Tools used to determine Absolute Age and Relative Age
,Objectives:
Distinguish between absolute dating
and relative dating.
Review law of superposition.
Discuss the importance of half-life and
radioactive decay.
Conduct activity on relative and
absolute dating.
,The law of superposition states that
older sedimentary rocks were
deposited prior to younger
sedimentary rocks, therefore, as one
ascends a rock face with multiple
formations, the oldest rock layer is
on the bottom and the rock units get
progressively younger as one
ascends the exposure.
, The law of faunal succession
states that as one views
progressively older fossils, they
become more and more dissimilar
with modern forms of life with
which we are most familiar.
