Which of the following geologic principle is directly applicable to a tilted layer of the Grand Canyon originally being deposited in a flat, horizontal manner?
A) The principle of superposition states that sediments accumulate in horizontal layers and are tilted or folded after deposition occurs
B) The principle of crosscutting relationships states that sediments accumulate in horizontal layers and are tilted or folded after deposition occurs
C) The principle of original horizontality states that sediments accumulate in horizontal layers and are tilted or folded after deposition occurs
D) The principle of included fragments states that sediments accumulate in horizontal layers and are tilted or folded after deposition occurs on
E) The principle of faunal succession states that sediments accumulate in horizontal layers and are tilted or folded after deposition occurs

The principle of original horizontality states that sediments are deposited in horizontal layers, therefore the fact that a layer in the Grand Canyon is now tilted indicates that it was originally deposited horizontally and then subsequently tilted by geologic forces.
