See this article: Soft-Sediment Deformation: Recent Flood Evidence
Evolutionists and creationists have different views on the origin of sedimentary rock strata. Evolutionists, who uphold the uniformitarian doctrine of 19th-century geologists, suppose that sediments were deposited slowly over millions of years and then hardened into sedimentary rock. This means that soft sediments, however they accumulated, would surely have lithified (hardened into rock) over excessively long periods of time. However, some of these rocks seem to demonstrate the opposite—these layers were clearly deformed before they had time to lithify.
Creationists who hold the catastrophist doctrine of Scripture propose that most sedimentary strata were deposited rapidly by Noah’s Flood. They may have undergone deformation soon thereafter, and the total time span of this process represents only thousands of years.
