---|---|---|---|---|---|
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
🗑
