The iron cycle is an important component of the terrestrial ecosystems. The ferrous form of iron, Fe , is dominant in the Earth's mantle, core, or deep crust. The ferric form, Fe , is more stable in the presence of oxygen gas. Dust is a key component in the Earth's iron cycle. Chemical and biological weathering break … See more The iron cycle (Fe) is the biogeochemical cycle of iron through the atmosphere, hydrosphere, biosphere and lithosphere. While Fe is highly abundant in the Earth's crust, it is less common in oxygenated surface waters. Iron … See more The ocean is a critical component of the Earth's climate system, and the iron cycle plays a key role in ocean primary productivity and marine ecosystem function. Iron limitation has been known to limit the efficiency of the biological carbon pump. The largest … See more Human impact on the iron cycle in the ocean is due to dust concentrations increasing at the beginning of the industrial era. Today, there is approximately … See more • Pérez-Guzmán L, Bogner KR, Lower BH (2010). "Earth's Ferrous Wheel". Nature Education Knowledge. 3 (10): 32. See more On the early Earth, when atmospheric oxygen levels were 0.001% of those present today, dissolved Fe was thought to have been a lot more abundant in the oceans, and thus … See more The iron cycle interacts significantly with the sulfur, nitrogen, and phosphorus cycles.
