Most geological activity takes place at plate boundaries. Webb6 maj 2024 · The continental drift hypothesis was developed in the early part of the 20 th century, mostly by Alfred Wegener. Wegener said that continents move around on Earth’s surface and that they were once joined together as a single supercontinent. While Wegener was alive, scientists did not believe that the continents could move. WebbMost movement occurs along narrow zones between plates where the results of plate-tectonic forces are most evident. There are four types of plate boundaries: Divergent boundaries -- where new crust is generated as the plates pull away from each other. Convergent boundaries -- where crust is destroyed as one plate dives under another. gabin korean restaurant scarborough
