地球的外部三圈层是不是相互渗透的

对不起，我实在不知道该如何用中文回答，所以我先用英文，然后哪位高手帮你翻译一下！

Yes! The easy way to explain it is the sea-floor spreading and the plate tectonics movement.
Ther are both slow movement, but both because the convection current in mantle and inner core.
The convection current past the heat though the lithsophere and the crust to the oceanic floor.
That heat cause the continetal move which is the surface of Earth!
Those example told you the answer!

对。
