What is Earth made of? Interestingly enough, we don't exactly know. We can use magnetic fields and seismic waves to measure the densities and movements of material deep in the mantle, liquid outer core, and solid inner core of the Earth, which provides clues about its composition. We know...
Earth is composed of four layers: the crust, mantle, outer core, and inner core, with the crust being where we reside and the inner core being made of solid iron. The movement of tectonic plates on the crust leads to the constant change in the layout of Earth's continents and oceans....
