Answer
The best example of physical weathering is plant roots splitting rock.
Solution
The best example of physical weathering from the options provided is:
**OD. plant roots splitting rock**
This process involves the physical breaking apart of rock due to the growth of plant roots, which exerts pressure on the rock as they expand. The other options involve chemical processes or actions that do not directly relate to the physical breakdown of rock.

The best example of physical weathering from the options provided is "plant roots splitting rock." This process occurs when the roots of plants grow into cracks in rocks, exerting pressure that can eventually break the rock apart. It’s a fascinating example of nature's strength and the role of living organisms in shaping the landscape! Iron rusting in igneous rock, on the other hand, is a form of chemical weathering. Chemical weathering alters the mineral composition of the rock, while physical weathering, like root growth, preserves the original mineral structure but breaks the rock into smaller pieces. Nature is a clever architect, don’t you think?
