Question

Sample A represents unweathered granite. Sample B represents Weathered granite. M (Fe, Mg)2SiO4 0 - orthoclase feldspar KAISI30g - quartz SiO2 Based on the samples provided, which statement best explains the mineral differences shown?

A. All minerals weather at the same rate.
B. Quartz and olivine weather at the same rate.
c. Olivine is the most resistant to weathering
D. Quartz is the most resistant to weathering.
E. Feldspar and olivine are the most resistant to weathering.​

Answer 1

The mineral differences between the unweathered and weathered granite samples can be explained by the varying levels of resistance to weathering of different minerals.

Step-by-step explanation:

The mineral differences between the unweathered and weathered granite samples can be explained by the fact that different minerals have different levels of resistance to weathering. In this case, the most resistant mineral is quartz, which is why it is still present in the weathered granite sample (Sample B). Other minerals like olivine and feldspar are less resistant and have undergone weathering, resulting in their absence or alteration in the weathered granite sample.
