Angular Unconformities Show Evidence of Young Earth Creation Model

​An angular unconformity occurs when horizontal rock layers or nearly horizontal rock layers are deposited on top of sharply inclined rock layers while a sharp gap occurs in between. This sharp gap or unconformity commonly includes significant erosion and old earth geologists recognize this feature, however they assume long time periods between this gap of erosion. Creationists, however, believe that this feature gives strong evidence of a young earth, and in particular the work of the global Genesis Flood. As this year-long flooding event 4,500 years ago was depositing enormous quantities of sediment onto the Earth's surface, it was also eroding large portions of fresh sediment. As creationists believe, there were not large time periods between these erosional breaks caused by the receding floodwaters eroding large portions of the landscape. As these sediments were soft and newly deposited, the receding floodwaters would have easily eroded these sediment layers during the one year duration of the flood before adding new sediment layers which would eventually harden into rock layers. Evidence for quick erosion and deposition of sediment is seen with the nearly planar erosional surfaces, whereas gaps of millions of years proposed by the old-earth model would expose the erosional surface to deep gullies, canyons, and valleys. The planar erosional surfaces observed point toward erosion over a very quick time period during a catastrophic flooding event. (1)
