Metamorphic Rock Characteristics and Processes

The video tutorial explains the characteristics of metamorphic rocks, focusing on their foliation and increased hardness compared to their sedimentary rock origins. It describes the transformation process from sedimentary to metamorphic rock and highlights the typical presence of foliation in these rocks.

What characteristic is typically found in the metamorphic rock discussed?

• Transparency

• Porosity

• Foliation

• Granularity

From what type of rock did the metamorphic rock originally form?

• Limestone

• Igneous rock

• Sedimentary rock

• Volcanic rock

How does the hardness of the metamorphic rock compare to its original form?

• It is the same

• It is more brittle

• It is harder

• It is softer

What process has the rock undergone to become very hard?

• Sedimentation

• Metamorphosis

• Erosion

• Crystallization

What is typically present in the metamorphosed rock?

• Porosity

• Foliation

• Transparency

• Granularity
