It isn't a static billiard ball.How do you get a ball out of a ball unless it is a ball? You didn't start with supercontinent that broke apart, you started with ocean without a "supercontinent"! Please start from the "beginning"! Do you get it? You cannot start a ball without a ball! 'Splain me the ball without a stupid fucking' "supercontinent" non-ball! You can't! Because no one can 'slain a ball outside of a ball! Duh!
Try this for a quick catch up:

So, how do you 'splain this ball we live on which has always been a fuckin' ball right?!
You know that I love you right? I know that you love me! We're cool!
But, stupid is stupid! And "supercontinent" is stupid! It is stupid because it is not a ball!
No one is saying that a supercontinent was a starting condition. When the earth first formed it would have been very hot and there would have been no surface water. The force of gravity on a body the size of the earth is sufficient to keep the material in the center very hot and in a liquid state. With even more mass it could result in spontaneous fusion as on the sun, but of course we're not that big. But we're really really big. Did you look at that video in my last post?
Irregularities in the surface of the earth - mountain peaks, ocean trenches, continental masses - actually amounts to very little. The earth is actually more nearly a perfect sphere than your average billiard ball. What irregularities there are can be attributed to the extreme heat resulting in circulation of molten material which disturbs the surface.
The supercontinent is not the starting state. It is merely a relatively recent prior state which accounts for the neat fit between some continents which have been split apart by new material thrust up in ocean trenches.

(Specification 16.)
This means that balls with a diamenter of 2.25 inches cannot have any imperfections (bumps or dents) greater than 0.005 inches. In other words, the bump or dent to diameter ratio cannot exceed 0.005/2.25 = 0.0022222
The Earth's diameter is approximately 12,756.2 kilometres or 12,756,200 metres.
12,756,200 x 0.0022222 = 28,347.111
So, if a billiard ball were enlarged to the size of Earth, the maximum allowable bump (mountain) or dent (trench) would be 28,347 metres.
Earth's highest mountain, Mount Everest, is only 8,848 metres above sea level. Earth's deepest trench, the Mariana Trench, is only about 11 kilometres below sea level.
So if the Earth were scaled down to the size of a billiard ball, all its mountains and trenches would fall well within the WPA's specifications for smoothness.
However, it should be also be noted that if the Earth is not a perfect sphere. It is an oblate spheroid and should therefore also be tested for conformity to WPA specifications due to its shape. The distance between Earth’s poles is shorter than its diameter at the equator by approximately 43km. The maximum deviation with the respect to the Earth’s average diameter is half that distance, or 21.5km, which is within the scaled up WPA tolerance of 28.3km.
It can therefore be seen that the Earth would conform to WPA specifications for billiard balls if it was scaled down to the appropriate size, and it could said to be smoother than at least some billiard balls that would be permitted by the WPA.
