the geologic column is used for identifying the layers in a rock sequence.
a geologic time scale has eras, made up of periods, epochs, etc. hope this helps! :D
The geological column is an abstract, and ideal. What it really signifies is the mechanism of superposition, the fact that through geological times, newer layers are formed on top of older layers. The geological column can be used as a guide for reconstructing the geological history of a formation, but one should take care: geological processes, like all of nature, are messy, and geological strate can be inverted or skewed, so that newer strata may be beside or even below older strata. The inferred age of a geological stratum may be used to assist in dating fossils, and thereby aid in constructing histories for particular lineages. But in itself, this geological notion has little to do with biological evolution.

An ideal sequence of rock layers that contains all the known fossils and rock.
No. It only means that it is difficult to use that geological column to date that particular fossil which has managed to survive subsequent erosion of successive layers. Trees are generally quite long and because of this they may often be stretched through several layers.
In itself, it isn't. The geological column is a principle used in the preliminary dating of geological features relative to other features. Palaeontology uses estimates gained through geological dating to establish timeframes for the emergence of particular forms in the fossil record. These timeframes in themselves also aren't evidence for common descent, in themselves. What is evidence for common descent is that derived forms are almost always found in geological features that are younger than the layers the oldest basal forms are found in. For example: no primates before mammals; no apes before primates; no humans before apes; and so on.
Eon - Phanerozoic (most distant) Era - Cenozoic Period - Quaternary Epoch - Holocene (most recent)
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.
No, because there are natural event occuring at all times so even if there was a geoloogical column it would have eroded away or been distroyed
The first problem with the geological column is that it indicates occurs nowhere in the world.
No. It is cut into sedimentary rocks though. You'd need to look at a geological map, or least stratigraphical column, to know which ones.
