Chemical composition. Earth's mass is approximately5.97×1024 kg (5,970 Yg). It is composed mostly of iron (32.1%), oxygen (30.1%), silicon (15.1%), magnesium (13.9%), sulfur (2.9%), nickel (1.8%), calcium (1.5%), and aluminium (1.4%), with the remaining 1.2% consisting of trace amounts of other elements.
Composition by volume:
78.08% nitrogen (N<sub>2</sub>; dry air); 20.95% oxygen (O<sub>2</sub>); 0.930% argon; 0.0402% carbon dioxide; ~ 1% water vapor (climate-variable)
Surface pressure:
101.325 kPa (at MSL)
Surface gravity:
9.807 m/s
