Intro to Superposition. The law of superposition says that if none of the layers have been disturbed, the top layer is youngest and the bottom layer is the oldest. 1. Geologist have dated layer 11 to be 65 million years old. What possible age can layer 12 be? A – 100 MYA B – 10 MYA

The law of superposition says that if none of the layers have been disturbed, the top layer is youngest and the bottom layer is the oldest.
1. Geologist have dated layer 11 to be 65 million years old. What possible age can layer 12 be? • A – 100 MYA • B – 10 MYA • C- 234.5 MYA • D – 1,342 MYA
2. What element would we probably find between layers 11 & 12?
3. If layer 3 is dated to 2.3 billion years ago, what can we say about layers 1 & 2?
