The absolute dating is also known as the numerical dating as it comes up with the exact numerical age of the item.

This light can be measured to determine the last time the item was heated. Fluctuating levels can skew results — for example, if an item went through several high radiation eras, thermoluminescence will return an older date for the item.

Relative dating utilizes six fundamental principles to determine the relative age of a formation or event.

The first principle is the Principle of Superposition which states that in an undisturbed succession of sedimentary rock, the oldest layers are on the bottom.

For purposes of relative dating this principle is used to identify faults and erosional features within the rock record.

Then, by applying the Principle of Cross-Cutting we are able to relatively date those processes.

The principle of cross-cutting states that any geologic feature that crosses other layers or rock must be younger then the material it cuts across.

Using this principle any fault or igneous intrusion must be younger than all material it or layers it crosses.

The main techniques used in absolute dating are carbon dating, annual cycle method, trapped electron method, and the atomic clocks.

These techniques are more complex and advanced regarding technology as compared to the techniques in practice in the relative dating.

The absolute dating is also sometimes referred as the relative numerical dating as it comes with the exact age of the object.

Much like the principle of cross-cutting, the Principle of Inclusions relatively dates objects based on their placement within other earth materials.

Once a rock is lithified no other material can be incorporated within its internal structure.

Therefore, the piece, or inclusion, must be older than the material it is included in. Aside from single-celled bacteria, most living organism reside at or very near the Earth's surface either in continental or oceanic environments.



Too many shows (eg, ' Sister, Sister' and ' Lizzie Mc Guire') think just because its lead characters are now teenagers then they should tackle social issues and end up losing their humour by being too hard-hitting.… continue reading »
