Which of these is not a process of chemical weathering?

dissolving of limestone which makes caves
cracked sidewalk
rusting nail
wearing away of the inscriptions on a New York City monument

Respuesta :

I would go with Rusting nail because lime stone dissolves quick then any other.

Answer:

I say cracked sidewalk because limestone dissloves, rusting nail is a nail getting to many chemicals surrounding it, and the last one is the statue of liberty is surrounded by about of h20 in the air.  why the sidewalk isn't the answer that is because of earthquakes or air bubbles in the cement
