WebA transform boundary, sometimes called a strike-slip or conservative boundary, is where the lithospheric plates slide past each other in the horizontal plane. This movement is described based on the perspective of an observer standing on one of the plates, looking across the boundary at the opposing plate. WebAt slip boundary condition the shear stress is taken as zero that means there is no existence of boundary layer formation at that plane. What are the examples of no-slip …
