Erosion
The arrows on a cutting plane line indicate the direction in which the section is viewed. They help clarify the orientation of the view, allowing the reader to understand how the object has been cut and what part of the interior is being displayed. This is essential for accurately interpreting the cross-section and the details within it.
A section line in drafting is a symbolic representation used to indicate where a cut or section through an object has been made to reveal its internal features. It typically appears as a dashed or solid line on a drawing, often labeled with a reference to the corresponding sectional view. Section lines help convey details that are not visible in external views, providing a clearer understanding of the object's structure and design.
A fence diagram is geologic cross section that allows easy visualization of the stratigraphic changes in subsurface conditions. The data used to create fence diagrams comes from soil samples or rock cores obtained from borings done by engineers or geoligists.
Two dots before a double bar in musical notation indicate a repeat sign. The first dot signifies that the musician should repeat the section of music from the beginning or from a previous repeat sign, and the double bar indicates the end of the section. This notation helps clarify the structure of the piece and provides guidance on how to perform it.
Page and section breaks are typically represented by horizontal lines in word processing software and document editors. These lines visually indicate the end of one section or page and the beginning of another, helping to organize content clearly. They serve as a guide for both the writer and the reader, enhancing the overall readability of the document. In some applications, these lines may be more pronounced or styled differently to differentiate between types of breaks.
A dis-conformity is an unconformity representing a period of erosion or lack of deposition in a sedimentary rock section.
When layers of rock are missing from a sequence, this is referred to as a "unconformity." An unconformity indicates a gap in the geologic record, often caused by erosion or non-deposition of sediment over a period of time. This missing section can provide important insights into the geological history and processes that have shaped the area. Types of unconformities include angular unconformities, disconformities, and nonconformities.
The symbol used in music to indicate a repeat of a section is called a "repeat sign."
Section Z happened in 1985.
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.
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.

The four large sections on the geologic time scale are eons, eras, periods, and epochs. Each of these divisions represents a different scale of time with eons being the largest and epochs being the smallest.
Contour maps are used to show the below ground surface of geologic strata, fault surfaces (especially low angle thrust faults) and unconformities. Isopach maps use isopachs (lines of equal thickness) to illustrate variations in thickness of geologic units.
