Transform boundarys
these boundaries are were the plates will move toghether. or they will slide past eachother or they can move from eachother. which is why the earth has diffrent shapes in the earth. Also when the plates move away from eachother and then one slips past the other it causes an earth quake occurs . And heres a cool fact when the pacific plate and the north american plate moved together the formed the san Andreas fult line in california.
