Which outcome accelerates physical soil degradation when exposed?

💡 Explanation

Frost cracking expands water trapped in cracks due to freeze-thaw cycles and mechanical weathering, because the ice volume grows and stresses the material far beyond its cohesive limits. Therefore particle detachment is favored rather than chemical changes or dissolution.
