The earth system provides many crucial services essential to the wealth and health of human society. It provides both the climate and the platform on which we live, the mineral, energy and groundwater resources on which we depend and increasingly a repository for our wastes.

Earth’s tectonic plates are constantly moving. Over millions of years new plates form at oceanic ridges, while others form mountains or even sink back in the mantle and disappear from the surface. The unique geochemical signature of sunken plates can be preserved and reappear in newly formed crust.
