When continental and oceanic plates gather, the fact try a foreseeable you to
Simply because of its greater occurrence, the brand new oceanic dish effortlessly subducts below the side of the latest continental plate. Again subduction of your own oceanic dish contributes to volcano formation, but in this means, the newest strings from volcanoes versions to your continental crust. That it volcanic hill strings, labeled as an eruptive arch, is oftentimes multiple hundred miles inland from the dish erica and you may the brand new Cascade Slopes away from America is actually examples of volcanic arcs formed by the subduction along a great continental-oceanic convergent margin. Continental-oceanic convergence may mode a favorite trench, although not constantly. Zero continental-oceanic divergent margins are present today. Obviously, they are impractical to create and you may would quickly become oceanic-oceanic divergent margins since ocean flooring spreading took place.
Alter margins
Together with convergence and you can divergence, changes activity may possibly occur together plate margins. Continua a leggere
