Which of steno’s principles is responsible for the thin undisturbed layers found in the grand canyon?

a. principle of superposition

b. principle of original horizontality

c. principle of original lateral continuity

d. principle of faunal succession

The right option is; C.principle of original lateral continuity

Principle of original lateral continuity is responsible for the thin undisturbed layers found in the Grand Canyon.

The principle of lateral continuity states that layers of sediment are originally deposited laterally in all directions. This means that layers of sediment are laterally continuous. For this reason, rocks that are similar but are now divided by any erosional feature such as a valley can be surmised to be continuous initially.
