erosion trivia questions
Erosion is the movement of soil or rock by agents such as water, wind, ice, and what?
Answer: Gravity
Bonus fact: Erosion transports weathered material from one place to another.
What process is different from erosion because it breaks rock down in place rather than transporting it?
Answer: Weathering
Bonus fact: Weathering breaks rock apart or alters it chemically; erosion moves the resulting material.
What type of erosion occurs when a river cuts downward into its bed, deepening a valley?
Answer: Vertical erosion
Bonus fact: Vertical erosion is especially important in the upper courses of rivers.
Erosion control aims to keep what from being carried away?
Answer: Soil
Bonus fact: Wind and water can remove exposed soil.
Planting vegetation helps control erosion because roots do what?
Answer: Hold soil in place
Bonus fact: Roots stabilize soil particles.
What farming practice reduces erosion by plowing along land contours?
Answer: Contour plowing
Bonus fact: Contour lines slow runoff down slopes.
Wind erosion removes and transports what?
Answer: Sediment
Bonus fact: Fine soil and sand are especially vulnerable.
Water erosion is caused by moving what?
Answer: Water
Bonus fact: Rainfall, runoff, rivers, and waves reshape land.
Glacial erosion is caused by moving what?
Answer: Ice
Bonus fact: Glaciers scrape and pluck rock.
Besides river erosion, what geologic process can help deepen a canyon by raising the land?
Answer: Tectonic uplift
Bonus fact: Uplift gives rivers more gravitational energy to cut downward.
Where is erosion usually strongest in a river meander?
Answer: Outer bank
Bonus fact: Water tends to move faster along the outside of a bend.
How can exposed bedrock reach the surface naturally?
Answer: Erosion removes overlying material
Bonus fact: Erosion can strip away soil and sediment to reveal bedrock.
