How does frost action cause weathering
WebFrost action is an effective form of mechanical weathering. When water trickles down into fractures and pores of rock, then freezes, its volume increases by almost 10 percent. This causes outward pressure of about 30,000 pounds per square inch at -7.6 Fahrenheit. digitalatlas.cose.isu.edu. What is the meaning of frost wedging?
