Scientists believe that the Earth's core is composed mainly of iron and nickel. It is divided into a solid inner core and a liquid outer core. The heat generated by the radioactive decay of elements in the core is responsible for the Earth's magnetic field.
Scientists believe that Earth has four layers (crust, mantle, outer core, inner core) based on seismic waves produced by earthquakes and volcanic activity. These waves travel through the Earth at different speeds and behave differently depending on the properties of the material they travel through, allowing scientists to infer the presence of distinct layers with varying densities and compositions. This model helps explain Earth's structure and how it influences geological processes.
Scientists believe Earth's core contains iron because it is consistent with the planet's overall composition and density. Iron is one of the most abundant elements in the Earth's crust and mantle, so it is likely to be present in the core as well. Additionally, the magnetic properties of the Earth can be explained by the presence of iron in the core.
Scientists believe Earth's core contains iron because of the planet's density and magnetic field. Iron is a dense material that would sink towards the core during the Earth's formation. The presence of iron is also supported by seismic wave behavior and the Earth's magnetic field, which is generated by the movement of molten iron in the outer core.
Scientists believe the inner core is solid because of its seismic properties. S-waves cannot travel through liquid, yet they can travel through the outer core but are noticeably dampened in the inner core, suggesting it is solid. Additionally, studies on iron under high pressure and temperature conditions support the idea of a solid inner core.
Iron is the primary element that makes up most of the Earth's core. It accounts for about 85% of the core's composition, with the rest likely being nickel in combination with some lighter elements.
because it has the hydro electric power to control the earths magnetic field
scientists think that the earths core is made up of mostly iron, and contains smaller amounts of copper nickel.
The core is a dense chunck of metal that influence the earths magnetic field.
Scientists believe that it is the movements in the liquid outer core that create the magnetic field. Earth's magnetic field affects the whole planet.

Scientists believe that Ceres has a rocky core and an icy mantle
The molten iron and medals inside the earths core are the reasons for the earths magnetic core.
it has been washed into the oceans as the continental crust has eroded.
