earth's core
Deep molten interior
The earth's core is the innermost part of the planet, a dense sphere of iron and nickel lying beneath the mantle.
It consists of two distinct layers: a liquid outer core and a solid inner core, with temperatures rivaling the surface of the sun.
The churning of the liquid outer core generates Earth's magnetic field, which shields the planet from harmful solar radiation.
Scientists study the core indirectly through seismic waves from earthquakes.
