What process involves the comparison of rock layers with others in a sequence to determine its age?
relative dating
Why is it necessary to observe the rock layers of several different localities in order to obtain a complete sequence of events?

What is the geologic columnused in relative dating?
1.Geologists use the geologic column to help them interperet rocks sequences. 2.they use to help them identify rock layers in complicated rock sequence.

When a layer or several layers of rock are missing from a rock layer sequence this is called a what?
It is called an uncomformity.

How do a geologist use the principle of superposition?
A geologist uses the principle of superposition to determine the relative ages of rocks and sedimentary layers. This principle states that in undisturbed layers of rock, the youngest layers are at the top while the oldest layers are at the bottom. By observing the order in which different rock layers are stacked, a geologist can infer the sequence of events that happened over time in a particular location.

What is a geologic column?
An ideal sequence of rock layers that contains all the known fossils and rock.

How do you determine the order of rock layers?
The chronological order of rock layers is usually determined by their order in an undisturbed sequence of strata. According to the principle of superposition, the oldest layers would be found at the bottom and the youngest layers at the top. In disturbed rock layers (those that have been folded, uplifted, or generally disrupted by tectonic forces), the determination must be made based on the presence of index fossils, comparison to undisturbed strata or radiometric dating.
What is geological column used for?
the geologic column is used for identifying the layers in a rock sequence.
What rock layer is the youngest?
The principle of superposition states that in an undisturbed sequence of rock layers, the youngest will be at the top, the oldest at the bottom.
What determines the sequence of events in the rock cycle?
weather the rock is weather, eroded, or goes through deposition.
