21. However, the ecliptic moves around relative to the observer because of the rotation of the earth . 22. The direction of precession is opposite to the daily rotation of the Earth on its axis. 23. The rotation of the Earth is somewhat irregular, and is very gradually slowing due to tidal acceleration. 24. :The plane moves through a medium, air, that in general moves with the rotation of the Earth . 25. For such problems, the rotation of the Earth would be immaterial unless variations with longitude are modeled. 26. The winds are not powered by the rotation of the earth , they are powered by the sun. 27. As a result of the rotation of the Earth , this functions as a decorative and reasonably-accurate clock. 28. The equations also ignore the rotation of the Earth , failing to describe the Coriolis effect for example. 29. Rotation in the outer core is supplied by the Coriolis effect caused by the rotation of the Earth . 30. Francis Bacon was as sceptical of the Primum Mobile as he was of the rotation of the earth .
