Specifically, the Great Flood is claimed to be the origin of most of the Earth's geological features, including sedimentary strata, fossilization, fossil fuels, submarine canyons, salt domes, and frozen mammoths.
Creationists regard Genesis as providing a scientifically accurate record for the geological history of the Earth, but some claim this is not accepted within the science of geology. This segment of the scientific community state that flood geology is pseudoscience.
Flood geology is a part of the broader endeavor of creation science, particularly being associated with proponents of Young Earth creationism. Flood geology adherents support their views with geological field work that they believe gives strong evidence of a universal flood, and they usually profess a literal belief in the Biblical record as their baseline for research.
Mainstream science does not consider the young earth biblical interpretation of a global flood and associated deluge mythology to be a valid scientific theory. Although flood geology was widely supported by early practitioners of geology and geosciences, it was contradicted by many scientific discoveries of the first half of the 19th century and it was abandoned as a serious scientific hypothesis by the middle of the century. It was revived in the early 20th century as part of the growth of the Christian fundamentalist movement in the United States.
