Ancient Earth Globe
Some time ago I had this thought: The original (single) continent was round, and about the diameter of the moon. Since the moon was much closer to the earth, it&#x27;s gravitational pull would give rise to a bulge (an earth &quot;tide&quot; if you will), which would be roundish and about the size of the moon&#x27;s visible diameter.<p>I am definitely not a geologist, and this is probably un-provable... but, to me, it sure seemed like a plausible idea.
