you can look at venus and mercury, as the planet cools it shrinks which actually causes something similar to plate tectonics at least for a while.

If we move far enough into the future that the core begins to solidify to the point that volcanism and tectonics are non-existent, what does the surface of the planet begin to look like? Does the planet eventually become fully covered in water due to erosion?
