← GeographyWhich outcome commonly occurs from increased silt weathering in loess deposits?
A)Elevated PM10 dust storm frequency✓
B)Decreased riverine sedimentation rates
C)Accelerated chemical rock weathering
D)Increased cryospheric permafrost stability
💡 Explanation
Intense weathering destabilizes loess structure, leading to fine silt particles becoming easily airborne via saltation; therefore, increased silt weathering raises PM10 frequency rather than affecting sedimentation, rock weathering types, or cryogenic processes.
