The key to understanding Earth's evolution, including our atmosphere and how volcanoes and earthquakes form, is to look into the lower mantle, a region some 400 to 1,800 miles below the surface. Researchers simulated conditions at these depths and discovered that the concentration of highly oxidized iron in the two major mantle minerals is key to moving heat in that region and affects material movement throughout the planet.
