The answer is seafloor spreading. It is a progression that happens at mid-ocean ridges which are the divergent boundaries, where new oceanic crust is made through volcanic activity and then slowly moves away from the ridge. This helps clarify the continental drift theory in the plate tectonics theory.
I think the one that caused by pressure from a large-scale geological event is : A. Regional
Regional metamorphism covers a large area of continental crust including several mountain ranges and tectonic plates
hope this helps
soft clay and wet and sandy soil as they are more likely to collapse or corrode over time especially the wet and sandy soil which will erode with rain or water
What are all the options?
