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.

∙ 9y agoThe Principle of Cross-Cutting Relationships is a good guideline to know the estimated age of rocks and events. This states that the formation of rocks that cuts across rocks must be younger than the rocks that they cut across.

What is the difference between a topographic profile and a geologic cross section?
A topographic profile is a plot showing the shape of the surface of the ground (so hills, hillocks, dips, valleys and the like). Whereas a geologic cross section shows the order and structure of soils and / or rocks below the ground surface. Geologic sections are typically created by first drawing a topographic profile of the section of interest then adding in the underlying strata. An example of the way they are created is given in the related links.
A gap in the geologic record formed when sedimentary rocks cover an eroded surface is called an?
A dis-conformity is an unconformity representing a period of erosion or lack of deposition in a sedimentary rock section.
How can you determine the relative age of a rock layer by looking at a cross section?
In the cross section, examine the different layers. The layer at the very bottom will be the oldest, and the one above would be slightly newer, and the one above that even newer, and so on, until the most recent rock layer is found at the top. Therefore, the layer you study will depend on those features. If you know the age of one layer, you will know the relative age of another.
What is a geologic cross section?
Taken along a line drawn on a map, it is a diagram of the structure and position of the rock layers present beneath the surface along this line. Geologists learn how to construct this 3rd dimensional information from a Geologic map, If you want to know how to get at an ore body hidden underground, you need a Geologist to work out where and how deep to dig. Cross sections will be needed to do this.
