Answer:
newer/newly added layers are on top
Step-by-step explanation:
The Law of Superposition explains that within a sequence of layers, the oldest layer is on the bottom end (the oldest rock layers are formed first). This analogy makes sense because as the week goes on, more clothes are thrown on top of the existing pile of clothes; a shirt you wore on Monday is deeper down in the laundry basket than a shirt you wore on Thursday.
