Solution Steps

Step 1: Analyzing the image and the first question

The image shows a cross-section of layered rock strata labeled A through F. The question asks about the relative ages of the layers, assuming a simple "layer-cake" stratigraphy. In such a scenario, the principle of superposition applies, meaning older layers are deposited first, and younger layers are deposited on top.

Step 2: Determining the oldest layer

According to the principle of superposition, the oldest layer will be at the bottom. In the given image, Layer F is at the bottom.

Step 3: Determining the youngest layer

Similarly, the youngest layer will be at the top. In the given image, Layer A is at the top.

Final Answer

a. Layer A (Youngest) b. Layer C c. Layer D d. Layer E

Step 1: Understanding what fossils _cannot_ reveal

Fossils provide a wealth of information about past life forms and their environment. They can tell us how life has changed over time, how environments have shifted, and even give clues about geological changes. However, they do _not_ directly reveal information about changes in the surrounding rock _after_ fossilization has taken place.

Final Answer

\\(\boxed{\text{d. How the surrounding rock layers have changed over time}}\\)

Step 2: Identifying evidence for superposition

The Law of Superposition states that, in undisturbed sedimentary rock layers, the oldest layers are on the bottom and the youngest layers are on the top. This law was developed based on observations of both rock layers and the fossils within them.

Final Answer

\\(\boxed{\text{c. Rock layers and fossils}}\\)
