Question

choose the statement that best describes foliation. choose one: a. the texture typical of all metamorphic rocks b. an arrangement of mineral grains such that most are of the same size and shape c. an alignment of mineral grains perpendicular to the direction of compression d. an alignment of mineral grains parallel to the direction of compression

Answer 1

d. An alignment of mineral grains parallel to the direction of compression describes foliation.

Step-by-step explanation:

Foliation is a characteristic feature of many metamorphic rocks, and it refers to the alignment of mineral grains or other constituents in parallel planes or layers. This alignment is typically a result of the application of directed pressure or compression during the metamorphic process, which causes the mineral grains to flatten and orient in the same direction. The resulting texture can give the rock a layered or banded appearance and can also affect its physical properties such as its strength and cleavage.
