Which mineral is not affected by chemical weathering processes and is common to passive margins?

A) biotite mica
B) olivine
C) quartz
D) feldspars

Explanation / Answer

Question 1 Answer (B) Physical weathering produces fresh surfaces for chemical weathering to attack.

Because physical weathering creates good way to chemical weathering in the form of fresh surface by forst wedging or breaks down of rocks into small pieces.

Question 2 Answer (C) mechanical weathering,it can breakes big rocks into small pieces.

Question 3 (C) Quartz,Quartz is not affected by chemical weathering processes and is common to passive margins.Becuase quartz is highly resistive mineral.
