Relative dating is done by comparing rock layers and features to each other. Choose which statements are true about the sequence of undisturbed sedimentary rock layers.

• The rock layers are older on top and youngest on top

• The rock layers are younger on top and older as you go toward the bottom.

• A fault that cuts through a rock layer is youngest than the rock layer

• The rock layers are younger on top and older as you go toward the bottom.
