All rain is acid rain, but the strength differs. What the acid in rain does is break down all sorts of things, but mostly calcium related thing. However, there is that other name of rust. Iron what? It shows up in one of the answers too.

Answer 11

Now you are getting it. Rust is iron oxide. It is right in the name. And all sorts of things get oxidized. It is a very common chemical reaction. All the moisture it needs to help it is the morning dew, so rain is not required.

Answer 12

O_O

Answer 13

Mechanical weathering by wind is everything from things getting blown loose to sand blasting.

Ice wedging is simple too. Know how ice expands? So you get a little water in a crack in the day time. It freezes that night. The ice expands. It wedges apart the rock just a little. Perhaps a fraction of a millimeter! Now repeat over every warm enough day to melt and cold enough night to freeze.

Answer 14

Answer 16
