Metamorphic Rock — Quiz

Question 4 • Earth and Space Science

How does the progression from sample S1 to S-4 demonstrate the relationship between mineral composition and rock structure during metamorphism?

Answer
A
As minerals break apart into smaller grains, they lose alignment and create weaker foliation across the rock.
B
As minerals dissolve into surface fluids, they leave pores that disrupt the rock's overall foliation pattern.
C
As minerals melt into liquid magma, they cool rapidly and form irregular crystalline foliation throughout the rock.
D
As minerals recrystallize into more stable forms, they align under pressure to create increasingly distinct foliation in the rock.
