The statement is true of the undisturbed rock layers shown is
Limestone is the youngest
Most of the rocks exposed at the surface of Earth area unit sedimentary--formed from particles of older rocks that are broken apart by water or wind. The gravel, sand, and dust settle to an all-time low in rivers, lakes, and oceans. These matter particles could bury living and dead animals and plants on the lake or Davy Jones's locker.
