The outer core is solid
Webb1 okt. 2008 · The core of the Earth is made up mainly of iron, in an outer liquid layer and an inner solid layer. The outer core is where the circulating conducting liquid generates the geodynamo, responsible for our magnetic field. WebbThe outer portion of the center, known as the "outer core", is thought to be liquid iron. While the interior portion of the center, known as the "inner core" is thought to be solid iron. This hypothesis is based upon two important observations. First, energy waves known as "shear waves" do not travel through the outer core.

Webbför 2 dagar sedan · The discovery of the liquid outer core allowed another hypothesis: the geodynamo. Iron, whether liquid or solid, is a conductor of electricity. Electric currents would therefore flow in molten iron. Moving a flowing electric current generates a magnetic field at a right angle to the electric current direction (basic physics of electromagnetism).
