When local hypergene life prosperous, deposition relative many; Otherwise when the life is in the murky time, relative small; When deposits the many stratum participation internal heat circulation, the surface activity is relatively violent, has the possibility to mean surface Earth life a disaster time, when deposits the few stratum participation internal heat circulation, the surface activity is relatively stable, has the possibility to mean the life an epacme, this is the Earth life periodicity deconstruction and the newborn basic internal reason is at.

当地表生命繁盛时，沉积就相对较多；反之当生命处于低迷时期时，就相对较小；当沉积较多的地层参与内热循环时，地表活动相对猛烈，就有可能意味着地表地球生命的一个灾难期，当沉积较少的地层参与内热循环时，地表活动相对稳定，就有可能意味着生命的一个繁盛期，这就是地球生命周期性毁灭与新生的根本内部原因所在。
