Explanation:

Shear stress occurs in what we call transform boundaries. Transform boundaries happen when two tectonic plates slide against each other.

There are 3 main types of stress and shear stress is one of them.

Compression stress occurs when two tectonic plates are convergin g (at convergent boundaries).

Tension stress occurs when two tectonic plates are diverging, or when they are moving apart, (at divergent boundaries).
