They cracked at an angle.
They were deposited at an angle.
They were deposited vertically and then shifted by a geologic event.
They were deposited horizontally and then shifted by a geologic event.

According to the principle of original horizontality, sedimentary rock layers are initially deposited in horizontal layers. The flat sedimentary rock layers in the foreground likely represent the original horizontal deposition. The angled sedimentary rock layers in the background suggest that they have undergone a geological event that altered their position.
Thus, the most likely explanation for the angled layers in the background is that **they were deposited horizontally and then shifted by a geologic event.**
