Cornelius sees a landform with almost vertical layers of sedimentary rocks. which of the following statements is most likely true?

the rock is not really sedimentary.
a geologic event shifted the rocks.
the rocks have been undisturbed for millions of years.
water and wind deposited the rocks in vertical layers.

A geological event shifted the rocks

Explanation:

The rock layers have the natural tendency to layer up in horizontal manner, thus to be positioned one above the other. This actually means that the rock layers are sorted out by age, with the ones on the bottom being the oldest ones, and the ones on top the youngest ones. The Earth is not static though, and there's constant movements, geological activities, that disturb the rock layers. If there are geological activities that will push up and than move sideways the rock layers, the rock layers will appear to have vertical layers, not horizontal ones, thus giving a nice clue about how they came to be in that position.
