One significant difference between oceanic and continental crust in terms of the long term evolution of Earth's surface is that______.
A) continental crust is harder to subduct than oceanic crust
B) continental crust is more uniform in composition than oceanic crust
C) oceanic crust preserves a history of ancient deformation better than continental crust
D) oceanic crust contains more radioactive elements that contribute to the heating of the earth
E) oceanic crust is less dense than continental crust

Question

Quizplus · Accepted Answer

Continental crust is composed of thicker and less dense rocks, making it more buoyant and resistant to subduction compared to the denser and thinner oceanic crust. This leads to the development of mountain ranges and formation of stable landmasses on Earth's surface, which affects long term evolution.
