One of these objects was mapped and named by Andrew Lawson. In the normal type of these boundaries, a graben [GRAH-buhn] is a downthrown block, and the hanging wall drops downward relative to the footwall. Up and down movement is associated with the dip-slip type of these features, some of which occur near the edges of tectonic plates. For 10 points, name these fractures i
