Question

it is more reasonable to explain folded sedimentary rocks as a result of _____.
○ long eras of steady pressure
○ deforming of brittle rocks plastically
○ relatively rapid folding of soft sediments

Explanation:

Folded sedimentary rocks are typically formed by long - term steady pressure that causes the rock layers to bend. Brittle rocks don't deform plastically easily to form such folds, and soft sediments usually get compacted rather than rapidly folded to form the characteristic folded sedimentary rock structures.

Answer:

long eras of steady pressure
