Scientific law that states in horizontal sedimentary rock, the oldest layers are at the bottom

• intrusion

• fault

• index fossil

• superposition

An intrusion is always ___________ than the rock layers around it and beneath it

• younger

• older

The diagram shows a cross section of rocks beside a highway. 
Which rock type is the oldest?
