This is simple but i want a for sure answer : ) 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.

C. Oceanic plate is thinner and denser than continental plate.

Explanation:

Oceanic plate is also called SIMA because it is made up of silicon and magnesium whereas continental plate is called SIAL because it is made up of silicon and aluminium. Oceanic plate and continental plate both are less dense that mantle but oceanic plate is denser than continental plate. Oceanic plate is made up of basaltic rocks and continental plate is made up of granitic rocks.
