← GeographyWhich outcome occurs when freeze-thaw weathering impacts mountainous regions?
A)Increased frequency of rockslides✓
B)Decreased rates of glacial flow
C)Stabilization of soil horizons
D)Reduced deposition of loess
💡 Explanation
Increased rockslide frequency occurs because freeze-thaw action expands water in cracks, widening them via frost wedging; therefore, instability is created, rather than stable horizons. Glacial flow is altered by temperature changes far more than freeze-thaw cycles.
