Global dynamic flattening (h) is an important parameter in the study of the Earth rotation.
因为地球自转，它被太阳照亮的一侧是是白天，而处在黑暗中的一侧是夜晚。
As the earth rotates, its side that is lighted by the sun is day time, while its side that is in darkness is night time.
圣诞老人的线路最好是与地球自转逆向而行，而不是悬浮在空中、等着各家各户随着地球自转来到他的脚下。
But instead of hovering over a longitude waiting for the Earth's rotation to bring homes to him, Santa can do better by travelling backward against the direction of Earth's rotation, notes the author.
这种轨道是与地球自转保持同步的。
That is an orbit which turns at the same speed as the rotation of the Earth.
人类的科学已经知晓是地球的核心在驱使着地球自转，地核比地壳转动得要稍微快些。
It is known in human science that the core drives the rotation, and rotates slightly faster than the crust itself.
同样，地球减慢其自转并停下来所需要的时间是几周，而不是几个月，这种情况是曲线似的，因而最后几天（地球）才“刹车”停止转动。
The amount of time that the Earth requires to slow her rotation to a stop is likewise weeks, not months, and this is on a curve so that the last few days are where the brakes are really applied.

地球大陆确实有缓慢的移动(比如几亿年前南极洲在现在的赤道附近)，但那和地球自转极会逆反的说法是不相关的。
There are slow movements of the continents (for example Antarctica was near the equator hundreds of millions of years ago), but that is irrelevant to claims of reversal of the rotational poles.
