Answer:
Scientists use waves to study the different layers of the earth. Usually, they use seismic waves, which are waves generated by earthquakes or nuclear-test explosions. The seismic waves are bent, sped up, or slowed down, or even reflected when they pass through the earth's layers.
Seismic waves are recorded by a machine called a seismograph, which tells us about the strength and speed of the seismic waves. ... Seismic waves travel at different speeds when they pass through different types of material, so by studying seismograms, scientists can learn a lot about Earth's internal structure.

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.
