Modeled histories of the rotational motion of the Earth. The Earth’s LOD evolution is plotted in time over geological timescales for three models: (i) the model of Farhat et al. (2022), where the evolution is driven solely by oceanic and solid tidal dissipation; and (ii) the model of Zahnle & Walker (1987), where the Lamb resonance is encountered for LOD~21 h, forcing a rotational equilibrium on the Earth; (iii) the model of Bartlett & Stevenson (2016), which also adopts the equilibrium scenario, but further studies the effect of thermal noise, and the required temperature variation to escape the equilibrium. Three curves of the latter model correspond to different parameterizations of the gravitational tide. Plotted on top of the modeled histories are geological proxies of the LOD evolution which can be retrieved from http://astrogeo.eu.
