A team led by nasa astrobiology institute investigators hypothesized that the oxygen content in the ocean billions of years ago is recorded in iron pyrite rocks. The oxygen combined with dissolved iron in earth's oceans to form insoluble iron oxides, which precipitated out, forming a thin layer on the ocean floor. Numerous examples can be found on almost every continent. Web the formation of rocks from iron in ocean water and the absorption of iron from rock into ocean water is called iron cycling and is important to life, since cells need iron to live. Web its 26 electrons are arranged in the configuration [ar]3d 6 4s 2, of which the 3d and 4s electrons are relatively close in energy, and thus a number of electrons can be ionized.
