Tensional stress
Convergent on the western perimeter, divergent on the Easter perimeter.
It is called a divergent plate boundary.

divergent boundary
Stress at a divergent plate boundary is called tensional stress. This stress creates pulling forces that lead to the plates moving away from each other, resulting in the formation of new oceanic crust.
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.
Divergent boundary is formed
divergent boundary
It forms a convergent boundary with the South American Plate, divergent.
The mid-ocean ridge system is the longest continuous divergent plate boundary on Earth.
