The best example of physical weathering is as follows:
Thus, the correct option for this question is B.
Weathering may be defined as a process through which numerous rocks and minerals found on the earth's surface are considerably broken down into smaller fragments. The process of weathering is facilitated by different components like water, wind, ice, etc.
Physical weathering may be defined as a type of process that stimulates the disintegration of rocks, minerals, and soil components without undergoing any chemical change. Some examples of physical weathering are as follows:
Therefore, plant roots grow through concrete and split represents a process of biological activities or root wedging. So, the correct option for this question is B.

Answer:
Plant roots growing through concrete and splitting it.
Using the rock cycle, it shows that with heat and pressure, an igneous rock can turn into a metamorphic rock.
Explanation:
This is incorrect because it can also convert to sediments by weathering, erosion, and deposition. The Rock Cycle is a group of transformations. Igneous rock can transform into sedimentary rock or into metamorphic rock. Sedimentary rock can transform into metamorphic rock or into igneous rock. Metamorphic rock can convert into an igneous or sedimentary rock.
