Question

Quizplus · Accepted Answer

The fact that Earth's interior is sorted into layers is best explained by the idea that Earth was once in a molten state, during which materials became sorted based on density. As molten material cools and solidifies, denser materials sink towards the center while less dense materials rise towards the surface. This process creates layers within the planet.
