WebNov 26, 2014 · The fission model was first proposed by Darwin ( 1879, 1880 ). The inspiration for the model was to explain an orbital traceback of the Earth-Moon system while conserving angular momentum. The traceback resulted in an Earth rotating at about 4.5 h/day when the Moon was at the Roche limit (about 2.89 earth radii).

The velocity of the S waves in the core varies smoothly from about 3.7 km/s at the center to about 3.5 km/s at the surface. That is considerably less than the velocity of S waves in the lower crust (about 4.5 km/s) and less than half the velocity in the deep mantle, just above the outer core (about 7.3 km/s). The velocity of the P-waves in the core also varies smoothly through the inner core, from about …
