Most tectonic plates move apart at mid-ocean ridges, which are underwater mountain ranges formed by volcanic activity. At these divergent boundaries, magma rises from the mantle to create new oceanic crust as the plates separate. This process leads to the formation of new seafloor and is a key driver of plate tectonics. Additionally, rift valleys can occur on land where continental plates are diverging.
