The numerous concurrent geological-driven episodes developed on Earth make it difficult to unravel cause and effect of each geodynamic process alone. Within this complex net, we recognize that meteorite impacts would have played its role in the Earth evolution including life development and/or its truncation. Processes conducted on platforms along the geological time, explored by tidal rhythmites analyses and the rate of lunar retreat calculated for specific time periods, suggest a much more complex inter-relation among astronomical configuration, meteorite impacts? and terrestrial tectonic distribution. Marine flooding along the coasts periodically through tides, helping to the ocean-land temperature balance. In this sense, tides and its sedimentary register along geological time constitute a clue that contributes to understand the evolution of our high-dynamic planetary surface and the evolving life along primitive platforms.
