Answer

Explanation:

Step1: Recall principle of stratigraphy

In undisturbed rock - strata, the oldest fossils are at the bottom and the youngest are at the top.

Step2: Identify oldest fossil

Fossil C is at the bottom - most layer, so it is the oldest.

Step3: Identify youngest fossil

Fossil A is at the top - most layer, so it is the youngest.

Step4: State evidence for relative age

The position of the fossils in the strata is the evidence. The lower the fossil in the strata, the older it is.

Answer:

  1. C
  2. A
  3. Fossil C was lowest in the strata, meaning that it was deposited first.
  4. Fossil A is the youngest as it is highest in the strata.
