Question

Why do automobiles rust faster in wet climates than in drier climates?

Answer 1

The water helps the car slide just a little bit if you drive in a wet climate but in a dry climate the car does all the work. for example when you slide across ice with sneakers. on a dry surface you cant slide, but an a icy surface you start but the ice does the rest.

Answer 2

Automobiles rust faster in wet climate because  the chemical reaction between the metal and the iron, oxygen or water breaks down, or oxidizes, the metal causing the appearance of rust.
