A longer story about the formation of the Earth and Moon:

An AGU talk about accretion and core formation:

My research interests include equations of state and phase diagrams of core and mantle materials, the metal–silicate differentiation of Earth and other terrestrial planets, dynamics of planetary accretion in our Solar System, and various other subjects.

These topics address three fundamental stages of Earth and planetary evolution: the modern-day composition, the core formation process, and accretion.
