A new research attempted to determine the understanding of Earths crust by testing and ultimately eliminating one popular hypothesis about why continental crust is lower in iron and more oxidized compared to oceanic crust

Washington, May 8: A new research attempted to determine the understanding of Earths crust by testing and ultimately eliminating one popular hypothesis about why continental crust is lower in iron and more oxidized compared to oceanic crust. The iron-poor composition of continental crust is a major reason why vast portions of the Earths surface stand above sea level as dry land, making terrestrial life possible today.

New research from the Smithsonian’s National Museum of Natural History and Cornell University deepens the understanding of Earth’s crust by testing and ultimately eliminating one popular hypothesis about why continental crust is lower in iron and more oxidized compared to oceanic crust. The iron-poor composition of continental crust is a major reason why vast portions of the Earth’s surface stand above sea level as dry land, making terrestrial life possible today. The study, published in S...
