Mechanical Cross Section | Semitracks

Mechanical cross sectioning, although not as accurate or easy to perform as focused ion beam cross sectioning, is relatively inexpensive to perform. A good cross sectioning wheel and the necessary supplies cost less than $10k. A bad cross section is worse than no cross section at all, since the process is destructive.

Constructing a topographic profile - SERC

In introductory geoscience courses, a profile is appropriate when you are asked to construct a cross-section or profile. Topographic profiles are used to understand what a topographic map is telling you in a specific area (or, you can think about it like it is giving you a "side view" of the landscape along a specific line on the map).
