Question

Earth is made of several layers which are made of different elements. Because the _____ elements were pulled to the center by _______, the elements with lower density stayed near the _______

Answer 1

high density gravity and surface

Answer 2

Answer:1(high-density) 2(gravity) 3(surface)

Explanation:This process is known as planetary differentiation and it occurred early in Earth's history, as the planet was still in a molten state. The result was the formation of distinct layers, including the solid inner core, liquid outer core, mantle, and crust. The different layers have different compositions and physical properties, and they play important roles in Earth's geological processes and dynamics.
