What Is The Most Common Element On Earth

Oxygen is the most common earth element.

The silicate tetrahedron consists of four oxygen atoms arranged as close as they can get around a central silicon atom. Oxygen makes up about 46 percent of earth by weight while silicon makes up about 28 percent and aluminum and iron make up approximately 8 and 5 5 percent respectively. The building block of silicate minerals the essential component that makes them silicate minerals is the silicate tetrahedron. How long will the footprints on the moon last.

Region of the universe we find that only 5 of stars are as massive or more than our sun is. Oxygen o 2 is by far the most abundant element in earth s crust at 46 6 percent nearly half of the mass of the crust. While most elements originate primarily in supernovae or merging neutron stars many vitally important elements are created in part or even mostly in planetary nebulae which do not arise from the first generation of stars. Oxygen is a highly reactive element capable of combining with many other elements to form compounds.

The chemical composition of earth is quite a bit different from that of the universe. The most common elements on earth are oxygen silicon aluminum and iron. Oxygen is vital for sustaining carbon based life without it all animals would die. P after the most abundant elements most elements become much harder to find.
