Suppose you see a large boulder with several cracks in it. What would you expect to see if you could observe the boulder again in several hundred years?
Mechanical weathering (also called physical weathering) breaks rock into smaller pieces. These smaller pieces are like the largest rock, only smaller. That means that the rock has physically changed without changing its composition. The smallest pieces have the same minerals, in the same proportions as the original rock.
There are many ways that rocks can be broken into smaller pieces. Ice wedging is the primary form of mechanical weathering in any climate that regularly cycles above and below freezing (Figure 2). Ice wedge formation works quickly, breaking rocks in areas with temperatures that oscillate above and below freezing during the day and night, and also that cycle above and below freezing with the seasons.
