Relative Dating

Use the diagram and relative dating to determine what is the oldest layer. 

• The bottom layer will contain the oldest fossils
• The top layer will contain the oldest fossils
• It is impossible to tell which layer contains the oldest fossils with out absolute dating
• Layer A and C contain fossils from the same period

Use the diagram and the law of superposition to make a statement about the image. 

• The bottom two layers are generally the same age range
• The bottom layer is most likely the oldest and the top layer is most likely the youngest
• The top two layers cannot be determined because of weathering and erosion that may still be occuring
