Answer to Question 1

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.
