How can frozen water induce rock weathering
WebIt happens when water enters the pores and cracks of rocks, then freezes. Frost weathering, frost wedging, ice wedging or cryofracturing is the collective name for several processes where ice is present.

The expansion of the … WebThe movement of water can create and modify features on Earth’s surface. This happens through weathering, erosion, and deposition. Weathering occurs when water breaks down rocks and soil to create sediment. There are two main types of weathering: mechanical and chemical. Mechanical weathering is the creation of sediment through physical means.
WebPhysical weathering occurs when physical processes affect the rock, such as changes in temperature or when the rock is exposed to the effects of wind, rain and waves. Water can get into cracks in a rock and, if it freezes, the ice will expand and push the cracks apart. When the ice melts, more water can get into the larger crack; if it freezes ...
