登记册显示,在地球历史上已经形成了几个超级大陆:
"最近的超级大陆,泛大陆,形成于大约3亿年前(0.3 Ga)。关于早期超级大陆的历史有两种不同的观点。第一个理论提出了一系列超级大陆:瓦尔巴拉(约36 - 28亿年前);Ur(约30亿年前);Kenorland(约27 - 21亿年前);哥伦比亚(约18 - 15亿年前);Rodinia(约12.5亿至7.5亿年前);以及泛大陆(约6亿年前),它们的扩散产生了最终碰撞形成泛大陆的碎片”。< / p >

I would expect then a new supercontinent to form in some million years, but this implies Atlantic or Pacific Ocean, both with ocean-ridges and divergent margins, to disappear.
Wich one will be closed and wich one will survive to Supercontinent Cycle?
