Question

Describe how surface currents would be affected if Earth did not rotate

Answer 1

If the planet were not rotating, the dominant period for tidal cycles would likely be related to a lunar month rather than to a day. There would also be no Coriolis effect, and these two factors would result in major differences to tides and to ocean circulations. As such, it is likely that there would be substantial differences in both short- and long-term elevation changes that are due to currents.
