Tensional forces and compressional forces.
1) compressional forces 2) tensional forces 3) folding
They are caused primarily by shear stress.
The forces that causes rock layers to move are; 1. Tensional Force. 2. Compressional Force. 3. Quiescent Force.
There are three main forces that drive deformation within the Earth. These forces create stress, and they act to change the shape and/or volume of a material. The following diagrams show the three main types of stress: compressional, tensional, and shear. Stress causes the build up of strain, which causes the deformation of rocks and the Earth's crust. Compressional stresses cause a rock to shorten. Tensional stresses cause a rock to elongate, or pull apart. Shearstresses causes rocks to slip past each other.

Convergent plates move towards each other, causing alot of compressional forces. Divergent plates move away from each other causing alot of tensional forces.

Folded mountains form when two plates move towards each other by compressional forces. The movement results in sedimentary rocks moving upwards to form a series of folds.

The type of forces that dominate at convergent plate margins are compressive forces. The tensional forces are tectonic forces that tend to push two sides of body in opposite directions so that they slide horizontally past one another.
