Similarly, pollen grains released by seed-bearing plants became fossilized in rock layers.

Relative dating methods are used to determine only if one sample is older or younger than another.

Absolute dating methods are used to determine an actual date in years for the age of an object.

Absolute dating contrasts with the relative dating techniques employed, such as stratigraphy.

Absolute dating provides a numerical age for the material tested, while relative dating can only provide a sequence of age.

Exhumed forms may complicate identification and relationships, for both epigene and etch forms have been buried, and exhumed, but in tectonically undisturbed areas, the higher surfaces are older than those preserved at lower levels. The relationship of surfaces with volcanic deposits, old shorelines, and genetically related sedimentary sequences provides sound ages, and correlation with dated duricrusts and faults is also useful.

There are no temporal limits to relative dating, for the methods are equally applicable to the dating, say, of Proterozoic surfaces as of those of Pleistocene age.

To do so successfully, we would need to assure ourselves of the following conditions: Given these conditions, we can find out how long the hourglass has been running.Carbon-14 is an unstable isotope of normal carbon, carbon-12.
