Early in Earth’s history a global magma ocean cooled and a solid silicate crust crystallized. Modern tectonic plates didn’t exist yet—small proto-plates or rigid lithospheric fragments moved by mantle convection. This produced the first stable continental crust and transformed the surface from molten rock to solid land and nascent ocean basins.
