What fault occurs when tectonic plates pull apart from one another and tensional stress is placed on rock layers?
normal fault occurs...odyssey
Which way do rocks move in a fault?
A fault zone is created when directed stress (as opposed to isotropic stress that simply compacts materials) overcomes the physical strength of the rock to withstand pressure leading to a pervasive crack. If the stress that created the fault is pulling the rock apart, the block that lies above the fault (the hanging wall) is bound to sink and the rocks below the fault will move upwards relative to the hanging wall. This situation is termed a "normal fault" and occurs for example in rift zones all over the world. If confining pressure produces a fault, the hanging wall is pushed on top of the rocks below the fault. This is known as a "reverse fault" and is a common phenomenon in many mountain ranges. In a special type of stress regime, faults are created along which rocks are sliding past each other horizontally. They are called "transform faults".
When the rock above the fault surface moves down relative to the Rock below the fault surface what kind of fault?
This is described as a normal fault.
What fault moves rock downward?
a normal fault
The land between two normal faults may be uplifted to form?
Normal Faultin a normal fault, the hanging wall slips down relative to the footwallfootwall- the rock that lies belowhanging wall- the block of rock that lies abovenormal fault- tension in Earth's crust pulls rock apart which causes normal fault2. The Land Between Two Normal Faults Moves Upward To Form What?is a Fault - Block Mountain.
In which type of fault are rock slabs being pulled apart?
a normal fault
What kind of fault forms when rock is pulled apart?
A normal fault would form.
What kind of rock forms when rock is pulled apart?
A normal fault would form.
What fault causes rocks to become twisted and strained?
A Transform fault where one tectonic plate slides past another tectonic plate results with rocks being pulled apart. Slippage results when the rock of one plate bends the rock of another, causing elastic rebounds and the release of energy as surface waves.
What type of stress occurs when layers of rock are pulled apart?
It is the SHEAR.
What type of fault is formed when plates diverge or apart?
Tension in Earth's crust pulls rock apart, causing hanging walls. In a normal fault, the fault is at an angle, so one block of rock lies above the fault while the other block lies below the fault. The block of rock that lies above is called the hanging wall. The rock that lies below is called the footwall.

The block of rock that lies above is called the hanging wall. The rock that lies below is called the footwall.
What is a normal fault zone?
In many cases a fault does not consist of a single crack but of a series of cracks in the rock that all form close to the same plane. A normal fault is a fault tat forms as a result of two blocks of rock being pulled away from one another, with one block sliding down the fault.

How does a fault line work?
A fault line works by two MASSIVE pieces of rock with a crack in between them. when they grind together or push apart, a earthquake is formed.
What is a normal fault?
That the hanging wall is moved downward. They occur were two blocks of rock pull apart, by tension.
What happens when the pressure snaps the rock?
A "fault plane is created, rock layers move relative to one another (rock can melt in the fault plane forming Pseudotachylyte or Mylonite) and energy is released as an earthquake.
