WebMay 6, 2024 · Mechanical weathering (also called physical weathering) breaks rock into smaller pieces. These smaller pieces are just like the bigger rock, just smaller. That means the rock has changed physically without changing its composition. The smaller pieces have the same minerals, in just the same proportions as the original rock. WebWater seeps into the cracks of rocks and freezes when the temperature decreases. This water expands in the process of freezing. Ice acts like a wedge that deepens and widens cracks (ice wedging). When the ice melts, the remaining water seeps deeper and the process starts again. The cracks slowly expand until pieces of rock break off.
