Tension
It causes it to deform - this deformation is called "strain".
The movement in earths plates create powerful forces that pull or squeeze the rock in the crust.
Tectonic stress, caused by the movement of Earth's tectonic plates, produces the most significant crustal deformation. This stress results in the formation of features like mountains, faults, and earthquakes as the Earth's crust responds to the forces generated by tectonic plate interactions.
The earth's crust is not stress
Verticle stress causes monocline. Verticle stress causes monocline.
Compression Stress Tension Stress Shearing Stress
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.
Well, if you stress out a witch she will most likely put you under a spell that causes you to become physically ill ;)
Tension or tensile stress is what you described in the question.
A convergent boundary causes compressional stress.
Stress causes no sleep
which can cause a stress fracture
