Tidal lock and landmass on a Earth-like planet

  1. Mar 21, 2015 #1
    Would an Earth-like planet while getting a tidal lock, get it influenced by landscape of surface? So that the most stable state would be to have a continent on the center of the side close to its star and the other on the exactly opposite side? Or maybe because of hydrostatic equilibrium such landmass is mostly irrelevant as it means that the rock in continental plate is lighter and it mostly equals out?

    By "Earth-like planet" I mean "planet with oceans, continents and active plate tectonics".

    The visible land mass on earth is only a tiny fraction of its total mass. There is no reason to assume plate tectonics would screech to a halt on a tidally locked planet.
