What does fault mean in science?
fracture
A fault is a fracture or zone of fractures between two blocks of rock. Faults allow the blocks to move relative to each other. This movement may occur rapidly, in the form of an earthquake – or may occur slowly, in the form of creep. Faults may range in length from a few millimeters to thousands of kilometers.
What is an example of a fault in science?
Well-known terrestrial examples include the San Andreas Fault, which, during the San Francisco earthquake of 1906, had a maximum movement of 6 metres (20 feet), and the Anatolian Fault, which, during the İzmit earthquake of 1999, moved more than 2.5 metres (8.1 feet).
What is a fault in biology?
Anything that fails, that is wanting, or that impairs excellence; a failing; a defect; a blemish. As patches set upon a little breach Discredit more in hiding of the fault. ( Shak)
What are the three types of fault in science?
Different types of faults include: normal (extensional) faults; reverse or thrust (compressional) faults; and strike-slip (shearing) faults.
What are faults in tectonic plates?
Faults are cracks in the earth’s crust along which there is movement. These can be massive (the boundaries between the tectonic plates themselves) or very small. If tension builds up along a fault and then is suddenly released, the result is an earthquake.
What causes faults in the earth?
A fault is formed in the Earth’s crust as a brittle response to stress. Generally, the movement of the tectonic plates provides the stress, and rocks at the surface break in response to this. Faults have no particular length scale.

How do faults form?
It forms when rock above an inclined fracture plane moves downward, sliding along the rock on the other side of the fracture. Normal faults are often found along divergent plate boundaries, such as under the ocean where new crust is forming. Long, deep valleys can also be the result of normal faulting.

What is the cause of fault?
Faults are generally caused under the influence of stresses acting upon the rocks of the crust of the earth from within. Any rock on or below the crust may withstand all the operating stresses up to a limit, which depends upon its cohesive strength and internal friction.

Why do earthquakes occur at faults?
Earthquakes occur along faults, which are fractures between blocks of rock that allow the blocks to move relative to one another. Faults are caused by the bumping and sliding that plates do and are more common near the edges of the plates.

Where do faults occur?
Faults are fractures in Earth’s crust where movement has occurred. Sometimes faults move when energy is released from a sudden slip of the rocks on either side. Most earthquakes occur along plate boundaries, but they can also happen in the middle of plates along intraplate fault zones.
