upper portions of the grand canyon show undisturbed horizontal layers of sedimentary rock. which of steno’s principles helps explain this? principle of lateral continuity principle of original verticality principle of original horizontality principle of superposition
Answer
Brief Explanations:
Steno's principle of original horizontality states that sedimentary layers are originally deposited horizontally. The undisturbed horizontal layers of sedimentary rock in the Grand Canyon are explained by this principle. The principle of lateral continuity deals with the lateral extension of layers, original verticality is not a correct Steno - principle, and the principle of superposition is about the relative age of layers (younger on top of older).
Answer:
principle of original horizontality
