Answer :
Replacement is the molecule-by-molecule substitution of another mineral of different composition for the original material. The fine details of shell structures and wood are generally preserved. Minerals which commonly replace hard parts are silica and pyrite
Answer:
False
Replacement is not the molecule by molecule substitution of another mineral of different composition for the original material
Explanation:
Substitution pseudomorph a mineral that is able to replace another one after appearing in a substitution process. The volume, amount, and dimensions are the same but the element is different. This can't happen with regular elements only with substitution pseudomorphs. Substitution as a process doesn't exist. However, a phenomenon called substitution reaction exists, this process is when a functional group is replaced by another one. But not simply substitution. Therefore, the correct asnwer is false.
