The left side moves down while the right side moves up. A fault is a fracture in rock where there has been movement and displacement. Jump to: navigation, search. We know a fault exists only if it has produced an earthquake or it has left a recognizable mark on the earth’s surface. Faulting occurs when shear stress on a rock overcomes the forces which hold it together. Most faults produce repeated displacements over geologic This is what like when two cars crash into each other. n 1.

Cross-sectional illustration of normal and reverse dip-slip faults. Cross-sectional illustration of normal and reverse dip-slip faults. This movement may vary from a few centimetres to many kilometres depending on the nature and magnitude of the stresses and resistance offered by the rocks. The geological fractures occur at every scale, so that any large volume of rock has some or many. Faults may range in length from a few millimeters to thousands of kilometers. Here, sections of rock move past each other. Andrew Alden. Geological faults happen when stress occurs and determines the fault’s type after the event. Shear stressOccurs majorl… Once a fault has been identified, the next step is to determine how it behaves.

Fault, in geology, a planar or gently curved fracture in the rocks of Earth’s crust, where compressional or tensional forces cause relative displacement of the rocks on the opposite sides of the fracture.

A fault is a fracture or zone of fractures between two blocks of rock. Faults jpb, 2018. This sometimes makes earthquakes. When talking about earthquakes being along fault lines, a fault lies at the major boundaries between Earth's tectonic plates, in the crust, and the earthquakes result from the plates' movements. A fault is a fracture, or break, in the Earth's crust (lithosphere).
