The regular distribution of land mass and ocean floor along equator is divided 30° apart! It fits to the convection cells of the mantle underneath. Just look at this map:
This is one of the proofs of the existence of the convection cell system underneath.
The better we compare the system of convection cells and the distribution of land, ocean ridges and tectonics, the better it all fits! We have had this map on our walls for so long time! Do you want to go into the details of this distribution? Do you want to know the logic behind it?

I am a geologist, graduated from the University of Iceland, and taught geology for a few years. I have gained some knowledge about Earth's inner structure, so I provide this website as my contribution to answer one of the greatest questions remaining within the realm of geoscience. Experiments show that the mantle should form convection rolls when close to the melting point. I took this literally, and calculated the dimensions and shape of these mantle convection rolls. Then I compare that model with the surface. This makes it possible to provide many interesting examples about geology found on my blog.
