Answer to Question 1

Answer: D

Answer to Question 2

Answer: The differential separation of elements during Earth's formation resulted in heavier elements migrating toward the center of the planet and lighter elements floating to the surface. So yes, the greater density of the mantle contributes to its position beneath the crust.
