← GeographyWhich mechanism impacts building foundations near transform faults?
A)Creep along the fault line✓
B)Sudden liquefaction of supporting soils
C)Cyclical frost heave and thaw
D)Progressive chemical weathering of bedrock
💡 Explanation
Creep causes gradual deformation because asperities prevent continuous sliding, rather than sudden failure; elastic strain accumulates past the static friction limit until slip occurs. Foundation offsets arise with creep rather than liquefaction or frost action, that are instead caused by shaking or soil moisture.
