Tidal dissipation refers to the process by which the energy of tidal forces is converted into heat within a planet or moon. Tidal forces are generated by the gravitational pull of nearby celestial bodies, causing a deformation in the shape of the celestial body as it orbits. This deformation leads to internal friction and the dissipation of energy in the form of heat. Tidal dissipation is an important factor in understanding the dynamics of planetary bodies, such as the Earth-Moon system, and can influence a variety of geological and astronomical processes, including the evolution of planetary orbits and the heating of planetary interiors.
