Frost wedging occurs when water seeps into cracks and then freezes, causing the rock to break apart. This process is most effective in climates that experience frequent freeze-thaw cycles, which are typically found in moist, temperate climates. In cool high desert areas, there may not be enough moisture for this process to occur frequently. Where the subsoil is permanently frozen, there is not enough water for frost wedging to occur. In a moist, tropical forest, there may be too much vegetation and soil cover to expose enough rock for frost wedging to be effective.
