This often produces a mid-ocean ridge, where magma welling up from deep below reaches the sea bed and solidifies.
Tensile stress occurs when members are pulled apart, causing tension within the material. This type of stress occurs when forces act to stretch or elongate the material, potentially leading to deformation or fracture.
Plate tectonics. Sub layers called tectonic plates lie underneath continents move, shift, and grind against or away from each other. The actual process of pulling apart is called diverging. The super-continent Pangaea is an example of a continent that was pulled apart. First it was pulled apart into two continents that are called Laurasia and Gondwana and then was pulled farther apart into the world that we see today.
The primary forces that act on rocks in Earth's crust are compression and tension. Compression occurs when rocks are squeezed together, often leading to folding and faulting. Tension is when rocks are pulled apart, creating fractures and rifts. These forces are generated by tectonic plate movements and can result in various geological features.
When members are pulled apart, it typically refers to a type of force known as tensile stress. This occurs when a material or structure is subjected to forces that attempt to stretch or elongate it. In engineering and physics, this can lead to structural failure if the material exceeds its tensile strength. Understanding tensile stress is crucial in designing safe and effective structures.
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.

Geologists call the process of tectonic plates breaking apart "rifting." It occurs when the Earth's lithosphere is being pulled apart, causing the plates to separate, creating new ocean basins. Rifting is a key stage in the formation of new tectonic boundaries.
A rift valley.
The force that pulls an object apart is called tension. Tension occurs when a material is stretched or pulled in opposite directions, causing it to become elongated.

Yes. Tectonic plates are extremely strong and catastrophic in some cases.

A fault called a normal fault occurs when tectonic plates pull apart and tensional stress causes the rock layers to break and move along the fault line. In a normal fault, the hanging wall moves down relative to the footwall due to the extensional forces acting on the rocks.
Rifting is a geological process in which the Earth's lithosphere is pulled apart, leading to the formation of a rift valley. This occurs due to tectonic forces that create tension, causing the crust to thin and fracture. As the rift develops, magma from the mantle may rise to fill the gaps, potentially leading to volcanic activity. Over time, the rift can evolve into a new ocean basin if it continues to widen.
Four internal forces include tension, compression, shear, and torsion. Tension occurs when a material is pulled apart, compression when it is pushed together, shear when it is twisted in opposite directions, and torsion when it is twisted along its axis.
