D)the planet was formed due to successive bombardments of cosmic debris.
E)nothing can be inferred about such a perplexing level of organization.

Question

Quizplus · Accepted Answer

The process of Earth's interior being sorted into layers suggests that the materials within the planet became sorted based on their density during a molten state, as the denser materials sank towards the center and less dense materials rose towards the surface. This is supported by evidence such as seismic waves and the composition of rocks found at the Earth's surface.
