Typically Frost wedging is the process that happens when water fills a crack in the rock, then freezes, and then expands. Larger elements such as boulders and gravel are deposited nearer to the ice margin, while finer elements are carried farther, sometimes into lakes or the ocean. This is a process by which pieces of rocks split off into sheets or leaves beside joints that are parallel to the ground surface. Ba?0T3A0 ` 2.
