Detailed explanation-1: -Earth’s interior layers are ordered by density. The densest layer is the solid metal inner core, the mantle is of intermediate density, and the least dense layer is the lithosphere, particularly the continental lithosphere. The origin of these layers and how scientists know about them is fascinating.
Detailed explanation-2: -The Earth has three main rocky layers, the core, mantle, and crust.
Detailed explanation-3: -Crust, mantle, core, lithosphere, asthenosphere, mesosphere, outer core, inner core.
Detailed explanation-4: -The inner core is at the center of the Earth because it is the densest, made of solid iron and nickel.
Detailed explanation-5: -At the center of the Earth lies the core, which is nearly twice as dense as the mantle because its composition is metallic (iron-nickel alloy) rather than stony.
