Cross slip can occur in both the edge dislocation as well as in screw dislocation.

Cross slip can occur in both the edge dislocation as well as in screw dislocation. Correct Answer False

The phenomenon of cross slip is restricted to screw dislocations. Since the line of screw dislocation and its Burgers vector are parallel, this does not define a specific plane as with an edge dislocation (where b is perpendicular to the dislocation line). So, in edge dislocation, cross slip is not possible.
