the geologic column is used for identifying the layers in a rock sequence.
That column constructed using the law of superposition.
To determine the age of an object.
relative dating
Relative dating is the process that places geologic events in the proper sequence.
Stratigraphic dating.
The geologic column is the result of the core sample showing layers of artifacts and material. Since some of these can be carbon dated, a relative time period can be established.
Absolute geologic age is determined through radiometric dating, and is the most precise method for determining the age of a rock or fossil within a small range. Relative geologic age is determined by the index fossils that may be contained within the rock that indicate a much broader range of possible ages based on the time the organism existed on Earth.

Geologists generally know the age of a rock by determining the age of the group of rocks, or formation, that it is found in. The age of formations is marked on a geologic calendar known as the geologic time scale. Development of the geologic time scale and dating of formations and rocks relies upon two fundamentally different ways of telling time: relative and absolute.
The geologic time scale.
By using the geologic time scale. Certain organisms are only found during certain times and if a fossil of one of these organisms is found then you can determine the relative age of the fossil.
Geologic column is an ordered arrangement of rock layers that is based on the relative age of the rocks. Geologic time is the time IN the geologic column.
Stratigraphic dating.
The geologic age of fossil organisms, rock, or geologic features or events defined relative of each other.
