Which of the following best describes the density of Earth's layers? The density of the layers decreases as you move away from the core. The inner core is the densest layer, and the crust is the least dense layer. The density of the layers is in no particular order. The mantle is the densest layer, with 67% of Earth's mass. The density of the layers increases as you move away from the core. The inner core is the least dense layer and is solid rock. The densities of the layers are all the same. It is the temperatures that decrease as you move away from the core. Lithosphere Crust 0-100 km (crust and upper- thick most solid mantle) Asthenosphere Mantle Mantle Crust 2,900 km Liquid Core
