WebFreeze-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... WebFrost wedging is the process by which water/ ice weathers and erodes landscapes through repeated freeze and thaw cycles. As water freezes it expands by 9 percent, wedging the rock apart only to melt again during the summer months.
