Question

select the correct layers.

which two layers are approximately the same age?

core sample 1
core sample 2

Explanation:

Identify index fossils

We examine the fossils in both core samples.
The orange coiled shell fossils (ammonites) serve as Index Fossils.

Match corresponding layers

We locate the layers containing these identical fossils.
The bottom layer of core sample 1 contains the orange fossils.
The top layer of core sample 2 contains the same orange fossils.

Determine relative age

Using Index Fossils, layers with the same fossils are the same age.
Therefore, these two specific layers are approximately the same age.

Answer:

The two layers that are approximately the same age are:

• The bottom layer of core sample 1
• The top layer of core sample 2
