Question

Quizplus · Accepted Answer

Continental crust is much thicker and less dense than oceanic crust, making it more difficult to subduct beneath another plate. Oceanic crust, on the other hand, is denser and thinner, making it more likely to be subducted. This difference in subduction behavior has a significant impact on the long-term evolution of the Earth's surface, as it affects the creation and recycling of continental crust and the distribution of ocean basins.
