What principle in relative dating states that in undeformed sequence of sedimentary rock, the layers found at the top are the youngest rocks and layers at the bottom are the oldest?

What principle of relative dating states that in an undeformed sequence is the one where layers are still in a horizontal position?

What relative dating principle state that the geologic layer that cuts another is younger than the layer it cuts across?
