Geomorphic Processes Questions
What is the term for the process by which soil is eroded by wind or water?
-
Erosion
-
Desertification
-
Salinization
-
Acidification
A
Correct answer
Explanation
Erosion is the process by which soil is eroded by wind or water, which can lead to a loss of soil fertility and productivity.
What is the term for the process by which soil becomes compacted and loses its structure?
-
Erosion
-
Desertification
-
Salinization
-
Compaction
D
Correct answer
Explanation
Compaction is the process by which soil becomes compacted and loses its structure, which can reduce water infiltration and root growth.
What is the term for the process by which soil loses its fertility due to the leaching of nutrients?
-
Erosion
-
Desertification
-
Salinization
-
Leaching
D
Correct answer
Explanation
Leaching is the process by which soil loses its fertility due to the leaching of nutrients, which can occur naturally or as a result of human activities such as excessive irrigation.
What is the term for the process by which soil loses its fertility due to the accumulation of heavy metals?
-
Erosion
-
Desertification
-
Salinization
-
Contamination
D
Correct answer
Explanation
Contamination is the process by which soil loses its fertility due to the accumulation of heavy metals, which can occur naturally or as a result of human activities such as mining and industrial pollution.
Which of the following is NOT a primary agent of riverine erosion?
-
Hydraulic action
-
Abrasion
-
Attrition
-
Chemical weathering
D
Correct answer
Explanation
Chemical weathering is not a primary agent of riverine erosion. It is a process that occurs over long periods of time and involves the breakdown of rocks and minerals by chemical reactions with water, oxygen, and other substances.
The process by which sediment is picked up and transported by a river is known as:
-
Erosion
-
Deposition
-
Sediment transport
-
Weathering
C
Correct answer
Explanation
Sediment transport is the process by which sediment is picked up and transported by a river. It is driven by the force of the flowing water and the size, shape, and density of the sediment particles.
Which of the following is NOT a type of riverine depositional landform?
-
Floodplain
-
Delta
-
Meander
-
Natural levee
C
Correct answer
Explanation
Meanders are sinuous bends in a river channel. They are not depositional landforms, but rather erosional features that form as a result of the lateral migration of the river channel.
The process by which sediment is deposited from a river is known as:
-
Erosion
-
Deposition
-
Sediment transport
-
Weathering
B
Correct answer
Explanation
Deposition is the process by which sediment is deposited from a river. It occurs when the velocity of the flowing water decreases, causing the sediment particles to settle out of suspension.
Which of the following is NOT a factor that influences the formation of riverine landforms?
-
Discharge
-
Slope
-
Sediment load
-
Climate
D
Correct answer
Explanation
Climate is not a direct factor that influences the formation of riverine landforms. However, it can indirectly influence these landforms by affecting the discharge, slope, and sediment load of a river.
The term 'alluvial' refers to:
-
Material deposited by a river
-
Material deposited by a glacier
-
Material deposited by wind
-
Material deposited by waves
A
Correct answer
Explanation
Alluvial refers to material deposited by a river. It is typically composed of sand, silt, and clay, and can also contain gravel and boulders.
Which of the following is NOT a type of riverine erosional landform?
-
Gorge
-
Canyon
-
Floodplain
-
Valley
C
Correct answer
Explanation
Floodplains are depositional landforms, not erosional landforms. They are formed by the deposition of sediment during floods.
The process by which a river channel migrates laterally is known as:
-
Erosion
-
Deposition
-
Lateral migration
-
Sediment transport
C
Correct answer
Explanation
Lateral migration is the process by which a river channel migrates laterally. It occurs as a result of the erosion of the river bank on one side and the deposition of sediment on the other side.
Which of the following is NOT a type of riverine landform created by erosion?
-
Gorge
-
Canyon
-
Delta
-
Valley
C
Correct answer
Explanation
Deltas are depositional landforms, not erosional landforms. They are formed by the deposition of sediment at the mouth of a river.
Which of the following is NOT a type of riverine landform created by deposition?
-
Floodplain
-
Delta
-
Gorge
-
Natural levee
C
Correct answer
Explanation
Gorges are erosional landforms, not depositional landforms. They are formed by the downcutting of a river into the bedrock.
The process by which sediment is sorted by size and shape is known as:
-
Erosion
-
Deposition
-
Sediment sorting
-
Weathering
C
Correct answer
Explanation
Sediment sorting is the process by which sediment is sorted by size and shape. It occurs as a result of the differential transport of sediment particles by the flowing water.
