Earth’s core is growing lopsided

While the core is solid iron, it is surrounded by a fluid outer core and then a mantle of hot rock. In the mantle and the outer core, heat from the crystallising iron and hotter rock in the mantle moves upwards towards the surface, pushing colder material down. This movement is what generates the magnetic field. Such a disparity has significant implications for the Earth’s magnetic field, and the convection currents in the core that generate the field are what protects us from dangerous solar particles. The solid-iron core in the middle of the planet has been growing faster under Indonesia’s Banda Sea according to scientists . Do you think the earth is expanding slowly ?
