Question

Quizplus · Accepted Answer

Grabens and horsts are associated with the formation of rift valleys, which occur when tectonic plates move apart and create a divergent boundary. This is known as rift activity, making option B the correct choice.  Volcanic activity is associated with the presence of volcanoes, which may or may not be present in regions with grabens and horsts. Collision activity involves the convergence of tectonic plates, which is not associated with the formation of grabens and horsts. Strike-slip activity involves horizontal motion along a fault, while transform faulting involves movement along a transform boundary. Neither of these are directly associated with the formation of grabens and horsts.
