer
Explanation
Permafrost aggradation refers to the process by which permafrost forms and expands, typically due to a decrease in temperature or an increase in snow accumulation.
What is the term used to describe the process by which coral reefs are formed?
-
Coral Bleaching
-
Coral Spawning
-
Coral Calcification
-
Coral Fragmentation
C
Correct answer
Explanation
Coral calcification is the process by which coral polyps secrete calcium carbonate to build their skeletons, contributing to the growth and structure of coral reefs.
What is the term used to describe the phenomenon where a fluid flows smoothly over a surface?
-
Laminar flow
-
Turbulent flow
-
Boundary layer
-
Drag crisis
A
Correct answer
Explanation
Laminar flow is the term used to describe the phenomenon where a fluid flows smoothly over a surface.
What is the term used to describe the process of permafrost melting or thawing?
-
Permafrost degradation
-
Permafrost subsidence
-
Permafrost thaw
-
Permafrost collapse
C
Correct answer
Explanation
Permafrost thaw refers to the process of permafrost melting or warming, leading to changes in its physical and chemical properties.
Which of the following is a potential consequence of permafrost thaw?
-
Increased soil erosion
-
Release of ancient pathogens
-
Disruption of infrastructure
-
All of the above
D
Correct answer
Explanation
Permafrost thaw can lead to increased soil erosion, release of ancient pathogens, and disruption of infrastructure due to changes in ground stability.
How does permafrost influence the formation of unique landforms in cold regions?
-
It promotes the development of pingos and palsas.
-
It creates thermokarst landscapes.
-
It has no impact on landform formation.
-
It enhances soil erosion.
A
Correct answer
Explanation
Permafrost conditions favor the formation of unique landforms such as pingos (ice-cored hills) and palsas (peat mounds), which are characteristic features of permafrost regions.
What is the term used to describe the process of soil collapse and subsidence caused by permafrost thaw?
-
Thermokarst
-
Cryogenic subsidence
-
Permafrost collapse
-
Ground subsidence
A
Correct answer
Explanation
Thermokarst refers to the process of soil collapse and subsidence caused by permafrost thaw, resulting in the formation of unique landforms such as thaw lakes, sinkholes, and gullies.
Which of the following is a consequence of coastal erosion?
-
Loss of beaches and dunes
-
Increased flooding and storm damage
-
Salinization of freshwater sources
-
All of the above
D
Correct answer
Explanation
Coastal erosion can lead to the loss of beaches and dunes, which are natural buffers against storms and flooding. It can also result in increased flooding and storm damage, as well as the salinization of freshwater sources due to saltwater intrusion.
Which process is responsible for the formation of laterite soils?
-
Erosion
-
Leaching
-
Weathering
-
Deposition
C
Correct answer
Explanation
Laterite soils are formed through intense chemical weathering under tropical and subtropical conditions.
