Earth is a layered sphere with the high density material found near the center of Earth and the lowest density material located near the surface.
Explanation:
Earth is a layered sphere with high density materials near the centre and low density materials on the surface. The earth consists of four different layers where the crust forms the outermost layer and the core forms the innermost layer.
It is believed that when the earth cooled down, the heavier materials sank down to the centre of the earth and the low density materials rose up at the surface. The crust is formed of rocks which are low in density as compared to iron and nickel which are heavy materials found in the core.
