This diagram illustrates a geological cross-section used to teach relative dating, featuring folded sedimentary layers, an igneous intrusion, a fault line, and multiple unconformities labeled with letters.

Let me carefully examine the image to understand what the task is asking.

The image shows a geological cross-section labeled “DETERMINING RELATIVE AGE” with layers labeled A through H and features like unconformities and a fault. The question likely asks to order the layers from to youngest using principles of stratigraphy (like superposition, cross-cutting relationships, and unconformities).

I need to determine the relative ages of the labeled units: A, B, C, D, E, F, G, H.

Let me zoom in on key parts to identify the sequence clearly.
