The separation of the Earth into layers while it was molten was the result of the:
A)decrease in temperature downward toward the core.
B)differing densities of the elements that make up the Earth.
C)gravitational force created by the rotating Earth.
D)initial collection of materials and their position in Earth.
E)presence of water at Earth's surface.

Question

Quizplus · Accepted Answer

The differing densities of the elements that make up the Earth caused the heavier elements to sink to the center, forming the core, and the lighter elements to rise to the surface, forming the crust. This process is known as differentiation. Temperature, gravitational force, initial collection of materials, and presence of water did not play significant roles in the separation of the Earth into layers.
