Which of the following pairs are likely products of weathering granite?
A)sandstone and calcite
B)feldspar and mica
C)clay and quartz
D)olivine and pyroxene

Question

Quizplus · Accepted Answer

Granite contains feldspar, quartz, and mica minerals. Weathering of granite leads to the breakdown of these minerals, with the feldspar transforming into clay minerals and the quartz remaining unchanged. Therefore, the likely products of weathering granite are clay and quartz. Sandstone and calcite (A) are not direct products of weathering granite, and olivine and pyroxene (D) are not present in granite. While feldspar is found in granite, weathering of feldspar would not result in the formation of more feldspar (B).
