• Abundance (atom fraction) of the chemical elements in Earth's upper continental crust as a function of the atomic number. The rarest elements in the crust (shown in yellow) are not the heaviest, but are rather the siderophile (iron-loving) elements in the Goldschmidt classification of elements. These have been depleted by being relocated deeper into Earth's core. Their abundance in meteo… WebThe three types of convergent boundaries are continental- continental boundaries, oceanic-oceanic boundaries, and continental-oceanic boundaries.
