Frost Wedging:
Frost wedging is the repeated cycle of freezing and cooling of water in a rock’s crack(s). To get frost wedging, first you have to find water in the cracks of a rock. After that, if it is freezing, the cold water will freeze into ice, and since water expands when it freezes, it will expand the crack. Then the ice will melt, and freeze again. The repeated cycle over and over again can spit a once big rock into many smaller rocks. It isn’t the fastest type of mechanical weathering, but it isn’t the slowest. It can also take years to break the rock apart though. It depends on the rock and the location.
