In temperate climates, water can infitrate sedimentary rocks (and other types as well), and with repeated freeze-thaw cycles, can break the rocks apart by the physical weathering process of frost/ice …
WitrynaFrost weathering is also known as ice wedging. It is the collective term for various processes that involve ice. The processes include: Freeze-thaw Frost Wedging Frost shattering Frost weathering occurs largely in mountain areas where the temperatures are close to the freezing point of water. Witryna1 kwi 2024 · Physical weathering of building stones induced by freeze–thaw action: a laboratory long-term study J. Ruedrich, D. Kirchner, S. Siegesmund Geology 2011 Damages to natural building stones induced by the action of frost are considered to be of great importance. Commonly, the frost resistance of building stones is checked by …
WitrynaFreeze-thaw weathering occurs when rocks are porous (contain holes) or permeable (allow water to pass through). Water enters cracks in the rock. When temperatures drop, the water freezes and... The traditional explanation for frost weathering was volumetric expansion of freezing water. When water freezes to ice, its volume increases by nine percent. Under specific circumstances, this expansion is able to displace or fracture rock. At a temperature of -22 °C, ice growth is known to be able to generate pressures of up to 207MPa, more than enough to fracture any rock. For frost weathering to occur by volumetric expansion, the rock must have almost no air that can be com…
