Question 7 (3 points)
which of the following describes the law of original horizontality?

"Folded sedimentary layers were originally laid down flat and later deformed." describes the law of original horizontality.

Explanation:

In terms of structural geology, the folds happens when the one over the another are piled up on a flat as well as planar structure i.e. sedimentary strata. Which sometimes are bent or may be curved because of the permanent deformation. Both upward as well as downward folds occurs in the sedimentary fold. Which is known as the anticline or the syncline. There are three major folds in case of the sedimentary layers they are monocline, anticline and syncline. Simple bend layers are called as the monoclines.
