In isometric projection, the most commonly used form of axonometric projection in engineering drawing, [4] the direction of viewing is such that the three axes of space appear equally foreshortened, and there is a common angle of 120° between them. As the distortion caused by foreshortening is uniform, the proportionality between lengths is ...
This is a list of free and open-source software for geological data handling and interpretation. The list is split into broad categories, depending on the intended use of the software and its scope of functionality. Notice that 'free and open-source' requires that the source code is available and users are given a free software license.
Types of faulting. Anderson's theory of faulting, devised by Ernest Masson Anderson in 1905, is a way of classifying geological faults by use of principal stress. [1] [2] A fault is a fracture in the surface of the Earth that occurs when rocks break under extreme stress. [3]
Simplified model of oblique subduction. The oblique subduction motion is composed of motion vectors that are parallel and orthogonal to plate boundary. [1] The obliquity of plate convergence is compensated by the relative motion between forearc sliver and the remaining overriding plate. [1]

This is a starting point for collating free, web-based resources available to editors, as well as indexes to help point to sources. Please feel free to add new resources with a URL to the site, and a brief description. Don't worry too much about presentation or organization, this is just a draft. Add new headings as needed.
A fault scarp is a small step-like offset of the ground surface in which one side of a fault has shifted vertically in relation to the other. [1] [2] The topographic expression of fault scarps results from the differential erosion of rocks of contrasting resistance and the displacement of land surface by movement along the fault.
A skew arch (also known as an oblique arch) is a method of construction that enables an arch bridge to span an obstacle at some angle other than a right angle. This results in the faces of the arch not being perpendicular to its abutments and its plan view being a parallelogram , rather than the rectangle that is the plan view of a regular, or ...
