Transform ones occur at plate boundaries.
Horsts and Grabens are regions formed by the action of these, and slow constant movement at these formations is called creep. Their line of action is their trace and fundamental ones penetrate the entire lithosphere. Movement in the horizontal plane occurs in strike-slip ones and a notable intraplate example is New Madrid (Mad-rid). Transform ones occur at plate boundaries. For 10 points, name these fractures in the Earth's crust that are often associated with earthquakes, like the San Andreas.
