Web27 mei 2024 · The plate tectonics theory has been widely accepted among scientists since the middle of the 20th century. There are four types of plate boundaries: divergent, convergent and transform boundaries, as well as the specific plate boundary zones that happen when the interactions between the plates are unclear. WebThe majority of mountain-building events, earthquake activity and active volcanism on the Earth’s surface can be attributed to tectonic plate movement at active margins.
