Astronomical and paleontological data on the lengths of year and synodic month are used to study the features of the evolution of the Earth-moon system. Decelerations of the daily rotation of the Earth and of the moon's mean motion, as estimated from empirical data, are compared with the results of calculations based on the McDonald-Goldreich theory. It is shown that the balance of angular moments takes place only when the ratio of the lunar moment of tidal forces to the solar moment is equal to 8. The changes of the tidal dissipative factor and of the Earth's polar moment of inertia in the geological past are calculated. The relation is established between the rotational behavior of the Earth-moon system and the global geodynamical processes in the Phanerozoan.
