WebRemnants of early Earth differentiation may still exist in the deep mantle and continue to influence patterns of large-scale mantle convection, sequestration of some trace elements, geomagnetic reversals, vertical motions of continents, and hot-spot volcanism. Keywords accretion, differentiation, giant impacts, magma ocean, early Earth, LLSVP WebDifferentiation is the process by which gravity in the disk spinning around a developing star clumps matter together into planets, asteroids, and other objects. Each continent has its own tectonic plate. Historians and geologists measure time in very different ways. Pick one of these claims and decide whether you think it’s true or false.

WebIn Earth: Planetary differentiation Once hot, Earth’s interior could begin its chemical evolution. For example, outgassing of a fraction of volatile substances that had been trapped in small amounts within the accreting planet probably formed the earliest atmosphere. Outgassing of water to Earth’s surface began before 4.3 billion… Read More
