Depending on the scale and also on the pressure temperature conditions where the extension is occuring there are a number of diffrent results of tension in rocks. At higher temperatures and pressures a type of ductile deformation occurs which can form structures by boudinage which causes the stretching and breakup of preexisting structures wihin the rock (see the related link for more information) to form a sausage or barrel geometry.
At shallower depths where materials behave in a brittle way, initially rocks will break "or crack" forming joints. If the tensile force continues to be applied and if it is large enough this may then generate normal faults and "horst and graben" structures. These are blocks of crust that are bounded by normal faults where the "graben" are downthrown blocks relative to the "horst", where this motion helps to accomadate the strecthing of the crust. See the realted links for more information and diagrams on this phenomenon.
If the crust continues to experience tensile stress at a high enough level for a long enough time, then ultimately a rift valley marking the creation of a new ocean and a new plate boundary will form.
What else can I help you with?
How does shearing affect rock in Earth's crust?
Shearing affects the rocks in the earth's crust when the rocks are being pulled apart in opposite horizontal directions
What happens to sediments as they move around?
The rocks will gradually get smaller
What happens before rocks give way in an earthquake?
pressure builds under the plates
What happens to the temperature of the rocks as layers go deeper into the Earth?
it gets hotter and the presure get harder
What is the natural wearing down or breaking apart of rocks?
physical
Is the forces that pulls rocks apart?
tension
Tension pulls rocks apart and creates this kind of fault?
Tension creates normal faults, where the hanging wall moves downward relative to the footwall. This type of fault is common in divergent boundary settings when tectonic plates move away from each other, causing extension and the rocks to be pulled apart.
What is stress that pulls on the rocks of the crust called?
Stress that acts to pull materials (including rocks of the crust) apart is known as tensile stress.
What type of stress pulls rocks apart?
Tension stress pulls rocks apart, causing them to stretch and potentially break along fractures or faults. This type of stress is common in divergent plate boundaries and areas experiencing extensional tectonic forces.
What is the Stress force that pulls rock apart?
Tensile stress is the force that pulls rock apart, causing it to break or fracture. This type of stress occurs when rocks are stretched in opposite directions, leading to the formation of cracks or faults in the rock.
What is the force that pulls rock apart?
Tensile stress.
What happens first rocks break apart or water fills tiny cracks in rocks and freezes or ice pushes against rocks?
All rocks have cracks in them. If water fills the cracks and freezes, it expands and pushes the rock apart.
What stress causes rocks to pull apart?
Tensional stress causes rocks to pull apart. This type of stress occurs when rocks are being pulled in opposite directions, leading to the stretching and extension of the rock mass. Over time, this can lead to the formation of faults and fractures in the rocks.
What process can break rocks apart?
erosion can break rocks apart, weathering can also break rocks apart
What are pushes or pulls on rocks?
us
What is the force that stretches or pull apart the crust called?
When there is a divergent boundary, regardless if the plates are ocean-ocean or continental-continental, tensional stress pulls on the crust. Rocks have weaker tensional strength than compressive strength, so they are easier to pull apart.
What happens to rocks when they undergo stress?
When the tension (stress) is great enough, they will fracture or deform.
