Which is an example of physical weathering?

a- limestone in rock dissolving when acid rain flows across it

b- bits of rock rusting when exposed to oxygen and water

c- wind blowing off bits of a rock over time

d- oxidation of certain metals in rock

Respuesta :

C
I’m pretty sure the answer is C because physical weathering means is when rock is broken down through mechanical processes such as wind, and C is the only one talking about breaking down (not dissolving) the rock.
I could be wrong.?
