The principle of original horizontality states that layers of sediment are originally deposited horizontally under the action of gravity. The observation of tilted rocks below an unconformity at Siccar Point indicates that these rocks were deposited horizontally and then tilted and eroded before the deposition of the newer layers above the unconformity. This principle helps to determine the sequence of these geological events.
