It's called chemical weathering. Think acid rain.
The type of weathering that does not alter the chemical composition of the rock is called physical weathering. The acid weathering usually alter the chemical composition of a rock.
Rust is chemical weathering. It occurs when oxygen from the air reacts with a metal, typically with iron. This chemical reaction is called oxydation, and the product is what gives rust its reddish color.
It is classified as physical or mechanical weathering.
Chemical weathering.
The component of granite that is not susceptible to chemical weathering is called Quartz!
This is known as hydrolysis. For further information, please see the related link.

It's called dissolution, a form of chemical weathering.
It is classified as physical or mechanical weathering.
Chemical weathering.
chemical weathering
It is actually called weathering, but if your talking about the process of rocks breaking down into smaller pieces by physical means it is called Mechanical Weathering, by chemical means it is called Chemical Weathering.
One kind of Mechanical Weathering is called ice wedging.
