B)the crack surfaces not including edges and corners
C)the edges and corners
D)All of the above show equal rates.

Question

Quizplus · Accepted Answer

The edges and corners of the granitic block experience the highest rate of weathering because they have the highest surface area to volume ratio. Water can penetrate more easily along these edges and corners, leading to physical and chemical weathering processes that break down the rock more rapidly. The unfractured interior and crack surfaces may also experience some weathering, but at a slower rate than the edges and corners.
