This is known as a normal fault.
A fault that forms at a divergent boundary
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.
Tensional stress from divergent plate boundaries causes a normal fault to form. This stress pulls rocks apart along a fault line, causing the hanging wall to drop relative to the footwall.
Fault, crack, fracture, fissure, joint are all terms that could be applied to this question.In structural terms, tensile stress in the earth's crust initially creates normal faults. If the tensile stress state persists, larger scale structures such as horst and graben will develop (where graben are down thrown blocks of crust surrounded by normal faults, horsts are the upthrown crustal blocks surrounding the graben).Ultimately this may result in the formation of a rift valley and or the creation of a divergent tectonic plate boundary.
Compression causes rocks to be pushed together, leading to folding and faulting in the crust, often resulting in mountain building. Tension, on the other hand, causes rocks to be pulled apart, resulting in the formation of rift valleys and normal faulting. Both compression and tension are important in shaping the Earth's crust and can lead to the formation of various geological features.
Tension stretches or pulls apart the crust.

Tensile stress.
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.
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.

A crack is caused by tension not compression because tension pulls matter apart while compression pushes matter together
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.
Tensile stress is the result of a force acting over a cross sectional area that pulls material apart. This occurs in normal faults, rift valleys and at divergent plate boundaries.
