Geomorphic Processes Questions
Which of these is NOT a type of river erosion?
-
Headward erosion
-
Lateral erosion
-
Vertical erosion
-
Abrasion
D
Correct answer
Explanation
Abrasion is not a type of river erosion. River erosion typically occurs through headward erosion, lateral erosion, and vertical erosion.
What is the term used to describe the process by which a river's course changes over time?
-
Avulsion
-
Meandering
-
Braiding
-
Erosion
A
Correct answer
Explanation
Avulsion is the term used to describe the process by which a river's course changes over time, typically involving the abandonment of an existing channel and the formation of a new one.
What is the term used to describe the process by which a river's sediment load is sorted and deposited?
-
Sorting
-
Transportation
-
Deposition
-
Erosion
A
Correct answer
Explanation
Sorting is the process by which a river's sediment load is sorted and deposited based on particle size and density. Finer sediments are typically transported farther downstream, while coarser sediments are deposited closer to the source.
What is the name of the technique that involves planting trees in rows to slow down wind speed and reduce soil erosion in deserts?
-
Contour plowing
-
Windbreaks
-
Terracing
-
Mulching
B
Correct answer
Explanation
Windbreaks are rows of trees or shrubs planted to slow down wind speed and reduce soil erosion in deserts. They help to trap wind-blown sand and create a more favorable microclimate for plant growth.
What is the name of the technique that involves digging shallow pits in the desert to collect rainwater?
-
Contour plowing
-
Terracing
-
Mulching
-
Zai pits
D
Correct answer
Explanation
Zai pits are shallow pits dug in the desert to collect rainwater. They are typically filled with organic matter, such as manure or compost, to help retain moisture and improve soil fertility.
What is the name of the process by which water is removed from the soil by evaporation and plant transpiration?
-
Evapotranspiration
-
Condensation
-
Precipitation
-
Infiltration
A
Correct answer
Explanation
Evapotranspiration is the process by which water is removed from the soil by evaporation and plant transpiration. This process is important for the water cycle and helps to regulate the Earth's climate.
What is the name of the process by which water is stored in the soil?
-
Infiltration
-
Evaporation
-
Condensation
-
Precipitation
A
Correct answer
Explanation
Infiltration is the process by which water is stored in the soil. This process occurs when water from the surface seeps into the soil through pores and cracks.
-
The process of soil erosion
-
The process of desertification
-
The process of deforestation
-
The process of lowering the pH of a water body
D
Correct answer
Explanation
Acidification is the process of lowering the pH of a water body, which can be caused by acid rain or other factors.
What is the primary geologic process responsible for the formation of impact craters on other planets?
-
Erosion
-
Volcanism
-
Weathering
-
Impact events
D
Correct answer
Explanation
Impact craters are formed when a meteorite, asteroid, or comet collides with the surface of a planet or moon.
What is the primary geologic process responsible for the formation of canyons on other planets?
-
Erosion
-
Volcanism
-
Weathering
-
Tectonics
A
Correct answer
Explanation
Canyons are formed by the erosion of rock by wind, water, or ice over long periods of time.
What is the primary geologic process responsible for the formation of sand dunes on other planets?
-
Erosion
-
Volcanism
-
Weathering
-
Wind
D
Correct answer
Explanation
Sand dunes are formed by the erosion and deposition of sand by wind.
What is the primary geologic process responsible for the formation of glaciers on other planets?
-
Erosion
-
Volcanism
-
Weathering
-
Cold temperatures
D
Correct answer
Explanation
Glaciers are formed when snow accumulates and compresses over time, forming a solid mass of ice.
What is the primary geologic process responsible for the formation of lakes on other planets?
-
Erosion
-
Volcanism
-
Weathering
-
Hydrologic cycle
D
Correct answer
Explanation
Lakes are formed when water accumulates in a depression on the surface of a planet.
What is the primary geologic process responsible for the formation of rivers on other planets?
-
Erosion
-
Volcanism
-
Weathering
-
Hydrologic cycle
D
Correct answer
Explanation
Rivers are formed when water flows from higher elevations to lower elevations.
What is the primary geologic process responsible for the formation of deltas on other planets?
-
Erosion
-
Volcanism
-
Weathering
-
Sedimentation
D
Correct answer
Explanation
Deltas are formed when sediment is deposited at the mouth of a river.
