How do rocks help prove the law of lateral continuity?

The rock layers on the top were deposited after the tilting event and are again laid down flat. The Law of Lateral Continuity suggests that all rock layers are laterally continuous and may be broken up or displaced by later events. This can happen when a river or stream erodes a portion of the rock layers.Click to see full answer. Just so, what is the law of lateral continuity?The principle of lateral continuity states that layers of sediment initially extend laterally in all directions; in other words, they are laterally continuous. As a result, rocks that are otherwise similar, but are now separated by a valley or other erosional feature, can be assumed to be originally continuous.Likewise, how does lateral continuity explain the relative age of rocks? RELATIVE AGE OF ROCKS Rock layers extend laterally, or out to the sides. They may cover very broad areas, especially if they formed at the bottom of ancient seas. The matching rock layers were deposited at the same time, so they are the same age. Lateral Continuity. Secondly, who invented principle of lateral continuity? The principle of original lateral continuity proposes strata originally extended in all directions until they thinned to zero or terminated against the edges of their original basin of deposition. This was the third of the principles of Niels Stensen (alias Nicolaus or Nicolas Steno) (Dott and Batten, 1976).What is the law of superposition and how is it used?In its plainest form, it states that in undeformed stratigraphic sequences, the oldest strata will be at the bottom of the sequence. This is important to stratigraphic dating, which assumes that the law of superposition holds true and that an object cannot be older than the materials of which it is composed.
