Which of the following is not an example of physical weathering
A. wind blowing and eroding sandstone
B. Acid rain disolving limestone
C. Ocean waves crashing against basalt
D. A river carving out a canyon through bed rock
Ocean waves crashing against basalt. All of the other options are eroding rocks. Ocean waves crashing against basalt does not imply that the waves are eroding the basalt. Hope this helps!
