Plate tectonics, the movement of the large pieces of the earth's crust, give rise to great stress along the boundaries of the plates. Wikipedia has a post on plate tectonics, and a link is provided.
The earth's crust is not stress
The sudden vibration in the plates inside the crust causes the earths crust to rise & fall.
A divergent boundary causes tensional stress, where tectonic plates are moving away from each other. This stress results in the stretching and thinning of the Earth's crust, leading to the formation of new crust through volcanic activity and seafloor spreading.
The famous break in the Earth's crust that causes earthquakes to occur is called a fault line. Movement along fault lines can result in earthquakes due to the build-up and release of stress between tectonic plates.
continental crust
The movement in earths plates create powerful forces that pull or squeeze the rock in the crust.
Tension
It causes it to deform - this deformation is called "strain".

Pressure from the earths core
Compression Stress Tension Stress Shearing Stress
it means earthquakes will happen more often
Mining?
mining ;)
It can be the cause of folding, faulting, mountains, volcanoes, earthquakes, and rifts.
It stresses it and causes cracks.
