Describe how the composition of the Earth's layers changes with depth.

Scientists have long researched and hypothesized the chemical composition of each layer, using seismic waves, volcanic activity and magnetic fields to determine measurements. The crust and mantle are composed heavily of oxygen and silicon while in the outer core and inner core are comprised of primarily Iron. For each deepening layer, the density of the matter increases. Scientists have hypothesized that this is due to the abundance of heavy elements like iron in the outer and inner core compared with lighter elements like oxygen and silicon in the crust and mantle. For example, the percentage of iron in the mantle is 8.72% whereas the percentage of ------- Which choice effectively uses data from the table to complete the example?iron in the crust 5.63%. eliminateiron in the inner core is 85.2%. eliminateoxygen in the mantle is 46.1%. eliminateoxygen in the inner core is >1%.
