A rift valley forms at a divergent boundary. When plates diverge, the crust in between them is pulled thin. This tension creates a rift valley, such as the one found between the two islands of New Zealand. Over time, the stretched crust with grow so thin that rising magma will break its surface, forming an underwater ridge.
