The earth is split into four major layers: the crust, the mantle, the outer core and the inner core. The crust is what humans live on, and it consists of only one percent of the Earth's mass. The centre of the Earth is a solid ball of nickel and iron roughly ... Other layers are mostly limestone or dolostone—an altered limestone made up of calcium, magnesium, and carbon dioxide. Still, other layers are mostly shale, or a mixture of fine-grained sand, shale, and carbonate rock. Geologists have assigned names to these individual rock layers.
