Answer: It follows the law of original lateral continuity.
Explanation: Sediment is something that settle down in the liquid.
Law of Original Horizontality: This law states that the rocks and sediments are deposited horizontally.
Law of Superposition: This law states that the younger rocks are deposited or super imposed on the oldest rocks.
Law of Original Lateral Continuity: This law states that the sediment layers extent laterally or horizontally in all the direction as the younger rocks are added to the older rock which means that they are laterally continuous.
Law o Gravity and oppositional force: This law states that each particle attracts every other particle in the universe and is directly proportional to the product of the masses of two particles and inversely proportional to the square of the distance between them.
Law of cross-cutting relationship: This law states that fault which is cutting the rock is always younger than the rock.
From the above explained Law's, it is clear that the sediment follows Law of original lateral continuity.
