Question

What are two definitions of chemical weathering?

Answer 1

I don't understand what you mean by two definitions of chemical weathering since there are many forms. In general chemical weathering involves the change in the composition of rocks, often leading to a 'break down' in its form. This is done through a combination of water and various chemicals to create an acid which directly breaks down the material. This type of weathering happens over a period of time.
