Thanks for your presentation, However it seems that you are missing an important point, if the crust slip on the mantle to shift the poles, the earth will still rotates around its axis in the same direction, in in such case what was known to be west in the past, will see the sun rising from there
I can see that you flipped the poles, as well you folpped the direction of the earth rotaion around its axis?
Am i right?
Cheers
Hello Ahmed
The crust will not slip on the mantle, you see, the mantle is contoured being closer to the surface in Ocean basins and deeper underneath continental plates, so the crust cannot slide smoothly around the Earth as it doesn't interface a perfectly spherical mantle. Also, the mantle is a solid, it can
flow over geological timescales because it's warm enough to plastically deform rather than shatter like the brittle rocks we are used to on the surface (as an analogy, think of a ball of dough that can be kneaded at room temperature but becomes brittle if put in the freezer). many people think that the crust floats on an ocean of molten lava, that's wrong, the hot rock off the mantle only melts when decompressed (i.e. in a volcanic eruption or at a mid-Ocean ridge), crossing what is known as the solidus-liquidus as it rises.

However the mantle is certainly coupled to the crust over the course of Earth's rotational period i.e. 24 hours.
