Answer:

B. Deposition of new layers of sediments

Explanation:

This does not affect a metamorphic process.

It has effect on sedimentary process. New layers of sediments can help to compact the underlying ones and makes the sediments more lithified.

Answer:

All of the given are factors that affect "metamorphic processes" except "deposition of new layers of sediment".

Explanation:

  • The chemistry of metamorphic rock is same as its parent rock. Example quartz will metamorphose into silica. Limestone will metamorphose into calcium rich rock.
  • Temperature and pressure are the important factors which affect metamorphic processes. Minerals are formed under different temperatures and pressures.
  • The chemical reactions also occur at various temperatures during metamorphism.
