Questions
In оne аreа оf the wоrld, sаmples 7–9 and sample Y are seen together in an outcrop. Your colleague sketched the stratigraphic column below. Based on their illustration, which of the following statements can you conclude are TRUE? Visual Description On the right side of the diagram is a vertical list of labels reading, from top to bottom: Sample 7, Sample 8, Sample 9, Unconformity, and Sample Y. On the left side is a vertical stack of patterned layers that correspond to those labels. At the top, the layer labelled Sample 7 is drawn with a brick-like rectangular block pattern, suggesting a well-lithified, blocky rock unit. Below it, the layer labelled Sample 8 is shown with thin, horizontal lines, indicating a finely layered or laminated sedimentary rock. Below that, Sample 9 is represented by a pattern of small dots, indicating a granular or sandy sediment. Below Sample 9 is a wavy red horizontal line, labelled Unconformity. This line is irregular and undulating, clearly marking a break in deposition or an erosion surface between older and younger rocks. Below the unconformity is Sample Y, shown as a thicker unit filled with scattered red and black dots within a lighter background, indicating a different sediment type or a more poorly sorted or mixed deposit.
