DESCRIPTION:In the early earth\, the lava ocean finally solidifies into a 
 single lithosphere\, and this stagnant lithosphere insulates the underlyin
 g mantle\, leading to thermal expansion\, partial melting and a geoid bulg
 e\, which causes the breakup to trigger the onset of plate tectonics. The 
 global scale breakup of Earth should behave with the thermal equilibrium b
 eing disturbed\, with cooling and warming occurred many times in geologica
 l history. However\, what caused the exceptionally warm and cold periods a
 re still unknown. The speaker presents a simple model of Earth Evolution a
 s a thermal system\, trying to answer many of the questions raised during 
 Earth's
