← GeographyWhich process accelerates breakdown via increased surface area?
A)Frost weathering by ice expansion✓
B)Chemical weathering with oxide formation
C)Erosion causing sediment deposition
D)Plant root penetration and expansion
💡 Explanation
Frost weathering accelerates rock breakdown because cyclical freeze-thaw action causes ice wedging, a form of mechanical weathering. Because ice occupies greater volume upon freezing, crack propagation occurs, therefore fracturing rock, rather than oxide formation from chemical reactions.
