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.
tension
The pulling force that causes tectonic plates to move apart, leading to the formation of new lithosphere, is called "tensional force." This force occurs at divergent boundaries, where plates are pushed apart due to mantle convection and the upwelling of magma. As the plates separate, magma rises to fill the gap, solidifying to create new crust.

The force of changing earth's crust is...... that the earth's crust is a lot thinner
When tectonic plates push the crust downward, the land feature that forms is called a "trough" or "rift." This process can create valleys or basins where the land is depressed between higher elevations. In some cases, this can also contribute to the formation of geological features like pull-apart basins or oceanic trenches.
Tension stretches or pulls apart the crust.
tension
Generally materials that fly apart are being pushed rather than pulled. We could devise a mechanism that pulls materials apart - for example, if we attach two hooks and pull them on winches in opposite directions. In that case we would describe the force as mechanical in nature. But it is more likely that things get pushed apart by their own internal pressure.
tension
Tensional stress force pulls on the crust and stretches rock. This type of stress occurs where tectonic plates are moving away from each other.
The force that pulls apart the crust is called tensional or extensional tectonic stress, which occurs at divergent plate boundaries where tectonic plates move away from each other. This pulling force can lead to the formation of rift valleys and mid-ocean ridges.
Tensile force / stress.
Tensile force stretches objects by pulling them apart along their length. This force is exerted when an external force is applied to stretch or elongate a material, causing its molecules to separate and create tension within the object.
The force that stretches a spring is called tension force. This force appears when the spring is being pulled or stretched in one direction.

Tension. The force itself is not elastic, but the material being pulled may be.
