In law of superposition which layer is the oldest and which layer is the youngest

In law of superposition which layer is the oldest and which layer is the youngest?

Law of superpostion is an axiom that forms one of the bases of the sciences of geology, archaeology, and other fields dealing with geological stratigraphy.  In its plainest form, it states that in undeformed stratigraphic sequences, the oldest strata will be at the bottom of the sequence. The oldest layer would be at the bottem because of how old it is and because of how much other elemnt has been coverd on it. The younges would be on top because it is newer and just got the in the last 100  years.

If you need any help with science questions ask me and here is a picture to

blue is scattered more than other colors because it travels as shorter, smaller waves. this is why we see a blue sky most of the time.
