Although the Earth is depleted in volatile components relative to its potential chondritic precursors, the isotopic compositions of these elements are similar in Earth and chondrites. A theory to explain these observations suggests that rocky material that formed at various temperatures, locations and times in the protoplanetary disk collected to make Earth.
