Question

All over Europe there is growing concern about the rapid weathering of the statues and architecture over the past 50 years. Some roman statues have aged more over the last few years than in the previous 2000 years. If most statues are made of marble, do you think the process of weathering the statues is physical or chemical?

I believe it's physical, as this hints to this being towards erosion due to wind.

Answer 1

I would not discount the chemical aspects of the weathering. I am a chemist.
