Geologic History Review

Original Horizontality =

rock strata are deposited in (tilted, vertical, horizontal) layers.

• tilted

• vertical

• horizontal

Evidence of crustal movement:

(tilting, folding, faulting)

• tilting

• folding

• faulting

• all

Principle of Superposition =

Top = (younger, older)

Bottom = (younger, older)

• younger, older

• older, younger

• older, older

• younger, younger

Intrusions and faults are relatively (younger, older) than the rock they are in.

• older

• younger

Submergence leads to (sedimentary, igneous) rock formation

Emergence (uplift) leads to (erosion, deposition)

• sedimentary, erosion

• sedimentary, deposition

• igneous, erosion

• igneous, deposition

Unconformity =

buried (erosional, depositional) surface

(flat, bumpy) lines in an outcrop

gap in geologic (time, distance)

• erosional, bumpy, time

• erosional, flat, depositional

• depositional, bumpy, distance

• depositional, flat, time

Geologic Time Scale divided up into eons, eras, periods and epochs by (seismic, fossil) evidence

• sesimic

• fossil

Correlation = matching distant rock by looking at characteristics of rock layers and (isotopes, index fossils)

• isotopes

• fossil

Fossils are only found in (igneous, metamorphic, sedimentary) rock

• igneous

• metamorphic

• sedimentary

Good index fossils =

(narrow, wide) geographic distribution

lived for a (short, long) geologic time period

• narrow, long

• narrow, short

• wide, short

• wide, long
