states that groups of plant and animal fossils appear in a definite order in the geologic record.
These assemblages can be utilized to pinpoint specific geologic periods; 4) Crosscutting relations
principle:
cuts across. The other rock unit has to be present for the igneous rock or fault to cut through it; 5)
Inclusion Principle: A rock unit containing prior rock inclusions must be younger than the rock unit
from which the inclusions originated and 6) Metamorphic rocks: Metamorphic rocks are always
fault or igneous rock unit crossing another rock unit must be younger than the unit it
older than the surrounding non-metamorphosed rocks. If the metamorphic rock developed
before the surrounding rocks, they would have metamorphosed as well.
