FAQ: In Which Of The Following Faults Does The Hanging Wall Move Down Relative To The Footwall?

Which fault will see the hanging wall move down relative to the footwall?

If the hanging wall moves down relative to the footwall, the fault is a normal fault. Normal faults are caused by tensional stress, or stress that pulls rocks apart..

What type of fault occurs when the hanging wall moves up relative to the footwall quizlet?

Terms in this set (11)

2) Reverse Fault– if the hanging wall moves up relative to the footwall, the fault is called a reverse fault.

Which fault will see the hanging wall?

The two sides of a non-vertical fault are known as the hanging wall and footwall. The hanging wall occurs above the fault plane and the footwall occurs below it.

Which of the following types of faults will form when the hanging wall move up?

Reverse faults form when the hanging wall moves up. The forces creating reverse faults are compressional, pushing the sides together. Transcurrent or Strike-slip faults have walls that move sideways, not up or down.

What is the difference between footwall and hanging wall?

The FOOT WALL BLOCK is the block which would be under the feet of a person standing in a tunnel on the fault plane. The HANGING WALL BLOCK would then be hanging overhead. The UPTHROWN SIDE of the fault is the side on which the movement has been up relative to the other side.

What are the three types of faults?

Different types of faults include: normal (extensional) faults; reverse or thrust (compressional) faults; and strike-slip (shearing) faults.

When a fault is expressed at the surface it is called a quizlet?

When a fault is expressed at the surface, it is called a. fault scarp. The name of the site where slippage begins and earthquake waves radiate outward is called the. hypocenter.

What type of stress causes fault to form?

In terms of faulting, compressive stress produces reverse faults, tensional stress produces normal faults, and shear stress produces transform faults. *Terminology alert: Geoscientists refer to faults that are formed by shearing as transform faults in the ocean, and as strike-slip faults on continents.

What force causes folding?

1. Figure 10.9: Folds are a result of ductile deformation of rocks in response to external forces. 2. Layered rocks folded into arches are called anticlines whereas troughs are referred to as synclines.

How do you identify a normal fault?

If the hanging wall drops relative to the footwall, you have a normal fault. Normal faults occur in areas undergoing extension (stretching). If you imagine undoing the motion of a normal fault, you will undo the stretching and thus shorten the horizontal distance between two points on either side of the fault.

Is a normal fault caused by compression?

Normal dip-slip faults are produced by vertical compression as Earth’s crust lengthens. The hanging wall slides down relative to the footwall. Normal faults are common; they bound many of the mountain ranges of the world and many of the rift valleys found along spreading margins…

What are the four types of faults?

There are four types of faulting — normal, reverse, strike-slip, and oblique. A normal fault is one in which the rocks above the fault plane, or hanging wall, move down relative to the rocks below the fault plane, or footwall.

What type of movement does a normal fault have?

normal fault – a dip-slip fault in which the block above the fault has moved downward relative to the block below. This type of faulting occurs in response to extension and is often observed in the Western United States Basin and Range Province and along oceanic ridge systems.

What is the most dangerous type of fault?

Reverse faults, particularly those along convergent plate boundaries are associated with the most powerful earthquakes, megathrust earthquakes, including almost all of those of magnitude 8 or more. Strike-slip faults, particularly continental transforms, can produce major earthquakes up to about magnitude 8.

What is an example of a normal fault?

A normal fault is a fault in which the hanging wall moves down relative to the footwall. An example of a normal fault is the infamous San Andreas Fault in California. The opposite is a reverse fault, in which the hanging wall moves up instead of down. A normal fault is a result of the earth’s crust spreading apart.
