Scientists using the KamLAND neutrino detector in Japan have measured how much heat is generated this way by capturing geoneutrinos released during radioactive decay.
WebBecause it is a fluid mix of iron and nickel, currents result when the Earth rotates. This flow of conductive fluid induces electric currents, which in turn creates a magnetic field. This is the "Dynamo theory", which proposes that a "rotating, convecting, and electrically conducting fluid" can maintain a magnetic field. ( 6 votes) Jazz Falcon
Earth's mantle is a layer of silicate rock between the crust and the outer core. It has a mass of 4.01 × 10 kg and thus makes up 67% of the mass of Earth. It has a thickness of 2,900 kilometers (1,800 mi) making up about 84% of Earth's volume.
