is because they react to the iron and form rust
Oxidation (The bonding of oxygen to iron in the presence of water) Carbonation (Water + Carbon dioxide --> Carbonic acid) Acid Rain (SO2 or NOx + Water --> Acid Rain) All of the above will cause chemical weathering
Rust is formed when iron reacts with oxygen in the air. It's not erosion, it's a chemical change called oxidation.
The process is called rusting.
Oxidation is the recombination of atoms of one molecule with oxygen. An example might be the rusting of iron: 2Fe(s) + 3O2(g) --> 2Fe2O3(s) Therefore, oxidation is chemical reaction.

It would be a chemical change.
Groundwater causes chemical weathering by speeding reactions between reactive materials. Typical would be an oxidizing reaction, such as the formation of rust in rocks containing iron, or the dissolution of limestone by carbonic acid.
weathering is part of erosion there are two types of erosion mechanical and chemical. chemical refers to elements such as oxygen and Iron which cause a chemical change such as rust and oxidation mechanical weathering is when rocks or materials are separated by water mass movement etc

Rocks are broken down by physical or chemical weathering.
The oxygen in the air combines with the minerals and the rocks change because the minerals are oxidizing. Oxidation can cause new chemical compounds such as iron oxide to form in the rocks.
chemical weathering works faster copper roof turns brown then green after several years in air or in minutes with the right chemicals iron hardware can be browned or blued so the weathering being the universe wind rain air sun = natural vibration annealing sanding peening = mechanical chemical =chemical
Physical weathering physically breaks down the rock, whereas chemical weathering breaks down the rock through chemical changes. For example, physical weathering could break down rock through ice wedging, which occurs when water seeps through the cracks in the rock, freezes, and expands, causing the rock to crack. Chemical weathering could be when oxidation (rusting) occurs, when metal is exposed to water and oxygen. Either way they both break down rock.
The process is called rusting.
