Geomorphic Processes Questions
What is the process by which harmful substances are introduced into the soil?
-
Erosion
-
Leaching
-
Pollution
-
Weathering
C
Correct answer
Explanation
Pollution is the process by which harmful substances are introduced into the soil, water, or air.
What is the process by which water evaporates from the Earth's surface and condenses in the atmosphere?
-
Condensation
-
Evaporation
-
Precipitation
-
Transpiration
B
Correct answer
Explanation
Evaporation is the process by which water changes from a liquid to a gas.
What is the term used to describe the ability of soil to resist erosion by water?
-
Erodibility
-
Permeability
-
Compressibility
-
Specific gravity
A
Correct answer
Explanation
Erodibility is the property that governs the susceptibility of soil to erosion by water, which is important for assessing the stability of slopes and riverbanks.
What is the term used to describe the process of soil degradation?
-
Erosion
-
Salinization
-
Compaction
-
All of the above
D
Correct answer
Explanation
Soil degradation is the process of soil becoming less productive. It can be caused by a variety of factors, including erosion, salinization, compaction, and pollution.
-
A method for calculating beach erosion rates
-
A method for designing coastal structures
-
A method for assessing the impact of sea level rise on coastal erosion
-
All of the above
A
Correct answer
Explanation
The Bruun Rule is a method for calculating beach erosion rates based on the relationship between sea level rise and beach elevation. The rule states that for every 1 meter of sea level rise, the beach will erode by a certain amount, typically between 100 and 200 meters. The Bruun Rule is a simple but effective method for estimating beach erosion rates, and it is often used in coastal planning and management.
What is the Shoreline Change Analysis (SCA)?
-
A method for measuring beach erosion
-
A method for identifying beach hazards
-
A method for designing coastal structures
-
All of the above
A
Correct answer
Explanation
The Shoreline Change Analysis (SCA) is a method for measuring beach erosion by comparing the position of the shoreline over time. The SCA can be used to identify areas that are experiencing erosion, and it can also be used to track the rate of erosion. The SCA is a valuable tool for coastal managers, as it can help them to identify areas that are at risk of erosion and to develop strategies for protecting these areas.
What is the term used to describe the process of soil degradation caused by human activities?
-
Soil erosion
-
Soil salinization
-
Soil compaction
-
All of the above
D
Correct answer
Explanation
Soil degradation can be caused by a variety of human activities, including soil erosion, soil salinization, and soil compaction.
Which of the following is NOT a type of soil erosion?
-
Wind erosion
-
Water erosion
-
Sheet erosion
-
Rill erosion
D
Correct answer
Explanation
Rill erosion is not a type of soil erosion, but rather a type of gully erosion.
What is the name of the process by which Earth's atmosphere is gradually losing its hydrogen and helium gases?
-
Atmospheric Escape
-
Weathering
-
Erosion
-
Deposition
A
Correct answer
Explanation
Atmospheric Escape is the process by which Earth's atmosphere gradually loses its hydrogen and helium gases due to their high kinetic energy and low molecular weight.
What is the name of the mineral deposit that hangs from the ceiling of a cave?
-
Stalactite
-
Stalagmite
-
Column
-
Flowstone
A
Correct answer
Explanation
Stalactites are mineral deposits that hang from the ceiling of a cave, formed by the dripping of water containing dissolved minerals.
Which type of cave is formed by the erosion of rocks by flowing water?
-
Lava cave
-
Sea cave
-
Glacier cave
-
River cave
D
Correct answer
Explanation
River caves are formed by the erosive action of flowing water, which gradually wears away the rock and creates cave passages.
What is the term for a cave that is formed by the erosion of rocks by wind?
-
Lava cave
-
Sea cave
-
Eolian cave
-
Glacier cave
C
Correct answer
Explanation
Eolian caves are formed by the erosive action of wind, which gradually wears away the rock and creates cave passages.
What is the term for a cave that is formed by the erosion of rocks by ice?
-
Lava cave
-
Sea cave
-
Glacier cave
-
Eolian cave
C
Correct answer
Explanation
Glacier caves are formed by the erosive action of ice, which gradually wears away the rock and creates cave passages.
Which of the following is a common type of cave formation created by the erosion of rocks by waves?
-
Stalactite
-
Stalagmite
-
Column
-
Sea cave
D
Correct answer
Explanation
Sea caves are formed by the erosive action of waves, which gradually wear away the rock and create cave passages.
What is the primary agent of erosion in deserts?
A
Correct answer
Explanation
Wind is the primary agent of erosion in deserts due to the lack of vegetation and the presence of loose, sandy soils.
