PPT-The Complicated Origin of Earth's Water

Jun Wu and colleagues at Arizona State University have examined the issue broadly considering planetary accretion magma oceans core formation mantle convection and interaction of a protoatmosphere with the surrounding solar nebula Their comprehensive hypothesis uses the isotopic composition of hydrogen as a tracer of the sources of water and its processing during planetary formation and subsequent differentiation Here is an overview of their model in six stages .

Nearly 70% of that fresh water is frozen in the icecaps of Antarctica and Greenland; most of the remainder is present as soil moisture, or lies in deep underground aquifers as groundwater not accessible to human use. .
