A geologist observes rock layers that are folded. She determines that a layer of siltstone is younger than the layer of limestone above it. What conclusion can you draw from the geologist's findings? Explain .

Final answer:

The conclusion is that the siltstone and limestone layers were originally deposited horizontally, and a geological event caused the folding after their formation. The folding indicates a syncline, which suggests a geological event affecting a continuous sequence of sediment.

Step-by-step explanation:

Based on the geologist's observation that the layer of siltstone is younger than the layer of limestone above it in folded rock layers, we can conclude that a geological event occurred after the layers were formed. This is in line with the principle of original horizontality, which states that sedimentary rocks are originally deposited in a horizontal manner, and any folding or tilting occurs after the deposition.

Furthermore, if in a stratigraphic sequence, the rocks get younger towards the inside of a fold, it indicates the fold is a syncline. This can also be an example of the principle of lateral continuity, implying that the folding event occurred post the formation of the layers and affected a continuous and previously undisturbed sedimentary sequence.

Answer:

the findings are incorrect.

Step-by-step explanation:

the geologists finding are incorrect because the layers of soil which is far a way from the sirface of earths is the oldest layer.

was it correct sir?
