A) ?The rigid asthenosphere allows the thicker continental crust to stand high above oceanic crust. B) ?Oceanic crust squeezes continental crust so that it continuously stands high above sea level. C) ?The continent's mountains float high above sea level because the lithosphere gradually sinks into the deformable asthenosphere until it has displaced a volume of asthenosphere equal to their mass. D) ?The uppermost mantle is thicker beneath continental crust than it is beneath oceanic crust allowing large regions of continental crust to stand high above sea level.
