In transform boundaries, __ can build as plates slide, and suddenly release in an earthquake
What is tension?
True or false - the inward pulling of the crust can lead to the formation of a divergent boundary
False - divergent boundaries are caused by the tension and stretching of the crust can lead to the formation of a divergent boundary
