e. unconformity a. conglomerate b. sandstone c. clay d. limestone f. siltstone
a. conglomerate b. sandstone e. unconformity c. clay d. limestone f. siltstone
a. conglomerate b. sandstone c. clay e. unconformity d. limestone f. siltstone

Explanation:

Step1: Principle of Superposition

In undisturbed sedimentary rock layers, the oldest layer is at the bottom. Here, layer A is at the bottom.

Step2: Identify Rock Types

From the legend, A is Conglomerate. Then moving up, B is Sandstone.

Step3: Unconformity

Unconformity (E) is a surface of erosion or non - deposition. After B (Sandstone), there is an unconformity (E).

Step4: Post - Unconformity Layers

After the unconformity, the next layers are C (Clay), D (Limestone), and F (Siltstone) from bottom to top (younger to youngest among them).

Answer:

A. Conglomerate, B. Sandstone, E. Unconformity, C. Clay, D. Limestone, F. Siltstone
