What types of stress are present at divergent plate boundaries?

Answer 1

divergent plate boundaries are associated with normal faulting. Thus there is a horizontal least compressive stress, vertical most compressive stress and a intermediate horizontal stress. All stresses are orthoganal to each other.

Answer 2

At divergent plate boundaries, the main types of stress are tensional and shear stresses. Tensional stress occurs as the plates move away from each other, leading to the stretching and thinning of the lithosphere. Shear stress occurs along transform faults, where plates slide past each other horizontally, causing friction and pressure to build up.

Answer 3

A divergent (plate) boundary undergoes a predominantly extensional stress regime with the direction of sigma 3 being in the directions of extension as shown here:

σ3 <----|ridge|----> σ3

Answer 4

A combination of tension from any subduction on the opposite side of the plate, and compression from the horizontal component of forces exerted by the mantle rock rising into the plate boundary. Also bending moments from the rising magma.

Answer 5

Tensional stress (pulling apart) is the stress that occurs at divergent plate boundaries.

Answer 6

Compressional stresses occur at convergent plate boundaries.

Answer 7

Divergent boundaries are under tensile stress.

Answer 8

A divergent plate boundary is an area where two plates are pulling away from each other. This creates stress or tension in the area, often making the area prone to earthquakes.

Answer 9

Tensile stress.

Answer 10

Compression
