Explanation / Answer

1. d All boundary tyoes.

Divergent Plate Boundaries: Divergent plate boundaries are locations where plates are moving away from one another. This occurs above rising convection currents.

Convergent Plate Boundaries: Convergent plate boundaries are locations where lithospheric plates are moving towards one another. The plate collisions that occur in these areas can produce earthquakes, volcanic activity and crustal deformation.

Transform Boundary: Transform Plate Boundaries are locations where two plates slide past one another. The fracture zone that forms a transform plate boundary is known as a transform fault. Most transform faults are found in the ocean basin and connect offsets in the mid-ocean ridges.
