Continents shaping from a long process

Here is evolution of continents and oceans by a very long and very slow process. This process start from  very early state of the Earth and the age of Earth is not 4.6 Ga but here we are thinking its age going beyond its current geological age. So actually we are extending Earth geological history by a comparative study of stars, gas giants, rocky planets, moons. This collection of pictures clear that how Earth's continents take by a very slow and very long process that end after complete formation of first state of a rocky planet. Differential rotation and variable oblateness are those basic properties that continuously give shape to the first state of a rocky planet and finalize the shape of continents. For understanding the special shape of continents, plate tectonics, sea floor spreading or entire geology and geophysics we can take help of dynamical nature of our sun and gas giant planets of solar system.
