我张贴在这里,以获得更多的专家信息基于这个问题。如果地球停止旋转,除去导致赤道隆起的离心力,地幔和地壳需要多长时间才能恢复到流体静力平衡?也就是说,马上,几千年,或者几百万年?< / p >
Never mind that changing the rotation in reality would involve forces and timescales that would not really provide this condition. if matter were arranged in such a shape, how long (orders of magnitude) would it take to settle?

Remember that the asthenosphere is defined as the fluid (in geological time-scales) underlying the rigid lithosphere (the rigid plates). It is part of the upper mantle.
