Question

which of the following is true about the rock layers in the picture above?the rock layers originally formed flat horizontal layers.the rock layers most likely formed from a shallow tropical ocean.the rock layers originally formed in the same positions they are in now.the rock layers are most likely less than a few thousand years old due to their color.

Explanation:

The principle of original horizontality (a key geological concept) states that sedimentary rock layers form as flat, horizontal layers initially. The tilted layers in the image show they were disturbed after formation. There is no evidence in the image to support a shallow tropical ocean origin, and the layers clearly moved from their original position. Rock color does not indicate an age of only a few thousand years, as sedimentary rock formation can take millions of years.

Answer:

A. The rock layers originally formed flat horizontal layers.
