Geomorphic Processes Questions
The process by which rocks and minerals are broken down into smaller particles by physical forces such as temperature changes, freezing and thawing, and abrasion is known as:
-
Physical weathering
-
Chemical weathering
-
Biological weathering
-
Metamorphism
A
Correct answer
Explanation
Physical weathering is the process by which rocks and minerals are broken down into smaller particles by physical forces such as temperature changes, freezing and thawing, and abrasion.
Which of the following is NOT a type of depositional landform?
-
Delta
-
Sand dune
-
Moraine
-
Floodplain
C
Correct answer
Explanation
Moraine is a landform created by glacial deposition, while delta, sand dune, and floodplain are all depositional landforms created by the accumulation of sediment by water, wind, and river processes, respectively.
The process by which rocks and minerals are broken down into smaller particles by chemical reactions with water, oxygen, and other substances is known as:
-
Physical weathering
-
Chemical weathering
-
Biological weathering
-
Metamorphism
B
Correct answer
Explanation
Chemical weathering is the process by which rocks and minerals are broken down into smaller particles by chemical reactions with water, oxygen, and other substances.
Which of the following is NOT a type of erosional landform?
-
Canyon
-
Sand dune
-
Valley
-
Mesa
B
Correct answer
Explanation
Sand dune is a depositional landform created by the accumulation of wind-blown sand, while canyon, valley, and mesa are all erosional landforms created by the removal of material by water, wind, and other erosional processes.
Which of the following is NOT a type of landform created by fluvial processes?
-
Delta
-
Sand dune
-
Floodplain
-
Meander
B
Correct answer
Explanation
Sand dune is a landform created by the accumulation of wind-blown sand, while delta, floodplain, and meander are all landforms created by fluvial processes, which involve the movement of water and sediment in rivers and streams.
The process by which sediment is sorted and deposited according to its size and weight is known as:
-
Erosion
-
Deposition
-
Transportation
-
Sorting
D
Correct answer
Explanation
Sorting is the process by which sediment is sorted and deposited according to its size and weight, often as a result of the action of water, wind, or gravity.
Which of the following is NOT a type of landform created by glacial deposition?
-
Cirque
-
Moraine
-
Drumlin
-
Sand dune
D
Correct answer
Explanation
Sand dune is a landform created by the accumulation of wind-blown sand, while cirque, moraine, and drumlin are all landforms created by glacial deposition.
The process by which sediment is transported from one location to another by the action of water is known as:
-
Erosion
-
Deposition
-
Transportation
-
Weathering
C
Correct answer
Explanation
Transportation is the process by which sediment is moved from one location to another by the action of water, wind, ice, or gravity.
Which of the following is NOT a type of landform created by wind erosion?
-
Sand dune
-
Loess
-
Playa
-
Yardang
C
Correct answer
Explanation
Playa is a landform created by the accumulation of water in a desert basin, while sand dune, loess, and yardang are all landforms created by wind erosion.
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.
