In undisturbed layers of rock, the oldest rocks are on the bottom and the youngest rocks are at the top.

• Principle of Superposition

• Principle of Lateral Continuity

• Principle of Original Horizontal

• Principle of Cross-Cutting Relationships

Horizontal layers are tilted and uplifted. New sediment is deposited on top.

• Unconformities

• Cross-Cutting

• Angular Unconformities

• Inclusions
