My apologies for the extra long title, so let's get to the point. There is an Earth-like planet with a very dry personality. Six to ten percent of the surface is water, averaging in at 30-100 meters deep. In turn, 79% of the dry land is salt, suggesting that this was once a waterworld but, due to migration, got right to the inner boundary of the habitable zone and as a result lost most of its water.
With such a near-absolute exposure to air, would the plate tectonics act any differently from those on Earth, a planet in which water makes up the majority of the surface.
