Chemical weathering generally proceeds __.
A) at about the same rate throughout a rock body
B) fastest in the intact interior of a rock body, where ions easily move short distances from grain to grain
C) fastest on flat joint (crack) faces that are distant from any corners or edges
D) along contacts between mineral grains
E) fastest at the tip of growing cracks deep within the rock

Question

Quizplus · Accepted Answer

Chemical weathering typically occurs most rapidly along the contacts between mineral grains where there is more surface area exposed to chemical reactions. This is because weathering agents such as water, oxygen, and acids can more easily penetrate and react with the minerals at these contacts, leading to the breakdown of the rock.
