Which of the following examples best illustrates the effects of ductile deformation?
-Rocks along a convergent plate boundary are subjected to gentle compressive force for millions of years, but once the compression ends, the rock returns to its original shape.
-Divergent boundaries will bend rocks through tension, but once the tension is over, the rock will return to its original shape.
Rocks are subjected to great pressure and fragment as a result.
-Rocks along a convergent plate boundary are subjected to compressive force for millions of years and are permanently folded.
-Divergent boundaries will bend rocks through tension, leaving a permanent fold.
