1 Answer

Answer :

Surprisingly, we know very little about what lies beneath the Earth's surface. The scientific community is in generaly agreement that the world beneath our feet is made up of four layers: a rocky outer crust, a mantle of hot viscous rock, a liquid outer core, the seat of magnetism, and a solid, spinning inner core.
