Why is oceanic crust subducted under continental crust? A. Oceanic crust is moving faster than continental crust.
B. Oceanic crust is denser than continental crust.
C. Oceanic crust is less dense than continental crust.
D. Oceanic crust is older than continental crust.

B.) Oceanic crust is denser than continental crust.

Explanation:

Oceanic crust is denser, so it is subducted under the continental crust. The less dense magma then rises up through the continental crust, then it's further increasing the size of the continental crust and then maintaining it's lower density than the oceanic crust, which then causes subduction.

I hope this helped. I am sorry if you get this wrong.

it's false. hope i .
