The guidelines used to determine the relative ages of the rocks and events shown by a geologic cross-section is the Law of Superposition. It is the basic law of geochronology.

What do the relative geologic time and absolute geologic time combine to form?

The geologic time scale.


Diffrenciate geologic time with geologic column?

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.


What is the definition of relative age?

The geologic age of fossil organisms, rock, or geologic features or events defined relative of each other.


How can fossils be used to determine the relative ages of rock?

If we know the age the respective organism is known to have occupied a certain region in the geologic past we can then correlate that to the rock its fossil was found in and consequently deduce the rock's relative age.


What type of dating would be used to determine the age of rocks by using the fossil?

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.


What are three types of clues to the relative age of rock layers other than the law of superposition?

To determine relative age, geologists also study extrusions and intrusions of igneous rock, faults, gaps in the geologic record, and inclusions.


How can the principles of stratigraphy be used to do relative age dating?

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.


How does relative dating show the geologic history of a region?

how does relative dating show the history of a region


How is the geologic used in relative 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.


The process that places geologic events in proper time sequence is referred to as?

relative dating


How is The geologic column using relative 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.
