Evolution

The law of superposition states

• the oldest rock layer is on the top, the younger rock layer is on the bottom
• rock layers are always in sequence from oldest to youngest
• the youngest rock layer is on the bottom and the oldest is on the top
• the oldest layer is on the bottom and the youngest is on the top when it is undisturbed
