At which type of boundary is new oceanic crust created?
网页2021年11月26日 · New oceanic crust is created at divergent plate boundaries. New oceanic crust is created at a divergent plate boundary. This type of boundary is characterized by two tectonic plates moving apart from one another. As they separate, magma from the mantle rises to fill the gap, cools, and solidifies to form new crust.

what happens when oceanic crust collides with continental crust at …
网页2020年3月3日 · Answer. Answer: The oceanic crust is known to be more dense than the continental crust. When a plate carrying an oceanic crust collides with a plate carrying continental crust, the plate carrying continental crust becomes unable to sink under the more dense plate of oceanic crust. As a result, the plate of continental crust sinks beneath the ...
