What are the 3 types of stress in science?

The three main types of stress are typical of the three types of plate boundaries: compression at convergent boundaries, tension at divergent boundaries, and shear at transform boundaries. Where rocks deform plastically, they tend to fold. Brittle deformation brings about fractures and faults.

What is stress and strain?

Stress is defined as the force experienced by the object which causes a change in the object while a strain is defined as the change in the shape of an object when stress is applied. Stress is measurable and has a unit while a strain is a dimensionless quantity and has no unit.

A prime example of tensional stress is the mid-Atlantic ridge, where the plates carrying North and South America are moving west, while the plates carrying Africa and Eurasia are moving east. Tensional stress can also occur well within an existing plate, if an existing plate begins to split itself into two pieces.

What is compressional stress?

The stress that squeezes something. It is the stress component perpendicular to a given surface, such as a fault plane, that results from forces applied perpendicular to the surface or from remote forces transmitted through the surrounding rock.
