Relative dating of the pennsylvanian period

As a start, let us examine more fully what Morris and Parker actually said about the geologic column: ‘The column is supposed to represent a vertical cross-section through the earth’s crust, with the most recently deposited (therefore youngest) rocks at the surface and the oldest, earliest rocks deposited on the crystalline “basement” rocks at the bottom.

If one wishes to check out this standard column (or standard geologic age system), where can he go to see it for himself? almost any textbook, in fact, that deals with evolution or earth history.

This standard column is supposed to be at least 100 miles [160 km] thick (some writers say up to 200 [320 km]), representing the total sedimentary activity of all of the geologic ages.

Relative time is the physical subdivision of the rocks found in the Earth's geology and the time and order of events they represent.

Absolute time is the measurement taken from the same rocks to determine the amount of time that has expired.

Relative time - named subdivisions of the Earth's geology in a specific order (for example, the "Cambrian Period", followed by the "Ordovician Period", and "Silurian Period").

Most of these subdivisions are recognized globally on the basis of their relative position in the Earth's stratigraphy and their fossil content.
