Which principle tells you how rock layers are laid?A.UniformitarianismB.Faunal successionC.Correlative datingD.Original horizonality

The correct answer to the question is D. Original horizonality.

Explanation:

1. Original Horizonality Principle: This principle states that layers of sediment are originally deposited horizontally under the action of gravity. If the layers are found tilted or folded, it indicates that tectonic processes have occurred after deposition.

2. Uniformitarianism: This principle asserts that the same processes that operate in the present day also operated in the past, but it primarily refers to geological processes rather than the arrangement of layers specifically.

3. Faunal Succession: This principle involves the use of fossil assemblages to characterize and correlate rock layers but does not specifically address how the layers are laid.

4. Correlative Dating: This involves matching rock layers from different locations based on their age or fossil content, but it also does not directly explain how the layers were deposited.

In summary, the principle that specifically addresses how rock layers are laid down is the principle of Original Horizonality.
