As you go up a sedimentary rock sequence, each layer is younger than the one below it. This principle is based on the Law of Superposition, which states that in any undisturbed sequence of sedimentary rocks, the oldest layers are at the bottom, and the younger layers are deposited on top. This means that as we move upward through the layers, we encounter rocks that were formed more recently.

Additionally, this concept plays a vital role in understanding the geological time scale and provides valuable insights into the Earth's history. By studying the sequence of sedimentary rocks, geologists can determine the relative ages of rocks and the events that may have occurred over geological time, thereby piecing together the history of the Earth.
