WebThe results show that freeze-thaw weathering at different freezing temperatures does not significantly influence the Young’s modulus of tonalite. This can be attributed to the low porosity of the tonalite specimens. ... Based on analysis of the results of the experiments carried out in this work, the factors that affect the mechanical ... WebFreeze-thaw weathering is common in mountainous areas where the temperature is around freezing point. This type of weathering is caused by the expansion and contraction of water within porous rocks. As ice crystals form, they grow larger, attracting liquid water from the surrounding pores. WebJul 31, 2024 · Definition: Freeze-thaw weathering is a process of erosion that happens in cold areas where ice forms. A crack in a rock can fill with water which then freezes as the temperature drops. As the ice expands, it pushes the crack apart, making it larger. This process continues until the rock breaks.
