Quizplus · Accepted Answer

Original horizontality, original continuity, and superposition are all principles that are a result of gravity. Original horizontality refers to the idea that sedimentary layers are deposited horizontally due to the force of gravity. Original continuity refers to the fact that layers of sediment extend laterally in all directions until they thin out or reach a barrier. Superposition refers to the idea that in an undisturbed sequence of rock layers, the oldest layer is on the bottom and the youngest layer is on the top. Cross-cutting relationships, on the other hand, are not directly related to gravity; they refer to the idea that a feature must be younger than any feature it cuts across or through.
