All of these taken together are the basis for the present model of Earth’s Core.

Here's why:

1. Earth’s large mass can only be explained by large amounts of a heavy element in its interior: Iron is one of the heaviest elements and it's abundant, so it's logical to assume that it makes up a significant portion of Earth's core.

2. Earth’s magnetic field points to the presence of a metallic liquid in its interior: The Earth's magnetic field is generated by electric currents produced by the motion of liquid iron in the outer core.

3. S-waves are absorbed as they travel through Earth’s deep interior: S-waves, or secondary waves, are a type of seismic wave that can only travel through solids. The fact that they get absorbed when they reach the core suggests that the core is not solid, but liquid.

So, all these points together support the idea that Earth’s Core is largely liquid iron.
