Which factor affecting metamorphic process is most likely to cause foliation in a rock?
A) Temperature
B) Presence of water
C) Time
D) Pressure
Answer (2)
The factor most likely to cause foliation in a rock during metamorphism is Pressure , which aligns mineral grains. Although temperature, the presence of water, and time play roles in metamorphism, pressure is the primary factor responsible for foliation. This leads to the development of layered structures in metamorphic rocks.

The factor that most likely causes foliation in a rock during the metamorphic process is pressure, as it leads to the alignment of mineral grains. While temperature, the presence of water, and time contribute to metamorphism, pressure is the primary driver behind foliation. Understanding this helps in distinguishing between different types of metamorphic rocks. ;
