mechanical weathering or disaggregation
Explain how frost wedging contributes to physical weathering.
Explain how frost wedging contributes to physical weathering.
Water expands when it freezes, leading to rock breaking apart through repeated cycles of freeze-thaw.
Describe the process of thermal expansion and contraction in physical weathering.
Describe the process of thermal expansion and contraction in physical weathering.
Heating causes rock to expand, while cooling results in contraction; different minerals expand and contract at different rates.
