Question

3 multiple choice 1 point
there are 2 types of crust, continental and oceanic. when the 2 types of crust are pushed into each other, the oceanic crust always sinks below the continental crust because:
the ocean is pushing down on the oceanic crust
both the continental and oceanic crust are the same density
the continental crust is more dense than the oceanic crust
the continental crust is less dense compared to the oceanic crust

Explanation:

Oceanic crust is denser than continental crust (composed of heavier basaltic rock vs lighter granitic rock for continental crust). When two crust types collide, the denser one sinks below the less dense one.

Answer:

the continental crust is less dense compared to the oceanic crust
