Earth's dynamic interior: Multiple compositional components of Earth's deep mantle carried up to surface

Seeking to better understand the composition of the lowermost part of Earth's mantle, located nearly 2,900 kilometers (1,800 miles) below the surface, researchers have developed new simulations that depict the dynamics of deep Earth. These could be used to explain the complex geochemistry of lava from hotspots such as Hawaii.
