Choose the correct answer
A
their porosities will be different
B
their densities will be different
C
their degrees of saturation will be different
D
the size range of their voids will be different
Correct Answer
D. the size range of their voids will be different
Why is this the answer?
At the same void ratio, clay has much finer voids than sand, so the void-size range governs the difference in permeability.
