Regarding the Earth–Moon system by itself (excluding the Sun for the moment) it is known that unless the spin axes of both partners are aligned and perpendicular to the orbital plane, oscillations are excited and these tidal deformations attribute somewhat to the tidal dissipation.<ref>The dissipation by internal fluctuating deformations of the Earth due to the tidal force of the Moon is small as compared with the tidal dissipation in the Earth's oceans and seas, which attribute for 98% of the reduction of the Earth's rotational energy.

This lack of alignment is the case for the Earth–Moon system. Thus, besides the tidal bulges, opposite to each other and comparable in size, that are associated with the so called equilibrium tide,<ref name=Boon>{{

<!--this seems misleading in terms of the oceanography. Is this global average? Cites please!: Because the Moon's tidal forces drive the oceans with a period of about 12.42 hours, which is considerably less than the natural period of the oceans, complex resonance phenomena take place. This, as well as the effects of friction, gives rise to an average lag time of 11 minutes between the occurrence of high water and lunar zenith. This tidal lag time corresponds to an angle of about 3 degrees between the position of the Moon, the center of the Earth, and the location of the global average high water. -->
The tidal oscillations of the Earth introduce dissipation, at an [[average]] rate of about 3.75 terawatt.<ref name=Munk1998>{{citation

About 98% of this dissipation is by the tidal movement in the seas and oceans.<ref name=Ray1996>{{citation

When oscillating tidal currents in the stratified ocean flow over uneven bottom topography, they generate [[internal waves]] with tidal frequencies. Such waves are called ''internal tides''.
The ''[[galactic tide]]'' is the tidal force exerted by galaxies on stars within them and [[satellite galaxies]] orbiting them. The effects of the galactic tide on the [[Solar System]]'s [[Oort cloud]] are believed to be the cause of 90 percent of all observed long-period comets.<ref>{{
