They are caused primarily by shear stress.

Tensional forces normally cause what?
Tensional forces typically cause an object to stretch or elongate. These forces act in opposite directions along an object and can result in deformation or breakage if they exceed the object's strength.
What is three types of faults include a strike-slip fault a what fault and a reverse fault?
Three types of faults include: Strike-slip fault: horizontal movements along the fault line Normal fault: caused by tensional forces, with the hanging wall moving down relative to the footwall Reverse fault: caused by compressional forces, with the hanging wall moving up relative to the footwall
Is a fault block mountain caused by tension or compression?
A fault-block mountain is typically formed by tensional forces where blocks of the Earth's crust move vertically due to normal faults. These mountains result from the crust being pulled apart, leading to the uplift of fault blocks.
What are the two type of faults can result mountains and why?
The two types of faults that can result in mountains are thrust faults and normal faults. Thrust faults occur when older rock is pushed on top of younger rock, causing uplift and mountain formation. Normal faults occur when tensional forces cause one block of rock to drop down relative to another block, creating valleys and mountain ranges.
What type faults create mountain and valleys?
Mountain ranges are typically formed by compressional or convergent boundaries, where tectonic plates collide and cause uplift and folding of the crust. Valleys, on the other hand, can be created by various types of faults and processes, such as normal faults (resulting from tensional forces), erosion by rivers or glaciers, or subsidence of the crust.
Tensional forces normally cause which one of the following?
Tensional forces typically cause objects to stretch or elongate.
Are both normal and reverse faults caused by tension?
Normal faults are caused by tensional forces pulling rocks apart, leading to the hanging wall moving down relative to the footwall. Reverse faults are caused by compressional forces pushing rocks together, leading to the hanging wall moving up relative to the footwall.
Tensional forces normally cause what?
Tensional forces typically cause an object to stretch or elongate. These forces act in opposite directions along an object and can result in deformation or breakage if they exceed the object's strength.
What type of force caused normal fault to form?
tensional forces
Tensional forces cause what kind of fault?
In the extreme tension forces can cause local vulcanism. At a local level it may create fault block mountains. Over larger landscapes, it creates Rift Valleys such as the giant one in East Africa today.
What are normal faults caused by?
Normal faults are caused by tensional stress, which occurs when the Earth's crust is being pulled apart. This causes the hanging wall to move downward relative to the footwall, resulting in the formation of a normal fault.
What is three types of faults include a strike-slip fault a what fault and a reverse fault?
Three types of faults include: Strike-slip fault: horizontal movements along the fault line Normal fault: caused by tensional forces, with the hanging wall moving down relative to the footwall Reverse fault: caused by compressional forces, with the hanging wall moving up relative to the footwall
What fault is a product of horizontally directed tensional stresses?
Normal Faults
Are reverse faults rock layers placed under tensional stress?
No, reverse faults occur in response to compressional stress, not tensional stress. In a reverse fault, the hanging wall moves up relative to the footwall due to compression forces pushing the rocks together.
Are strike-slip faults caused by tension forces?
No, strike-slip faults are typically caused by horizontal shearing forces where blocks of the Earth's crust move past each other horizontally. Tension forces usually manifest in normal faults where blocks of the crust move away from each other, causing extension.
How are tensional forces created and what role do they play in the mechanics of structures?
Tensional forces are created when a structure is pulled or stretched in opposite directions. These forces play a crucial role in the mechanics of structures by helping to distribute loads and maintain stability. In essence, tensional forces help to counteract compressive forces and prevent the structure from collapsing under pressure.
What type of faults accomadate extension of the Earth's crust?
Normal faults accommodate extension of Earth's crust through the hanging wall moving downward relative to the footwall. The hanging wall is pulled down due to tensional forces, resulting in the crust being stretched and thinned.
