Density variations in the crust and upper mantle

Density variations in the crust and upper mantle

Top left: Earth's topography; bottom: gravity gradients as measured by ESA’s GOCE satellite. Right: depth slices through LithoRef18 (Afonso et al.). Colours represent density variation in crust and upper mantle, where blue represents denser material and red represents less dense material. The animation is not to scale.
