Scientists can figure out the relative age of fossils and match layers that have been shifted or modified. 2. Horizontal layering in sedimentary rocks is called bedding or stratification. They are horizontal where sediments are deposited as flat-lying layers, and they exhibit inclination where the depositional site was a sloping surface.
