WebWater slides into cracks and pores in rock and causes the rock to break into smaller pieces. That process is called weathering. There are two primary weathering mechanisms: freeze-thaw and chemical weathering. Water is critical for both of those processes, and there's plenty of water on the Earth. Space probes and ... WebApr 14, 2014 · Ice crystals that are formed during the freeze-thaw process can cause cell membranes to rupture. Rapid freezing results in ice crystal formation in the outer parts of cells, which causes the interior of the cells to expand, pushing against the plasma membrane until the cell bursts.
