← GeographyWhich consequence results when increased precipitation saturates soils overlying shale bedrock?
A)Increased creep slope instability✓
B)Enhanced soil cation exchange
C)Acceleration of loess deposition
D)Suppressed aeolian dust transfer
💡 Explanation
Increased soil saturation reduces soil strength via weathering because water interacts with clay minerals in shale, fostering increased pore water pressure and causing slope instability. Therefore, the effect is increased creep, rather than cation exchange or altered aeolian processes.
