Which of these supports the idea that Earth’s Core is largely liquid iron?Group of answer choicesEarth’s large mass can only be explained by large amounts of a heavy element in its interiorEarth’s magnetic field points to the presence of a metallic liquid in its interiorS-waves are absorbed as they travel through Earth’s deep interiorAll of these taken together are the basis for the present model of Earth’s Core
