have occurred
approximately 4.1 to 3.8
billion years.

- Is a system of chronological dating
that relates geological strata to time.

- Layers of the Earth
- The internal structure of the Earth is layered in
spherical shells: an outer silicate solid crust, a
highly viscous asthenosphere and mantle, a liquid
outer core that is much less viscous than the
mantle, and a solid inner core.

- Stratigraphy
- the branch of geology concerned
with the order and relative
position of strata and their
relationship to the geological time
scale.

- Fossil record
- fossil record. A term used by paleontologists
(see paleontology) to refer to the total number
of fossils that have been discovered, as well as
to the information derived from them.

- Relative Dating
- Relative dating is the science of
determining the relative order of past
events (i.e., the age of an object in
comparison to another), without
necessarily determining their absolute age.

- Absolute dating
- Absolute dating is the process of determining an age on a specified
chronology in archaeology and geology. Some scientists prefer the terms
chronometric or calendar dating, as use of the word "absolute" implies an
unwarranted certainty of accuracy.
