Denudation Processes in the Tropics
Geography · 50 practice questions
Weathering, erosion, mass movement and deposition.
- Identify the agents of denudation (water, wind, waves).
- Identify the landforms associated with each denudation process and agent.
Try a few questions
- Practice question 1
Soil creep is a slow, gradual form of mass movement in which soil particles move
- A.upslope, against the pull of gravity
- B.very slowly downslope over time
- C.in a completely random, non-directional manner
- D.very rapidly downslope within a matter of seconds
Show the answer
B. very slowly downslope over time
Soil creep is specifically characterized by its slow, gradual downslope movement, unlike rapid landslides.
- Practice question 2
Exfoliation, a type of physical weathering, involves the peeling away of outer rock layers due to repeated
- A.expansion and contraction from temperature change
- B.biological activity from plant roots and burrowing animals
- C.chemical reaction with dissolved carbon dioxide in rainwater
- D.a process entirely unrelated to temperature or rock structure
Show the answer
A. expansion and contraction from temperature change
Exfoliation is specifically driven by repeated thermal expansion and contraction, causing outer rock layers to peel away.
- Practice question 3
A scree slope, consisting of accumulated loose rock fragments, is a common landform resulting from
- A.chemical weathering in perfectly flat, level areas
- B.biological weathering occurring exclusively underwater
- C.a process entirely unrelated to any form of weathering
- D.mechanical weathering on steep slopes
Show the answer
D. mechanical weathering on steep slopes
Scree slopes are a classic landform resulting from mechanically weathered rock fragments accumulating on steep terrain.
