How does Earth's interior work?

Answer 1

Earth's interior is structured in layers: the crust, mantle, outer core, and inner core. The crust is a thin, solid layer where we live, while the mantle is semi-solid and convective, driving plate tectonics. The outer core is molten and generates Earth's magnetic field through its fluid motion, while the inner core is a solid ball of iron and nickel, subjected to immense pressure. Heat from radioactive decay and residual formation energy maintains the dynamic processes within these layers.
