Answer

Brief Explanations:

The task requires matching geological terms related to metamorphism and lithification with their correct descriptions.

  1. Compaction is the process where physical pressure from overlying sediments reduces pore space, causing grains to move closer together.
  2. Foliation refers to the repetitive layering or parallel alignment of platy minerals (like mica) in metamorphic rocks due to directed pressure.
  3. Recrystallization occurs when minerals change size or shape without changing their chemical composition, often resulting in larger grain sizes.
  4. Burial metamorphism occurs when rocks are buried deep within the Earth's crust, changing due to the high lithostatic pressure and temperature of the surrounding environment.

Answer:

  1. Grains move closer together: Compaction
  2. Parallel alignment of platy grains: Foliation
  3. Grains take on a larger size: Recrystallization
  4. When a rock changes because of surrounding pressure: Burial metamorphism
