| Term | Definition |
| Catastrophism | earth's landscapes has been formed by great catastrophes, sudden and worldwide disasters |
| Uniformitarianism | the forces and processes that we observe today have been at work for a long time |
| Relative Dating | events in their proper sequence of formation |
| Numerical Dating | actual number of years that have passes since an event occurred |
| Eons | Hadean, Archaen, Proterozoic, Panerozoic |
| Of Geologic Time is Precambrian | 88% |
| Eras | Precambrian, Paleozoic, Mesozoi, Cenozoic |
| How much time is divided | eon (most), era, period, epoch (least) |
| Conformable | strata sequence that is undisturbed |
| Originally Horizontally | all bed originally deposited in water formed close to the horizontal |
| Law of Superstition | within a sequence of undisturbed sedimentary or volcanic rocks, layers get younger as you go up |
| Cross-Cutting Relationship | when the fault cuts through other rock or magma intrudes and crystallizes, the full or intrusion is younger than the rocks affected |
| Unconformity | gaps in the geologic record that may indicate episodes of crustal deformation, erosion, and sea level variation |
| Disconformity | force/erosion that took away top layers; large gap in geologic time due to processes of erosion |
| Angular Unconformity | younger strata overlie an erosion surface on tilted or folded rocks |
| Nonconformity | IGNEOUS or metamorphic rock; magma chamber intrudes, then erosion takes away top layer and builds up again |
| Inclusions | pieces of one rock until that are contained within another; The Rocks Mass Adjacent to the One Containing the Inclusions Must Have Been There First in Order to Provide the Rock Fragment |
