Stress that acts to pull materials (including rocks of the crust) apart is known as tensile stress.

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.
The stress force that pulls on the crust and thins rock in the middle is called tension. Tensional stress occurs when two plates move away from each other, creating faults where rocks are pulled apart and thinned in the middle. This process is often associated with the formation of rift valleys and mid-ocean ridges.
The tension that pulls rocks apart is known as extensional stress. This type of stress occurs in tectonic settings where tectonic plates are moving away from each other, such as at divergent boundaries. As the rocks are pulled apart, they can create features like rift valleys or mid-ocean ridges, leading to volcanic activity and the formation of new crust.
Tension stress is the type of stress that pulls and stretches the rock of the Earth's crust. It commonly occurs at divergent plate boundaries where tectonic plates are moving away from each other. This stress can lead to the formation of features like rift valleys and mid-ocean ridges.
Tensile stress.
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.
The force that tends to pull rocks apart is called tensional stress. This stress occurs when rocks are being stretched in opposite directions, causing them to break and create faults or fractures in the Earth's crust.
When rocks change shape due to stress, the process is called "deformation." This can occur through mechanisms such as bending, breaking, or flowing, depending on the type and amount of stress applied. Deformation can lead to geological features like folds and faults in the Earth's crust.
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.
Cracks in the Earth's crust, known as faults, result from various stresses, primarily tectonic forces. These forces include tensile stress, which stretches the crust, compressional stress, which pushes rocks together, and shear stress, which causes rocks to slide past one another. When the accumulated stress exceeds the strength of the rocks, they break, leading to fractures or faults. This process is often associated with seismic activity, as the release of stress can trigger earthquakes.
