Overstep describes the relation in which beds above an unconformity

  • A.rest successively on different underlying formations
  • B.are entirely absent over a wide area
  • C.dip more steeply than those beneath
  • D.have been faulted against those beneath

Answer: A

Because the surface bevels across a tilted sequence, the same bed above may lie on one formation here and on another a kilometre away. It is direct evidence that the lower rocks were tilted before the upper were laid down.
