Several methods -
Geophysics being a prime means. One knows the size and mass of earth, as boundaries, and then can calculate the internal layers composition and thickness by the behaviour of seismic waves.
Lab work and modelling can predict the types of composition and various T/P conditions
Further, some physical samples (mantle xenoliths; kimberlites, etc) provide actual composition of materials.

i'm no longer annoying. optimal of what we are witnessing now, we've witnessed indoors the geologic record. The supposition of a man made causality has regularly been debunked.. lots of the standards replace dogma has been written via way of pseudo-scientists who're anti-company anarchists. I extremely have little comprehend for a so-call technologies that refuses to enable for peer assessment. the aformentioned companies are complicit in spreading the mythos. One fact, faith isn't technologies. mutually as human beings ask what I "have faith" i desire to strangle them. technologies is approximately documents, and till at last a theory is shown with irrefutable documents, it is not any further suitable than a dogmatic thought device.
