Process of freeze thaw weathering
WebbA freeze-thaw cycle (FTC) occurs when air temperature drops low enough to freeze water (32°F), then increases enough for it to thaw again. FTCs usually occur most frequently in … WebbFreeze-thaw weathering The main type of mechanical weathering that affects coasts is called freeze-thaw weathering. It occurs when rocks have holes (are porous) and are permeable (water can pass through them) because water enters the rocks and freezes.
