20. The diagram below represents equal masses of two identical rock samples. Sample A is one large block,
while sample B was cut into four smaller blocks of
equal size.

Sample A
Sample B
If subjected to the same environmental conditions,
sample B will weather more quickly than sample A.
The best explanation for this is that the
A) volume of sample B is greater than that of
sample A
B) density of sample A is greater than that of
sample B
C) hardness of sample A is greater than that of
sample B
D) surface area of sample B is greater than that of
sample A
