{{Main|Geology of Kansas}}

Kansas is underlain by a sequence of horizontal to gently westward [[Strike and dip|dipping]] [[sedimentary rock]]s. A sequence of [[Mississippian age|Mississippian]], [[Pennsylvanian (geology)|Pennsylvanian]] and [[Permian]] rocks outcrop in the eastern and southern part of the state. The state's western half has exposures of [[Cretaceous]] through Tertiary sediments, the latter derived from the [[erosion]] of the [[Tectonic uplift|uplifted]] [[Rocky Mountains]] to the west. These are underlain by older Paleozoic and Mesozoic sediments which correlate well with the outcrops to the east. The state's northeastern corner was subjected to [[glaciation]] in the [[Pleistocene]] and is covered by [[glacial drift]] and [[loess]].
