The ocean floor is at a lower elevation than the continents. which of the following pieces of evidence best supports this claim? a)tectonic plates located below the continental crust do not move. b)gravitational force is stronger beneath the continental crust. c)oceanic crust is thinner and denser than continental crust. d)continental crust and oceanic crust are stacked in alternating layers.

The correct answer is option C, that is, oceanic crust is thinner and denser than continental crust.

Explanation:

The collision of two plates takes place with each other in the phenomenon of convergent plate tectonics. The heavier and denser plate gets sink underneath the lighter plate. When one plate bend and slides beneath the other, the heating of the plate takes place due to the presence of hot magma, the phenomenon is called subduction.  

Oceanic crust is denser in comparison to the continental crust. While undergoing subduction, the oceanic plate generally sinks below the mantle and produces a subduction zone.
