Quizplus · Accepted Answer

If the average density of Earth is higher than the density of the crust, it indicates that there is a dense core, which is evidence that Earth has differentiated into different layers. A rotating Earth and a magnetic field are also evidence of differentiation, but the fact that Earth's average density is higher than the crust is the most direct evidence of Earth's differentiation. Earth's surface being 75% water is not directly related to differentiation.
