Question
Which of the following rock types is most likely to have rock material properties that vary with orientation? Group of answer choicesMarbleLimestoneSchistGranite
Solution
C. Schist
Schist is a metamorphic rock that is characterized by its foliated structure, meaning it has a layered or banded appearance that is produced by exposure to heat and directed pressure. This foliation often results in the alignment of mineral grains in a preferred orientation, which can cause the rock's material properties to vary with orientation. This property is known as anisotropy. Therefore, among the options provided, schist is the rock type most likely to have rock material properties that vary with orientation.
