Both sedimentary and metamorphic rocks exhibit layering. Explain how the layers develop for each rock type and give the name for the layering
What will be an ideal response?
Answer: Sedimentary rocks form layers through deposition. The sediment is compacted and cemented (lithified) to create a sedimentary rock. This type of layering is called bedding. Metamorphic rocks may develop layers when differential stress is applied to the rock. The minerals become reoriented and realigned at right angles to the stress. This type of layering is called foliation.
