text: refreezing of water can changea rock by-fracturing it,eroding the surface,shattering it,change its composition   figuring out some of these questions is like doing a puzzle....  okay, i get it. this is multiple choice. the best answer is: fracturing it or shattering it  water will cleave the rock by expanding within it as it freezes. freezing by itself will not erode the surface (this is meant to be a chemical process) except by fracturing. it might shatter from freezing. same process of expansion of water when freezing. changing it's composition? no this is a chemical process, not physical erosion.  got it?
