Which principle states that in a sedimentary sequence, the oldest layer lies at the bottom and the youngest layer at the top

Respuesta :

Answer: Principle of Superposition

Explanation: In an otherwise undisturbed sequence of sedimentary strata, or rock layers, the layers on the bottom are the oldest and layers above them are younger. Principle of Original Horizontality: Layers of rocks deposited from above, such as sediments and lava flows, are originally laid down horizontally. Hope this helps!
