This unequivocal evidence suggest that Earth's diameter has increased at an accelerating velocity. Today's oceans cover ~71% of Earth surface, which equates to a ~40% increase in Earth diameter...Earth's diameter then, without oceans, would have been only ~7640km (~4747miles) or about ~60% of its current average diameter of 12,734.889km (7913.46miles).
The dominant factor in global expansion today is the expanding molten core -- melting its way upward towards the crust and creating new ocean floor when extruded from the ~65,000km (~40,000miles) of midocean ridges. In the last ~200 million years these ridges have added more than 71% of new ocean surface area to the planet, increasing Earth's diameter by 40%."
