What Four Elements Make Up Almost 90% of the Earth?

 

Of the 92 naturally occurring elements, the Earth's geosphere - the solid part of the Earth made up of the core, the mantle and the crust - is primarily composed of only four. These four are iron(35%), oxygen(30%), silicon(15%) and magnesium(13%). These elements make up more than 90 percent of the Earth's mass.
