Idioms for fault

Origin of fault

synonym study for fault

1. Fault, failing, foible, weakness, vice imply shortcomings or imperfections in a person. Fault is the common word used to refer to any of the average shortcomings of a person; when it is used, condemnation is not necessarily implied: A quick temper is her greatest fault. Foible, failing, weakness all tend to excuse the person referred to. Of these foible is the mildest, suggesting a weak point that is slight and often amusing, manifesting itself in eccentricity rather than in wrongdoing: the foibles of artists. Weakness suggests that the person in question is unable to control a particular impulse, and gives way to self-indulgence: a weakness for pretty women. Failing is closely akin to fault, except that it is particularly applied to humanity at large, suggesting common, often venial, shortcomings: Procrastination and making excuses are common failings. Vice (which may also apply to a sin in itself, apart from a person: the vice of gambling ) is the strongest term, and designates a habit that is truly detrimental or evil.

Scientific definitions for fault

fault
[ fôlt ]

A fracture in a rock formation along which there has been movement of the blocks of rock on either side of the plane of fracture. Faults are caused by plate-tectonic forces. See more at normal fault reverse fault strike-slip fault thrust fault transform fault. See Note at earthquake.

A Closer Look

Bedrock, the solid rock just below the soil, is often cracked along surfaces known as planes. Cracks can extend up to hundreds of kilometers in length. When tensional and compressional stresses cause rocks separated by a crack to move past each other, the crack is known as a fault. Faults can be horizontal, vertical, or oblique. The movement can occur in the sudden jerks known as earthquakes. Normal faults, or tensional faults, occur when the rocks above the fault plane move down relative to the rocks below it, pulling the rocks apart. Where there is compression and folding, such as in mountainous regions, the rocks above the plane move upward relative to the rocks below the plane; these are called reverse faults. Strike-slip faults occur when shearing stress causes rocks on either side of the crack to slide parallel to the fault plane between them. Transform faults are strike-slip faults in which the crack is part of a boundary between two tectonic plates. A well-known example is the San Andreas Fault in California. Geologists use sightings of displaced outcroppings to infer the presence of faults, and they study faults to learn the history of the forces that have acted on rocks.
